5 Best Wind Generators For Sailboats (2024)

January 2, 2024

Wind generators, also known as micro turbines, have come a long way since their first appearance on the cruising scene back in the 1970's. Loud, relatively low output and large bladed, these forerunners of the modern day wind generators were both a mechanical marvel and a source of constant consternation. They were basically a small automotive alternator encased in an aluminum housing, with little thought into aesthetics or longevity. Cruisers equipped with an old Windbugger or K.I.S.S. wind generators come to mind as the loud boats in the anchorage no one wanted to be around.

As we all know, there are very few, if any, automotive products that last very long in a marine environment. A large stock of spare parts had to be stored in case of breakage, and daily maintenance consisted of checking the bearings, monitoring the voltage vs. wind speed for signs of decreased output, and rotating the blades into the wind when the boat position changed.

Today's best wind generators boast such features as CAD designed, self-feathering composite blades that are whisper quiet, brushless magnetic alternators, automatic braking and over-charge protection. Boxy aluminum housings have been replaced with sleek, carbon fiber and fiberglass nacelles.

While you may spend a small fortune on a wind generator that has all of these features and more, you can also opt for more budget friendly models, readily available from Amazon, Home Depot and other on-line retailers. The best wind generators are usually the most expensive, but when you are looking at the lower cost models, remember to add in the cost of wiring, mounting hardware, remote monitoring stations and installation, should you choose not to do the work yourself. Not all wind generators are purpose-built for the marine environment. Buyer beware: a turbine designed for the hobbyist on land will not stand up to the rigors of an offshore passage.

Table of contents

As with any mechanical device you are researching, it is a good idea to learn some of the terminology associated with the product. Not all of us know the meaning of 'swept area', 'power capture' or 'yaw error'. Likewise with the electrical side of the wind generator. Learning about output wattage, amps, and microprocessors can seem like a daunting task, but it is necessary to know these terms before you shell out hard earned cash for a quality wind generator.

Some features of wind generators, such as weather-proof coatings and low-noise operation, are common to all makes and models. The use of rare earth elements like Neodymium, (Nd2FE14B, used in magnetic rotors), can add hundreds of dollars to the price of some of these wind generators, but defiantly do add to the overall dependability of the unit.

Some of the more desirable things to look for in a wind generator are:

• Ease of Operation

Also known as plug-n-play, the simpler the set-up, the better. Choose a model that has built-in controllers, that ???makes for less complicated wiring runs. A remote monitor is handy to check on the status of the charging system without crawling into the battery room, or looking up to see if the blades are still turning. If you are ordering your generator and having it shipped, ask your salesman to be sure it has detailed assembly instructions and perhaps an owner's manual in either DVD or booklet form.

• Low Cut-In Speed 

Wind generators work best when the blades are humming along in 20 knots of wind, but that's not always the case. Low cut-in speed means your batteries are getting a charge in the lightest of airs, if only a trickle charge.

If you happen to be ashore when the wind kicks up, you don't want your turbine to spin wildly out of control. Some generators feature a type of automatic speed governor that slows the blades down before they self destruct. Back in the day, you had to pull down on a cord to apply the brakes, then climb up the mast or mounting pole and manually tie off the blades.

• Over-Charge Protection

A 'brake' also kicks in when the batteries are nearing or at full capacity, to prevent overcharging. Some controllers slow the rotation of the blades, others 'dump' the excess power generated through a resistor and heat sink. Wiring an in line reset-able fuse can prevent damage to your batteries should a malfunction occur within the charging system.

• Portability

If you are one of those part-time sailors who cruises for a few months, then dry-docks your vessel for the off-season, choose a light-weight portable wind generator you can set up at home to off-set your electric bill. In case of a hurricane or other emergency when there is no power for days at a time, your wind generator can power cell phone chargers, laptops and rechargeable battery stations. Removing your wind generator and locking it away in the cabin also deters thieves. Portable wind generators that are light can be mounted on higher surfaces without worrying about upsetting the balance of your boat. The heavier the generator, the lower it should be mounted, allowing for safe passage under and around those spinning blades, of course!

It is also a good idea to know your boat's needs and desires before settling for a low cost, low output wind generator. Everything that runs off a battery, including the DC to AC inverter, should be listed, along with their amp/hour draw, to determine how much power you will need to generate. Compare your toys with your reserve amps of your house battery bank. Do you just have a few LED bulbs and a masthead light to run at anchor? Then you can get by with a low output generator. Are you keeping a keg cooler, stereo, disco ball and Netflix going all night? When underway, are you powering SSB, weatherfax, VHF and radar? Then you need a rack full of batteries, and a wind generator with the capacity to keep them topped off.

Speaking of batteries, make sure the wind generator you purchase can charge all the different batteries available. Even if you only have wet-cell lead/acid marine batteries now, you may upgrade to AGM, Gel or even LiFeMgPO4 (Lithium Iron Magnesium Phosphate) batteries in the future. Some wind generators and their controllers are not advanced enough to charge these newer power sources.

Unless you are well versed in the application of electrical theory and DC current, you probably don't know much about wire size and current loss. Even the best wind generator will not function as advertised if the power can not get from the blades to the battery. If you have a long run from your generator to the battery bank you intend to charge, make sure your wires are correctly sized to prevent line loss from resistance and over heating. Most installation manuals will have a wire chart included for DIY installations, and there is always a help line to the manufacturer.

Here are four out of the dozens of wind generators out there that have positive reviews and some of the most desirable features.

1.) Superwind 350, 353

This German manufactured turbine features their patented Auto-Feathering Overspeed-Avoidance System. This is basically the same method a helicopter uses to gain lift, and settle back down. As the wind speed reaches 25 knots, the blades 'feather', or dump air, making them less efficient, and slowing their speed. As the wind lessens, the blades re-pitch, becoming more efficient. This action delivers a steady flow of charging current to the batteries, without going into a shut-down mode to prevent overcharging, as some models do. The Superwind generators also can be combined with solar panels and conventional diesel generators. The Superwind generator family also uses a brushless A/C stator for maximum control of noise and radio interference while the unit is producing power. Two sets of bearings in the 350 make for smoother operation and overall longer bearing life. Available in 12v, 24v, or 48v outputs. At close to 30 lbs, these units are well built and dependable. With a price tag right around $2,700 for the Superwind 350 kit, you can expect German Engineering at it's finest.  https://www.superwind.com/superwind-350-353/

2.) Automaxx

The Automaxx line of wind generators comes in 12v, 24v 48v models, in outputs from 400w up to 1500w. Survival wind speeds are listed at 110mph, but we hope you would never have to put that spec to the test. With very low cut-in speeds of less than 6mph, you will get charging amps on the slightest breeze. All their models come with auto-braking and manual braking system protection, over charge and over-speed protection. The 3600 rotation of the power head keeps the unit into the wind, even when you are docked or med-moored. Simple plug and play setup with an internal MPPT (Maximum Power Point Tracking) charge controller makes the DB400 an easy to install unit, while their other models feature a remote charge controller. Works well when combined with solar chargers. At 16.75 lbs., it is lighter in weight than the Superwind, and it's seven times less expensive at around $400.00 for the DB400.

3.) MarineKinetix MK4

One look at this brand's marketing home page is like an advanced course in wind generator physics. The list of specs for it's models is truly impressive. Not only do they boast all the latest technologies featured in their product, they explain all the scientific jargon they use in terms us simple sailors can understand. They have been providing wind generators to the sailing community for 8 years now, and have a devoted following.

If you need to know the difference between $400.00 wind generators and $1,800 units, check out the product overview section of their website.

The MarineKinetix brand has the the industries best 3 year limited warranty, so they must be pretty sure about their product.

The 12v models of this brand are currently out of stock, due to parts supplier back-orders, but if you are in the market, there are plenty of 24v and 48v units in stock.  https://store.marinebeam.com/marinekinetix-mk4-marine-wind-generator/

4.) Rutland 1200

One of the quieter wind generators out there, the U.K. made Rutland has a long track record of dependability and customer satisfaction. A manual switch is used to stop the blades when high wind is expected, there is no auto-brake. The Rutland can be combined with solar panels up to 20A, and can be also be used with deep cycle gel or AGM batteries, and there is a remote digital display available. One of the Rutland's best features is it's Tri-namic Blade profile design, which achieves low start-up speeds, silent operation in any wind, and maximum power transfer from wind to rotor. Overall good performance and features for the $1,600.00 price tag. https://www.emarineinc.com/Rutland-1200-Wind-Turbine

5.) DuoGen-3

Wind generators are a fairly common sight in most anchorages, and towable generating devices have been around for some time. The DuoGen-3 combines the two into one multi-use charging system. Underway, the high strength carbon fiber mast is lowered down to submerge the blades. At anchor, the unit functions like a typical wind generator. The results are impressive. In the water mode, the DuoGen-3 generates 200 Watts @ 16 amps cruising at 8 knots. Wind generators do not do well sailing downwind, so this may just be the answer. Available in 12v and 24v versions. Charging regulators are not included, so monitors and controllers have to be matched to the unit and sourced locally. https://eclectic-energy.co.uk/

Choosing the right wind generator for your vessel should be a pretty straightforward process, once you have an idea of your needs, the area you will be cruising in, and how long you expect to be 'off the grid'. If one generator is simply not enough because of the size of your battery banks and the load you put on them, you may need to purchase a pair of turbines. Customer support and availability of parts may be the determining factor in your purchase. Talk to other wind generator owners, and get a feel for what they have experienced with their current of former wind generators.

Product Description

The marine industry’s highest rated wind generator.

MarineKinetix MK4+Wind Generator, including Controller - For Lead Acid, AGM, Gel and Lithium Batteries. 

The marine wind generator with a 100% satisfaction guarantee, and the industry's best 3-year limited warranty.   

Double click on the large picture above to scroll through scores of pictures of fellow bluewater cruisers worldwide relying on power from their MarineKinetix wind generator.  See a recent blog from a seasoned bluewater cruiser and Salty Dawg Rally organizer who solved his large energy demands using a combination green energy, including an MK4+ wind generator  here .

The MarineKinetix Wind Turbine has become one of the most popular marine wind generators available due to its advanced technology, superior output, and  super-quiet design.  The MarineKinetix is now considered to be the benchmark among serious cruisers. With a 30% to 50% larger swept area than the most popular marine wind generators, it is simply capable of intercepting more of the available windstream, and capturing more power.  Its sophisticated charge controller displays all the data, including Amps, Watts and Volts, and assures that the power makes it safely and efficiently into your battery bank through a 2-stage smart charging process. No need to buy extra meters , rectifiers, stop switches, or load diverters.  These are integrated into our smart controller. Just add your mounting pole and the wiring to your batteries, and you are ready to start producing green energy.

We are celebrating our 12th year of serial production, and our 8th year producing our latest design, the MK4+ Marine Wind Generator. The MK4+ replaced the popular MarineKinetix MK450.   

The MK4+ includes the following upgrades:

• The Wind Generator body is smaller and even lighter than the original design.  This is accomplished with a shorter, but more upright tail, with a greater surface area, and lower polar moment, for faster, and truer wind-tracking.  This lowers yaw error and improves performance in shifting winds.
• Upgraded asymmetrical pole-shifted rotor with 12 (vs 10) neodymium rare-earth magnets for more power and zero cogging.  Bread-loaf magnet design for optimum air gap.
• Upgraded 36-slot stator with premium heavy-gauge copper windings.
• A new and improved anti-corrosion marine grade finish, which starts with a new high-pressure die-cast magnalium body, which is GEOMET  zinc-nanocoat pre-treated, then top-coated with a high-quality corrosion-resistant thermoset marine powder coating. No other marine wind generator uses this anti-corrosion process
• New double yaw bearings.  Double bearings provide a larger "wheelbase" for the yaw joint, which reduces any free play, which can contribute to vibration and noise.
• Improved silicone o-rings which are totally weather-proof.
• Improved Aero'coustic 20% carbon-fiber filled injection molded blades, which are 18% more rigid than the previous design.
• All new Hybrid Wind/Solar Charge Controller with LCD display - with integrated battery monitor, stop switch, ammeter and watt meter. (no need for expensive monitoring panels).
• Patented 2-Stage PWM Charge Controller - Increases the efficiency of the charge cycle and tops up the batteries quicker and more fully.
• Improved high-precision hub, with tighter blade fastening tolerances, for perfect blade alignment and whisper-quiet operation.
• Improved molded urethane isolator pad, which fits between the pole and the collar.  Molded in "cap" allows it to stay put during assembly.

The great performance of the original MK450 remains.  The above changes are incremental improvements designed to improve start-up speed, ease assembly, resist corrosion, and improve real-world output. The MK4+ is truly a world-class micro wind generator.

Why Consider the MarineKinetix Wind System?

The MarineKinetix Wind Turbine System is simply one of the best performing small wind generator system available for marine use. That is quite a boast, considering all the small turbines out there with catchy names, and bigger advertising budgets, but read on to find out why we believe you'll soon agree.  

The MarineKinetix MK4+ is a simple to install, hands-off, super-quiet wind-energy production system made especially for the marine environment. This high-output, low start-up-speed system utilizes the best of European wind-science in its design. In addition to its leading-edge high-output dual-bearing 3-phase permanent magnet generator, it also features world-class aerodynamic efficiency with its carbon-filled aero'coustic rotor blades, which have been optimized for high torque, low rotational inertia, and exceptionally quiet output. These features, coupled with the included "hands-off" microprocessor-based charge-controller, and its exceptionally low yaw-error, make for what we think is the best marine wind generator system on the market. See why below.

The MarineKinetix MK4+ wind turbine system is a leap forward in wind turbine science. It makes the intelligent compromise between low-speed start-up and high-speed output, all at a realistic and cost-effective price.

What is the wired Remote Stop Switch Connector option?

While the controller already has an integrated stop switch --accessed with the front panel buttons-- some customers who will have limited access to the controller location may wish to mount a secondary  stop switch in a more accesible locaton. So, this option includes a two-pin connector, which attaches to a port on the bottom of the controller, and allows you to run your small-gauge wiring to your  on/off toggle switch. The switch and extra wiring are not included, but this is a very low voltage and low current control signal, so a light gauge wire (18-22 AWG) is sufficient.  For more sophisticated systems (like off-site telemetry systems) a relay can be used to remotely actuate the brake.

Details About the Unique Marine Kinetix Technology:

Our solution is a systems-approach to wind-energy production on-board. The MK4+ system couples several forward-thinking ideas into one "wind-system" which is easy to install, affordable, and maximizes energy production.  We did this by first starting with a low-friction, high-energy-density 3-phase rare-earth magnet rotor design, which came from concepts and materials used in leading-edge green-energy vehicle research. The Neodymium Iron Boron (Nd2Fe14B) permanent magnet rotor uses patented technology licensed from Sumitomo/Hitachi in Japan.  This is the same type of PM rotor design used in the AC synchronous motors in the Chevy Volt and other electric vehicles.   The rare-earth magnetic rotor is a key to its performance and low noise and vibration.  We now utilize an asymmetrical pole-shifted rotor design, which is a advanced method that replaces the heavy mass and cost of older skewed rotor designs, while providing the same advantage of reducing the cogging torque, and improving low speed performance.  We coupled this super-efficient machine with a biomimicry-inspired carbon-fiber-filled blade set, which makes for super-quiet performance while improving overall aerodynamic power.

The results are a turbine that outperforms others in start-up speed, output, and noise.  While other systems are idle, the MK4+ is generating. While other systems are disturbing the peace, the MK4+ is virtually silent. While other systems are struggling to charge, the MK4+ is topping off.

What are the important factors in wind energy production?

Physics dictates the basic performance of all wind generators.  In fact, the power available to any wind generator is a function of the square of the diameter (swept area of the blades) and the cube of the wind speed.  The ability of any specific wind generator to the capture wind efficiently depends on the length of its blades (its swept area) and its Tip Speed Ratio.   Tip Speed Ratio refers to the speed of the tips relative to the speed of the wind.  If the blades spin too fast relative to the wind, they begin to begin to look like a solid disk to the wind, and air piling up in front of the blades effectively blocks the wind behind it.  On the other hand, if the blades spin too slowly, much of the wind passes through the gaps between the blades, and the energy is lost forever.  So, swept area and blade design are the most important areas which the wind generator manufacturer can control.  While the MK4+'s blades are only 8 to 9 inches longer than the typical blade, they sweep as much as 40% more area than the competition.   With a nearly perfect tip speed ratio due to the computer-modeled and simulated blade design, and the impedance load-source matching of the controller, the MK4+ has a higher energy capture compared to most other designs. 

Because of the cube relationship of wind speed to power production, wind speed is absolutely the most important factor in wind energy .  There is no getting around the physics of that.  There is 27 times more power in a 15 knot wind than a 5 knot wind.  The key takeaway here is that regardless of the technology, you need good wind to get good performance from a wind generator .

What affects the ability to maximize output power capture shown above?

Wind generator power is dependent on wind speed, battery acceptance rate, and applied load , so a variable load and a discharged battery was used to characterize the absolute capture power for the data above.  As the wind increases, your wind generator will already be charging full-time, and the battery bank's acceptance-rate, in amps, will decrease as the battery charges and its voltage increases.  So, it is important to understand that by the time the wind is blowing 20 knots or more it is likely your batteries will not be capable of accepting the full amount of amps that any generator can provide.  This is good.  It means that your batteries are reaching a full state-of-charge, and that you have the headroom in power to cover any other loads as they arrive, without further discharging your batteries.  At the end of the day, it is best to think of a wind generator as a free-energy variable power source, whose output changes day-to-day depending on the available wind and the presence (or absence) of downstream electrical loads that it requires to generate power.

Read the following pages to learn about the MK4+, and view the video below to see how it performs against a much more expensive wind generator at very low wind speeds.

Our Integrated "Wind-System": Many popular marine wind generators are essentially sold in kit form, with the user left to decide what method of control they need to get the power into their batteries effectively.  Alternatively, some turbines have an included charging set-up, but offer what is essentially a simple automotive voltage regulator and a load diverter.  This can be a real problem for those wanting to optimize charging and protect their expensive batteries.  It is not enough to just generate efficient and effective power at the generator head. It is just as important to get that power effectively into our battery bank, and to regulate that power based on the battery's specific demands for voltage and current throughout its charging cycle.  By use of an IU charging profile, the system not only can be more efficient, but can also significantly prolong the life of the batteries by preventing overcharging.  Typical load diverter type controllers can only charge your battery to about 80% State-of-Charge (SOC).  This partial cycling is particularly bad for your batteries. Combining the Low Start-Up Speed "Tortoise Approach" with the High-Power "Hare Approach": Having seen both real-world performance in various anchorages around the world, as well as published performance testing over the years, we realized that the best approach out there on the "real water" was to apply leading-edge technology to each component of the system to find an intelligent compromise between the Tortoise Approach and the Hare Approach to wind energy production. A small wind-system that is capable of making power in low wind speeds can take advantage of a long day with low wind speeds by putting small amounts of power into the battery consistently throughout the day and night (the Tortoise Approach). On the other hand, a larger system can take advantage of big gusts or heavy wind by making tons of power very quickly (the Hare Approach).  The perfect solution for us cruisers would be a two-stage turbine that could be the Tortoise in low wind speeds, or protected anchorages, and could be the Hare in a high-velocity wind environment.   By leveraging leading-edge technologies to make incremental efficiency improvements in each of the discrete components of the wind system, we achieved a "sum of the parts" that meets our goals for an ideal marine wind system in-board.   We believe it is the best marine wind generator on the market for those sailors wanting a high-quality, hands-off, high-output, and super-quiet system.  Our real world data and feedback from our customers backs up that claim.  Read on to see how we did it. The Blade Set: We have found that the practical key to consistent production on-board is to start with a large 1.39 meter swept area, and then to apply leading-edge technology to the blade set to extract the maximum amount of energy.  Swept area is the most critical aspect of energy capture, and the bigger the swept area, the more power, period.  Blade length defines the swept area (Area= π r 2 ), and typically the longer the blades, the stronger and heavier they must be to withstand the exponential increase in torque.  The MK4+ solves this issue by using a unique 20% carbon fiber molded blade that is not only long and rigid, but extremely light as well (<300g).   This allows us to produce a blade that is up to 9" longer than the competition, but it weighs much less, and sweeps up to 40% more area. 

We also focused on the airfoils to get a super-efficient, super-quiet, Aero'coustic blade that gives exceptional power while maintaining low-speed start-up capability.  This way the turbine can take advantage of all-day energy production, but also can generate more serious power when the winds pick up.  It doesn't do much good to have great potential generating capacity if the blades never turn in the real world.  Compare our start-up and output to the competition, and you will see the distinct advantage. Details of the Design: The blade and tail design focuses on several key strategies:

• Low Start-up Speeds
• Very Low Rotational Inertia
• Very Low Noise at Optimum Tip Speeds
• Very Low Yaw Error
• Optimized Tip-Speed Ratio (the ratio of the speed of the tips to the speed of the wind)

While our carbon-fiber reinforced blade set has an extremely low rotational inertia, a strong and lightweight blade is only part of the story.  The starting torque on a wind turbine is generated in the blade area closest to the hub, while the power producing torque is produced in the blade area closer to the tips.  By use of German-engineered computer modeling and simulation, a variable blade profile was produced that can react quickly in low wind speeds, yet produce high torque and optimal tip-speed ratios at high speeds.  The blades are produced in a solid-model-patterned single-cavity injection-molding tool, so that each blade is identical in weight and profile.  Using a 20% carbon-fiber filled polymer makes the blade very light, durable, and repeatable. Lightweight blades have a low rotational inertia, which is critical in wind-energy production in the real world. Low rotational inertia allows the blades to accelerate more quickly, which means they can spin faster in lower wind speeds, therefore keeping the tip-speed-ratio (the speed of the tips vs. the speed of the wind) more constant.  Operating closer to the optimum tip-speed-ratio during gusts also allows the turbine to improve energy capture from these sudden gusts as well. Another way to increase aerodynamic efficiency --and to reduce noise on an airfoil blade-- is to manipulate and control the lateral airflow over the foil.  Of course, some of the best engineering solutions often come from mimicking what is already found in nature. Whales and certain fish have amazing hydrodynamic efficiency and stealth through the use of tubercles , or raised and slotted sections on the leading edges of their fins.  Our blades likewise use biomimicry-inspired riblets along the leading edge of the blades, which help the airfoil to create more power at lower speeds, and to operate more efficiently in turbulent air streams.   These Aero'coustic riblets, also prevent the air from traveling down the blade edge and "vortexing" off the blade tip contributing to tip noise. The noise you hear from most wind turbines is the sound of wasted energy. How quiet is it... really ? The MK4+ is extremely quiet, and we have never heard one quieter.  In fact, it measures only 35dB at 5 meters in 10 knots of wind.   At 15 knots, just a flutter, but no tip noise.  As the wind builds the flutter noise will increase.  Above 30 knots, everything exposed to the wind at that velocity will generate some noise, including the MK4+.  To get an idea of how quiet it really is, just watch the video below.  Note that the video was shot with a CMOS rolling-shutter camera, so the blades appear to be turning slowly, while in actual fact they are turning at several hundred RPM.  Video compliments of customer Hayden Cochran on his Island Packet "Island Spirit":

What is Yaw Error, and why is it so important?

This is quite different from most of the other, and more expensive, 400W generators.  The typical marine wind generator charge controller uses 50 year-old technology, which is simply a load-diverter switch, which, upon reaching a set-point, diverts 100% of the energy to a set of resistive elements (essentially heater coils).   So, when the battery reaches its dumpload set-point it isn't actually fully-charged, and this type of Partial State of Charge (PSOC) cycling damages the battery by reducing its capacity, and sulfating the battery plates.  They can't fully-charge the battery because they have no way to dump only the excess power produced, while continuing to top up the battery.  They can only dump all of it. The best scenario would be to have a way to progressively dump power so that the batteries could be fed with only the power that they need at this final stage of the charging process.   

 The controller is very compact (5-5/8" H x 5-7/8" W x 3-1/4" D), fanless, and is designed to be bulkhead mounted.  

It has the following additional features:

(1) Full monitoring capability (Volts, Watts, Amps), no additional battery monitors, shunts, panels, or displays needed (2) Backlit LCD display with clear graphical readout (3) Manual Brake deployment via keypad, so no additional stop switch is required (4) Battery charge level indicator (5) External load control (for managing lighting, etc)

Unlike some other popular marine wind generators which have internal controllers, there are no on-board electronics in the hot and salty elements, and there is no need for additional rectifiers, heat sinks, stop-switches, large resistive loads, or ammeters.  It all happens automatically and safely within the charge controller. It even protects from over-charging and under-charging. It is truly a hands-off charging solution.

Maintenance and Warranty: The MK4+ is designed to provide years of trouble-free service out in the elements, and has a 3-year warranty against defects in materials or workmanship.  We specified a simple and rugged mechanical set that uses very few parts, is easy to maintain, and will stand up to the rigors of the marine environment.  Unlike most single bearing automotive alternator-based designs, our dual low-friction rotor is supported by two low-friction bearings to provide long-life and easy start-up.  The unit is easy to disassemble, understand, and maintain.  The body is made of a lightweight magnesium and aluminum alloy, which is pre-treated with a zinc-aluminum nano-coat, and then a double marine-grade  epoxy powdercoat to resist oxidation and corrosion.   The MK4+ is bluewater tested by full-time cruisers, and like all of the Marinebeam products it is backed by the best technical support and warranty in the business.  Be sure to look at the various customer installation picture above to see some of our installations around the globe.

Marinekinetix mk4 wind generator - highly recommended.

Posted by David Pollock on 28th Jan 2024

I’ve had my MarineKinetix MK4 Wind Generator for over 10 years and it has performed flawlessly! It is an exceptional product! Produces great power and is super quiet. While I also have solar, in the winter down in the Keys or further south, the daylight hours are reduced. But there is usually a 10+ knot wind. Nothing like waking up in the morning with the batteries fully charged. And quiet - I have had guests on my boat in a mooring field comment on the noise of wind generators on other boats. The MK4 is whisper-quiet, built solid with quality materials and they provide great service! Highly recommended!

Posted by Bob Golembicki on 12th Jun 2023

I replaced our very old two bladed Four Wind mizzen mounted generator this past winter with an MK4+ and are very happy with the output and how quiet and well balanced the new generator is as we’ve been sailing around the Chesapeake Bay this year. We’re running the engine to charge only on very calm days and maybe half as much as we had to with our old generator.

Love my new wind gen. It’s quiet. Build quality is top notch. Installation is simple. Much happier with it than my previous wind gen from another brand.

Awesome product

Posted by Bob Osborn SV Pandora on 9th Dec 2022

After spending time with fellow Cruisers that had this unit on their boats, I had one installed this year. I had a wind generator years ago that we noisy and didn't put out much power. This one is as good as advertised. Quiet and powerful. I wrote a blog post about our power generating efforts aboard Pandora. Check it out. http://www.sailpandora.com/?p=12803

Marine Kinetix MK4+ Wind Generator - the highest rated marine wind generator

• Super Quiet 
• Low Wind Startup, High Wind Performance
• Super Reliable
• Maximum Power
• 12V, 24V and 48V Options
• For AGM, VRLA, Gel and Lithium Batteries (see Options tab above for further info)

MarineKinetix wind turbines have become the serious cruisers choice.  Cruising Solutions was an early-adopter of the MarineKinetix Wind Generator, and after having one on our own cruising sailboat for more than 7 years of full-time cruising, and after interfacing with scores of owners, we can honestly say that we believe that this is one of the best marine wind generators available.  We think you will agree.

Check out a recent blog review from a happy MK4+ customer here .

Using advanced engineering, high-efficiency output and super-quiet operation, the MK4+ takes us to another level with a smaller, lighter design;    taller tail for better wind tracking and responding to wind shifts. The large 1.33 meter swept-area intercepts more wind than any other marine wind generator, meaning more power.  The new asymmetric pole-shifted rotor features 12 rare-earth neodymium magnets for smoother rotation and higher output. The 36-slot stator features upgraded premium heavy gauge copper windings for efficiency and durability.

Durability and appearance in the marine environment is also improved with a high-pressure die-cast magnalium chassis being Dacromat pre-treated then thermoset-coated with   a durable marine double powder coating.  

Noise and vibration levels have also been refined by doubling the yaw bearings providing a wider base for yaw response, and reducing vibration.  The  Aero'coustic carbon-fiber reinforced blades have been upgraded as well, making them 18% more rigid.  The included urethane "isolator pad" is now molded to ease installation at the pole and the precision hub has improved tolerances for blade tightening to eliminate any irregularities which might produce imbalance or vibration.  

Below deck, the all-new 2-stage Pulse Width Modulation (PWM) charge controller increases total output efficiency, charging your batteries faster and fuller.   Thanks to modern power electronics, the MK4+ doesn't need diversion loads or heating element to provide speed control.  The microprocessor-controlled charge controller uses stepless electronic load control, automatic braking, and overvoltage and overcurrent protection.  No need for a separate shunt, ammeter, or stop switch panel either.  A matrix LCD screen provides voltage, amperage and wattage info, and the controller features an integrated manual stop switch as well.  A remote (wired) stop switch-enabled controller is also available as an option for situations where the controller will not be mounted in an easily-accessible location. 

In our 20 years of cruising, we have seen and/or tried virtually every wind generator out there and can honestly say that this is the one to buy. It is super quiet...none quieter. It has very high output in the full range of conditions yet requires virtually no maintenance or baby-sitting. It is durable and delivers maximum power from wind to battery with no hassle. Installation is very straightforward with no surprises, and customer support is exceptional. You'll love it so much that Cruising Solutions guarantees your satisfaction!

The box includes:

• Wind Generator
• Assembly Hardware (nuts/bolts/washers, plus spares)
• Isolation pad

You will need:

• Mounting pole and support stays. Mounting collar is for 1.9" OD tubing or pipe (1.5" Schedule 40 pipe is 1.9" in OD).  48-50 mm tubing is also fine.  Stainless or aluminum are appropriate. 
• Appropriate length 3-conductor wire (10/3 cable" for up to 30') from the top of your mounting pole to the charge controller mounting location.
• 8AWG primary wire (red + and black -) from the controller to your battery connection (up to 30').
• 50A fuse or breaker on positive connection to the battery (this is a safety item per ABYC).

Questions or comments, technical or otherwise, please give Jeff a call at 864-275-7837. We will answer all of your questions and help you select the proper setup.

Battery System Voltage -The options include 12V, 24V and 48V wind generators, depending on your DC system's nominal voltage.  Once you decide on the system voltage, you will need to decide about your battery type. 

Battery Chemistry - All 12V lead-acid variants, including VRLA, Gel and AGM use a controller that stops charging when the battery bus voltage reaches 14.4V.  While this end-of-charge voltage is also specified for most 'drop-in" Lithium Iron Phosphate batteries (e.g. Battleborn, Blue Heron, etc), we also offer a LiFePo4 charger that completes charging at 14.2V for batteries that specify this as the end-of-charge voltage (e.g. Victron). We recommend getting specific advise from your battery manufacturer relative to recommended end-of-charge voltage, but note that 12V LiFePO4 batteries are about 98% charged at a final voltage of 14.2V, and there is little capacity to be gained by charging further. 

NOTE: Double or triple the setpoint voltages described above for 24V and 48V batteries respectively.

Remote Stop Switch - While all of our charge-controllers feature a panel integrated mounted stop switch (with soft-braking), some applications benefit from the addition of a secondary switch mounted in a more convenient location.  For this option, you provide the actual SPST switch, but we supply a wired pigtail on the controller for you to connect to.  This allows you the option to run some light-gauge wiring to a stop switch mounted in another location that you prefer.  Choosing the remote stop switch option does not eliminate the integrated controller stop switch.  It will still function.

Best Marine Wind Turbine Generators For Boats

Unless you are happy burning endless amounts of fuel, a marine wind turbine is an essential item fr an offshore cruising sailboat. In this article, we will be taking a look at some of the best wind generators for your boat.

Today’s cruisers carry so much electrical equipment that wind turbines, solar PV arrays, and hydro-generators are becoming more and more common. The marine wind turbine has been around for several decades now and has gradually been refined to give a much higher degree of efficiency. Better alternators, CAD-designed blades, life-sealed bearings, and smart charge controllers make the latest devices more reliable, quieter, and safer.

Things To Consider When Shopping For a Marine Wind Generator

Horizontal axis vs. vertical axis wind turbine.

The majority of marine wind turbines are horizontal axis devices, either upwind or downwind driven. These are powerful and, as such, need speed and/or charge output limiters, or they can burn out the batteries and self-destruct in storm-force winds. Vertical axis turbines are more suited to trickle charging – usually connected to one or two batteries up to 200Ah capacity. The blade design means they are unidirectional and thus have no need for a bulky tail fin to point them into the wind. They are also considerably quieter than most horizontal turbines and much easier to mount and install.

What Blade Design Should Your Wind Generator Have?

Modern turbines usually sport a one-piece, cast aluminum body and, commonly, three aerodynamically designed plastic/composite blades. One of the first of these models, the original Air-X, worked exceptionally well, particularly in high winds. However, it was so noisy that neighboring boats frequently complained, leaving the owner the option of turning it off or moving well away from other boats. Since then, CAD-inspired blade design has significantly helped to reduce ambient noise levels, although none could be termed silent.

Once your battery bank is fully charged, additional energy from the turbine needs to be dissipated, or the turbine stopped. Low power vertical-axis models don’t usually produce enough to warrant fitting a regulator, but the more powerful models all need some form of charge limiter to prevent overcharging. The simplest form of regulation is to switch it off when no further charge is needed. If you electrically disconnect the turbine, however, it can either damage the alternator diodes or carry on spinning at an even higher speed, so most are electrically ‘braked’ by shorting out their output wires, and a high-current switch is usually provided for this action.

If you leave a turbine running unattended, you’ll need an automatic regulator, and there are two systems commonly available. The first lets the turbine continue to spin and produce power, diverting any that isn’t needed into ‘dump’ resistors to burn off the excess as heat. While effective, it is pretty rudimentary, and you have to be careful where you mount the bulky resistors, which can get quite hot. Alternatively, some use this unwanted charge to pre-heat the hot water tank via an immersed element. Other turbines incorporate ‘pitch control’, comprising feathering blades that either flatten out or turn edge into the wind to regulate turning speed at high wind speeds.

Charge Controllers

A variety of automatic charge controllers are available, some more sophisticated than others, and you don’t necessarily need to use one from the same manufacturer unless it specifically states that you must. A basic model has a voltage-sensitive on/off switch that will trigger at a pre-set threshold battery voltage. The more useful controllers have a built-in display for monitoring turbine output and battery condition. Some can also accept and distribute charge from other sources, such as solar or hydro generation.

Here Are Some Of The Best Best Marine Wind Turbine Generators For Sailboats

Auecoor solar wind hybrid system – best marine wind turbine generator on amazon.

The Auecoor Solar Wind Hybrid System is the best system to hook your boat/sailboat with. It is a hybrid system that utilizes both solar and wind power generation. This system is highly efficient, it is designed to withstand heavy wind loads, and it is ready to install on a boat/sailboat. They also produce many models to serve your needs, from 500 Watts all the way up to 2000 Watts in optimal weather conditions. 

All models come with a 400-Watt wind turbine generator, and then you can add as many 120-Watt high-conversion, waterproof and flexible solar panels as you need. This unit is also pretty easy to install. The solar panels are easy to transport, and they come with pre-drilled holes for easy installation. This is my personal favorite kind of setup and the one that I believe is the best for any serious boater. It provides 2 renewable sources of power that guarantee that whether you are making a passage or liveaboard in a nice beach somewhere, you will have dependable power as if you were living connected to the grid.

Air Breeze 200

Although the latest generation Air Breeze, made by Primus Windpower, provides an increased charge output, it is also quieter and should apparently outlast its predecessors. Its low start-up speed (4.2kn) means that, on average, it should be able to produce more energy than some higher-rated turbines over long periods of low-to-moderate wind speeds. Though it only has a maximum output of 200W, its output has been optimized to provide a more constant charge in typical northern European and Mediterranean wind conditions. The new Air Breeze weighs less than 6kg and has an integral electronic charge controller and over-speed regulator, rendering bulky dump resistors unnecessary and making installation considerably quicker and easier.

Leading Edge LE-300 or LE-450

A UK company, Leading Edge supplies wind turbines for both marine and terrestrial installation. The LE-300 and LE-450 are available in 12V, 24V, and 48V versions and are remarkably light, making them ideal for sailing yachts. The output is DC via two wires, and a run/stop switch is supplied that breaks the turbine by shorting the output. The units can also be supplied with charge controllers, a dump load style regulator that allows you to leave the turbine on 24/7 without the batteries overcharging. The three-bladed LE-300 is very light (6kg) and one of the quietest of the three-bladed models. However, its output is poor for a horizontal-axis turbine, although it starts spinning in the gentlest breeze. The five-bladed LE-450 is more powerful (105W at 15-knots) while remaining quiet and stable. Another great feature of this wind turbine is that it is the quietest marine wind generator tested.

Rutland 1200

The latest in the Rutland wind turbine line up, the 1200, is Marlec’s answer to the third generation three-blade, permanent magnet turbine models. More powerful than the 914i, it features a ‘Tri-namic’ blade design, which is said to provide a low start-up speed, very quiet running, and more power towards the top end of the wind scale. With a claimed peak production of 483W (that’s 35.5A at 12V) in 29 knots of wind, the 1200 can also supply a very useful 40W of power in just 10 knots of wind – a more realistic average in most waters.

The 1200’s charge controller has dual outputs for two separate battery banks and can accept up to a 20A solar PV supply. It reduces the turbine speed automatically after winds reach 30 knots, regulating the charge without using dump resistors. It also has an integral start/stop switch and can support a remote display, which connects to the controller via a simple Ethernet cable.

Eco-Worthy Wind Solar Power Kit

What can I say? I just love a good wind-solar hybrid power generator. With this kind of setup, you won’t have any problem charging a 12V or 24V battery bank with this hybrid system throughout the day, in any weather condition. The Eco-Worthy Wind Solar Power Hybrid generator can guarantee enough power for you to remain comfortable on your boat and operate any appliance you need and enjoy your time on the boat. You can purchase any model that fits our needs starting from 400 Watts all the way up to 1,400 Watts. However, always buy a generator that has a higher power output than you think you will need because you almost always won’t be in optimal climate conditions.

The blades on this German-built device are very steeply pitched towards the hub, resulting in an early start-up in lighter airs, and they also incorporate tiny fins along their length, said to quieten them at high speed. The blades have a kinetic rotor pitch control system designed to feather them in very high winds, not unlike the large terrestrial wind turbines. With a charge controller in the circuit, the turbine can therefore be left spinning in all weathers without worry. The output is two-wire 12V or 24V DC, so it could, in theory, be directly connected to a battery bank.

It can also be used with a simple short-circuit stop switch, which will slow it down enough to be tied off. The Superwind 350 can also be supplied with a 40A SCR Marine charge controller, which has two independent, diode-isolated outputs for start and service battery banks and dissipates unwanted energy via two large, wire-wound dump resistors. Nominal power is 350W at 25 knots.

Silentwind 400 Wind Generator

As fitted to all boats in the Volvo Ocean Race and featuring ‘Silent Power Blades’ – hand-laminated carbon blades, successfully tested at hurricane speeds – the latest Silentwind 400+ has improved wind tracking and earlier start-up than its predecessor, the 400. Featuring aerodynamics combined with a three-phase Neodymium-Iron-Boron permanent magnet generator, the 400+ is said to have a start-up speed of only 4.3 knots and a peak output of 420W at 30 percent less rotation speed than other 400W generators. 12V, 24V, and 48V models are available.

The Silentwind has a 3-wire AC output, which connects directly to the matching hybrid multi-stage charge controller that enables trickle charging and the connection of up to 20A of solar PV power. An adjustable boost function increases performance and optimizes the power yield, while the LCD displays all the important charge information. When the batteries are fully charged, the turbine automatically stops or switches to trickle charge mode with a significant reduction in rotation speed. It can also be stopped (braked) manually with the built-in switch on the controller.

Rutland 504 Wind Marine Generator

The Rutland 504 is a small and lightweight (just 3.5kg) mini-horizontal turbine from the UK off-grid power specialist, Marlec. The earlier model (503) has proven to be extremely popular over the years, in both the small leisure craft market and in commercial applications such as remote street lighting and signage, buoy lights, ATON power, etc., and the 504 should prove equally so. Like its predecessor, it is very compact, and its blades are ‘encapsulated’ – i.e., they have a protective ring around them to prevent limbs and clothing from getting caught up in the blades. Its output is better than that of the vertical-axis turbines but nowhere near the more powerful generators listed above. It is, however, notably quieter.

Typical output is around 15 knots of wind is 12W (1A @ 12V), doubling to 24W/2A at 20 knots. It also has a lower start-up speed than the vertical turbines and, although it takes around 10 knots of wind to provide any useful charge, its low-friction alternator compensates for the gusts by ‘smoothing out’ its output. The 504 does require a charge controller if it is to be left unattended.

 Leading Edge Vertical Wind Turbine

The LE-V50 and V150 vertical axis turbines are compact, lightweight, and virtually silent. The V50 measures 270mm dia x 456mm high and is intended for trickle-charging batteries or for running low-power devices. Available in 12V, 24V, or 48V versions, it has a nominal output of 12W but a peak of 70W. In typical waters, this results in an average charge of 0.5-1.0A @ 12Vdc in a fresh breeze. The bigger V150 model has a peak output of 200W but a more typical rating of 24W in wind speeds of 15 knots – double that of the V50. 

Leading Edge wind turbines were originally designed to generate power for industrial data monitoring equipment in very remote areas where there is no other power source; these often supplement solar PV arrays in an off-grid sailing situation.

Final Thoughts

There you have it; these are the best Best Marine Wind Turbine Generators for your boat or sailboat. Whether you are boating/sailing during your holidays or liveaboard full-time, a reliable power source is necessary. It will always provide you with the necessary power to operate your essential electronics, and depending on the power output you go for, it can fill up your batteries without an issue. Remember that when you are out in the water, it will be near impossible that there won’t be enough wind for a marine wind turbine to generate power, so you will rarely be without power. However, that’s why I always sail with both a wind generator and solar panels on board.

Rutland 1200 Marine Turbine Features

The Rutland 1200 Marine combines a highly efficient wind turbine with innovative design features and a technologically advanced controller designed for marine applications. Together they generate real-life levels of power that lead the market of micro wind turbines.

There are three technical advantages the Rutland 1200 Windcharger has over similar models in the market:

Unique Tri-Namic Aerofoil Blades

The refined aerofoil blade profile is purpose designed for quietness, low windspeed start up and high wind peak aerodynamic performance. Each injection moulded blade is identical and perfectly balanced for smooth operation.

Benefits • A rotor that remains virtually silent across all windspeeds. • A very low cut-in windspeed that starts charging at <3m/s (6mph/9kmph) • Unrivalled power generation of 250W at 10m/s (23mph/37kmph) and peak power of 483W @ 15m/s. Our efficient, finely profiled Tri-namic blades ensure that the Rutland 1200 converts the maximum energy available in the wind to charge your batteries.

The Rutland 1200 generator is based on Marlec’s pioneering disk type design. Its low resistance AC operation combines the latest powerful rare earth type magnets with a 3-phase winding and low friction bearings. This is housed in a protective aluminium casing and all manufactured by Marlec in the UK.

Benefits • Cool operation which increases efficiency and reliability. • The low resistance generator works in harmony with the aerofoil blades and controller to ensure that across the whole range of windspeeds the Rutland 1200 generates the maximum energy possible from the available wind. • The generator is sealed to withstand weather conditions around the world.

The overall benefit is greater Ampere hours of energy delivered to your battery.

Elegant and Aerodynamically Styled

The sculpted nose and nacelle efficiently direct the flow of air leading to the built-in tail fin which directs the rotor to the prevailing wind.

Hybrid MPPT Controller Specifications

This purpose designed Rutland 1200 Marine Hybrid Controller incorporates hi-tech features to fully optimise power generation from both the turbine and solar panels and to prevent overcharging the batteries. The facility for charging 2 battery banks is an especially useful feature on-board.

The controller is a key component in the Rutland 1200’s holistic design by Marlec providing intelligence at managing the renewable energy generation. By design the controller will operate with lead acid, AGM and gel batteries. The charge parameters can be programmed using the Rutland Controller Interface cable and PC App for other battery technologies.

Operating Technologies

Maximum power point tracking.

MPPT technology is an intelligent microprocessor controlled feature that electronically optimises power generation. Both the wind and solar energy inputs benefit from the MPPT technology: MPPT enables the Rutland 1200 to commence charging at very low rotor speeds in gentle breezes from just 2.5m/s or 5Knots. MPPT ensures that energy is captured in the most typical low to medium windspeeds experienced daily. Solar Photovoltaic Panel MPPT – low daylight can be enough to start and keep solar panels charging using the controller’s built-in MPPT PV input maximising generation over the whole day.

Overcharge Control

Digital technology used by our engineers very effectively prevents batteries overcharging. Battery voltage levels are continuously monitored and as full capacity is reached the turbine speed is controlled thereby preventing overcharging. The blades may run slowly and automatically resume normal operation as the battery depletes.

Multi-Stage Charging Regime

An algorithm embedded within the overcharge control provides multi-stage charging to maintain it through Bulk, Absorption and Float phases. The system responds to changes in the state of the battery to deliver as much available energy to maintain or reach full charge capacity. This charging regime promotes good capacity and battery longevity.

Connection Features

Temperature compensation.

A temperature sensor is included and when fitted this feature automatically adjusts the charging regime voltage levels according to any variation from the standard 25˚C settings. This ensures batteries reach and maintain full capacity whatever the ambient temperature. Can also be used as an input for a remote shutdown facility. Contact us for details.

Remote Voltage Sensor

This connection facility enables the user to fit sensor wires by to detect actual battery voltage on batteries located >1.5m away. The controller operates based on those readings, overcoming any voltage drop in the battery cables. 2 positions are available.

Serial Data Socket

Provides a connection for user options;

Optional Remote Display, data collection for professional systems or Marlec Controller Interface Cable with App for programming of Voltage and other parameters required for other battery types, e.g. Lithium.

Operating Features

Run / stall button with led indicator.

Used to manually start and soft stall operation. Soft-stall is a deceleration of the rotor until it eventually spins at a slow idle. Bi-colour LED indicates charging status; Standby, Charging and Regulating

Battery LED Indicator

Tri-colour indicates battery charge level.

Electronic Over Current Shut-down

This protection automatically activates in high currents to reduce electrical load on the generator and mechanical load on the tower. This stalls the turbine and resets after 5 minutes, it may cycle in high winds.

Electronic Over Temperature Shut-down

Automatically activates if the controller internal operating temperatures are exceeded. The turbine is temporarily stalled.

Rutland 1200 Specifications

Performance of the Rutland 1200 Marine

Actual Performance Data

We publish our curves based on measured data and use ongoing actual performance data collected and monitored over long periods of time of the turbines running in clear and real wind conditions. This means the turbines are also subject to side winds, upwinds and sudden changes of wind direction (these are the causes of turbulence) experienced at a user’s typical installation. Our curves represent a truer reflection of the power output you can expect from your Rutland Windcharger compared with many other turbines.

Whats a Power Curve?

A power curve is usually given by manufacturers to represent the performance of a wind turbine. Some may be based on theoretical or predicted output and others plot the power achieved under steady state conditions. Wind tunnel testing and turbines run on vehicle rooftops can provide useful information for a manufacturer but power curves derived in this way need to be understood as running in a clear and unobstructed wind flow so they do not represent what is actually achieved in real wind conditions. Power curves from theoretical analysis cannot be regarded as representing what is actually achieved at all.

Energy Yield

A more useful guide of how much power you can expect from your turbine is the Annual Energy Yield . That’s because wind energy is a “cube law,” which means that when the windspeed doubles the power potential is 8 times! Check the Annual Energy Yield bar chart which uses the Rayleigh distribution to calculate the Ampere hours of battery charging you can expect at given average wind speeds per annum. As these are averaged across the year you should consider how these figures will ebb and flow across the seasons when you might expect a higher average during the windier seasons. We often recommend the combination of wind and solar charging to smooth out the daily energy yield.

11 reviews for Rutland 1200 Marine Windcharger

Dean Adams (verified owner) – June 7, 2021

Finally having installed my Rutland 1200 after months of lockdown, I found that I needed a non-standard length of steel for one of the stays. Contacted Rutland, and Stuart James, the Business Development Manager, sorted things out for me – no problems at all, just as he had already done when I couldn’t get hold of the thick 3-core wiring. All fitted and I’m really pleased with it. Can’t recommend Marlec enough for the quality of the product and their customer care. Really great to see such a good British company,

Steve Benn – January 23, 2020

Following problems with ‘low mast height’ due to mounting difficulties I contacted Marlec, my call was returned by Stuart James, the Business Development Manager who after discussions agreed to supply a non standard extra length section to overcome problems. Excellent customer service.

J Doran – October 20, 2017

Hi just to let you know that the Rutland 1200 Windcharger survived the hurricane Ophelia and worked very well and controlled it self very well.

John & Pam Batson – June 19, 2017

We’re now out living aboard enjoying the boat and can honestly say we are delighted with the performance of The Rutland 1200 Wind Generator. Teresa and David were both so helpful.

Helen & Chris – May 17, 2017

With the solar panels we bought from you and the wind generator we are managing well at anchor here , we will certainly be singing your products praises to other possible World Arc participants as the areas are so remote that you have to be self sufficient for energy.

Andrew Geddes – November 14, 2016

As potential purchasers there is a tendency to take the marketing stuff from various manufacturers with a pinch of salt. In this case i think the Rutland 1200 does EVEN BETTER than their publicity. Superb. So quiet i need to look up to see if it is working. A friend of mine has a windgen from guys who reckon they have the most “silent” and i have sailed about 1,500 Nm on his yacht. Makes so much noise he has to shut it down to get some sleep. I love the Rutland 1200, so quiet. “Genial Bee” Jeanneau 43ds

Gordon Ash – September 12, 2016

From consulting and advising prior to the purchase through to commissioning on our 5th Wheel Caravan the Marlec Team has been absolutely outstanding. The Rutland 1200 is powerful yet quiet and now allows us to camp ‘off the grid’ with the confidence of knowing in virtually any wind our batteries are being fully charged. Topping it off being able to monitor the output from the Remote Display from inside our unit is fantastic, thank you again Marlec!

Christopher Brunt – August 5, 2016

First real test of the Rutland 1200 crossing Biscay in Light conditions I have only had to use my engine once and that was to make hot water! The Rutland 1200 has more than kept up with my power demands and it starts up in such light winds which only makes me think that it is windier than it actually is ! Excellent product I can well recommend .

P Landino (E-Marine Systems) – June 14, 2016

We’ve had two of our recent customers return their purchased turbine from another manufacturer to be replaced with the 1200. I think that’s a good sign.

H Tibbs – June 14, 2016

The wind Charger is absolutely brilliant WE LOVE IT !! In Fact Chris just sent an article to Yachting World and gave The Rultand charger very positive coverage. We have had varied weather and loads of wind 35knt whilst we were in Baiona and she just kept wizzing nicely . We have a nickname for the charger and have called her Twirley . It is so nice not to have to use the engine to charge the batteries . We are running two fridges and two chart plotters and all the instruments and haven’t had to run the engine for charging at all .

J Delisky – June 14, 2016

So that you know it was a tough decision between the 1200 and what seems to be the most popular unit in the Caribbean, the D400. Typically I avoid new products but made an exception in this case. This was based very much on your company’s reputation with previous units. My decision has been confirmed by the support you’ve provided. I’ll certainly advocate the Rutland 1200 and Marlec moving forward. Thanks again!

Best Wind Generators for Sailboats of 2024

Sailing gives us freedom: we don’t need a motor or fuel to travel the oceans. That freedom isn’t absolute. Most sailors still rely on electricity for lighting, refrigeration, small appliances, and to run the electronics that we rely on for navigation and safety. That means we need batteries, and if we rely on batteries, we have to charge the batteries. Since we’re already using the wind to move us from place to place, it makes sense to use that same energy source to keep our batteries charged up and ready for action. Wind generators are increasingly becoming a standard feature on cruising sailboats, and a wide range of products have emerged to meet the demand. This review of the best wind generators for sailboats will help you select the product that best meets your needs.

The durable polypropylene and fiberglass construction of this affordable wind generator resists corrosion and all parts are protected from both water and UV radiation. 

Some reviewers complain that these units fail to spin at the advertised cut-in speed and generated less power than expected, but many others reported performance consistent with expectations. It’s difficult to say whether these deficiencies are caused by installation issues, inconsistent products, or excessive expectations. It’s always good to test your unit on arrival and assure that it’s doing what it needs to do! 

As with all units listed here, you’ll need a mounting pole for this generator, but other than that it’s ready to install: the charge controller is built-in and you can wire it to your battery pack and forget about it!

• Auto-Brake Regulator Slows Blades When Battery Is Charged
• Built-In Charge Controller
• Marine-Specific Design And Materials

BEST OVERALL SMALL WIND GENERATOR

The Air-X Marine is the Rolls-Royce of small wind turbines. It’s made entirely in Colorado, and the relatively high price is reflected in the features and overall quality of the unit. It costs three times as much as an entry-level unit with the same output rating, but you get what you pay for.

The unit squeezes its mechanical and electrical components into a tiny ultralight package that is ideal for higher mounts and requires much less effort to secure than heavier bulkier units. You get a sophisticated built-in charge controller with external indicators to tell you when you are charging and when your batteries are full, and the unit is fully use-ready. Just wire it to your battery bank and you’re ready to charge.

This unit is one of the most popular sailing wind generators on the market for good reasons. It’s quiet, efficient, and gets the job done with no extra effort and very little maintenance.

• Electromagnetic Brake System For Overcharge Control
• Low-Noise Carbon Fiber Blades

BEST OVERALL LARGE WIND GENERATOR

This is the big boy: a full-on 2000 watt marine wind turbine, ready to install and power up some serious juice to feed those hungry batteries. The unit is designed to be effectively maintenance-free, with a coated cast aluminum body and carbon fiber blades engineered for quiet operation. There’s an external charge controller with an LCD output display to let you know what you’re generating and what your charge status is. Electromagnetic braking prevents potential damage from high winds and overcharging.

You’ll need 45 knots of wind to generate the full 2000 watts, but even at lower speeds, you’ll be putting out enough power to keep your batteries topped up. Paired with a solar array, this wind generator will give you all you need for complete energy independence!

Missouri General Freedom II

• Weight : 59 lb.
• Blades : 11
• Optimal Power AT : Not Specified
• Voltage : 12/24V

• Rust-Proof Galvanized Components With Zinc-Plated Hub Make This Wind Generator Almost Indestructible
• 28-Magnet Generator For Maximum Power
• Aerodynamically Tapered Carbon Fiber Blades

BEST POWER-TO-PRICE RATIO 

If you’re looking to step up to a higher-output wind system without spending a fortune, Missouri General delivers with the Freedom II. This unit adopts a radically different design philosophy, featuring 11 carbon fiber blades to get maximum power out of wind in the lower end of the charging range. The Freedom II uses a permanent-magnet generator and several other unique design features to achieve high efficiency and durability.

This unit is quite inexpensive on a price-for-power scale, but it does not arrive installation-ready and you’ll have to add a charge controller, a dump load to protect your battery from overcharging, and cables. You’ll probably also need to have an electrician install the unit to assure that those components are correctly connected and working as they should!

Nature Power 400W

• Optimal Power AT : 27 MPH
• Minimum Wind Speed : 7 MPH
• Marine Grade Coating And Sealing For Durability
• Low-Noise Carbon Composite Blades
• Smart Charge Controller For Maximum Output

BEST LIGHTWEIGHT BUDGET WIND GENERATOR

Nature Power turbines are designed specifically for marine use and offer a durable, corrosion-resistant cast aluminum body and whisper-quiet carbon fiber blades. There’s a specialized electromagnetic braking system designed to keep the unit within its electrical and mechanical limits without the wear and tear associated with mechanical braking and a smart controller that adjusts the voltage-to-current ratio for peak charging efficiency. The low weight of the unit makes it ideal for mast installations or other high mounts. As with any relatively low-output wind generator, you can’t expect to rely on this unit for all of your charging needs. It’s very well suited to use in conjunction with solar panels: on hot, still days the sun does the work, and when the weather turns sour or you’re out at sea, the wind will kick in with its share. This is an excellent choice for the wind component of a combined solar/wind generation system.

THINGS TO CONSIDER WHEN BUYING A WIND GENERATOR

It’s important to recognize that while wind power is useful, it isn’t magic. Most modern wind generators will begin generating power in quite light winds, but the output may be minimal and you’ll need sustained higher winds to deliver the charge you want.

If you’re moving downwind, you may get less charge than you expect: if the wind is at 20 knots and your downwind speed is 8 knots, your wind generator will be effectively receiving 12 knots, not 20! Many sailors find that a wind generator combined with a solar array is the most effective power solution, and some add a towed generator that generates power when dragged through the water as an additional option. The power mix that best suits you is something you’ll have to decide, but there’s a good chance that wind will be part of it!

Read through these things to consider to get a better sense of how to choose which wind generator is right for you so that you can get back on the water and enjoy the wind in your hair without worrying about losing electricity unexpectedly!

MANAGE YOUR EXPECTATIONS

A common complaint about wind generators is that they don’t deliver as much power as expected. This is more often a problem of simple physics than an issue with defective units or improper installation. The power delivered by wind increases with the cube of the wind speed, meaning that (keeping things very simple), a 20-knot wind delivers 8 times the power of a 10-knot wind. If you expect a unit that’s rated to deliver 400 watts of power at 28 knots of speed to deliver 200 watts at 14 knots, you will be disappointed, and it won’t be the unit’s fault!

While most units will cut in (start working) at 6 to 7 knots, don’t expect to generate measurable power until you reach 10-12 knots. Remember that if you’re on a downwind heading the apparent wind – the wind speed actually experienced by your generator – will be wind velocity minus hull speed. And remember that most anchorages were chosen because they are protected from the wind.

All in all, you are likely to find yourself generating less power than you expected. That doesn’t mean the installation is useless: it will contribute, it will charge your batteries while you sail, and if used in conjunction with solar panels, it can meet your charging needs. It’s a useful tool, not a magic bullet!

INSTALLATION

Your choice of generator will be affected by your installation options. Some sailors opt for masthead or mizzenmast installations, which can receive up to 50% more wind than lower placements but which are less accessible for maintenance and involve longer cable runs with more resistance. If you’re looking at such an installation, you’ll want a lightweight, low-maintenance unit. Most sailors prefer installation above the cockpit or transom, high enough to keep blades away from people and equipment but low enough for easy access and relatively short cable runs.

WATCH OUT FOR HIGH WINDS

Manufacturers claim very high maximum wind tolerances, but these are often based on wind-tunnel tests using controlled wind from a single direction. Turbulence can increase the burden on the device, and if you’re expecting wind in excess of 50 knots, taking down the generator is a wise precaution.

THE NOISE FACTOR

Noise and vibration were once huge problems with wind generators, with users reporting everything from a repetitive whump to a screaming howl. Modern construction and improved blade design have made turbines much quieter, but noise and vibration can still be issues. It’s great to generate power while you sleep, but not so great to have your generator keeping you awake! You may wish to check out some working installations to get a sense of how much noise is involved.

If you’re wondering whether to go with wind or solar, All At Sea and eMarine have useful articles weighing in on that eternal debate. For more information on Wind Generators, try these articles from Yacht Unlimited and Sail .

FEATURES EXPLAINED

About those numbers.

Rated Output is the maximum number of watts a unit can put out under ideal conditions. These numbers are based on wind tunnel tests and are rarely if ever achieved in the field.

Minimum (or “cut-in”) Wind Speed is the wind speed required to turn the blades. Very little power will be produced at this level.

Maximum Power is achieved at a specific target wind speed. Most units are designed to begin braking or “cutting out” power at speeds above this level.

Blade Diameter is the end-to-end distance between blade tips. You’ll need to consider this distance when mounting the unit to keep the blades well clear of any obstructions.

Voltage is the unit’s output voltage, which needs to match the voltage of your battery array.

Maximum Wind Speed is the highest wind the unit can survive. This may be substantially reduced by turbulence!

SOME COMMON FEATURES

Charge Controllers are devices that regulate the output of your generator to maximize the charging of your battery. Some units have built-in controllers with different levels of sophistication, and others do not.

Braking may be mechanical or electromagnetic and is used to assure that the unit’s rotation will not exceed its mechanical or electrical limits. Electromagnetic braking is claimed by some to produce less wear and tear.

Tracking Systems keep the blades facing the wind and keep the unit from spinning on its mount axis, which will twist the cable and damage the installation.

Blades may be fiberglass or carbon fiber, with more expensive units usually using carbon fiber. Many blades are designed to flex and shed wind if wind velocity exceeds design limits.

Corrosion Resistance is achieved by using a variety of coatings and materials. Marine environments place an aggressive burden on materials and both exterior materials and sealing are very important to keep units working.

A Dump Load is a device that diverts excess power to resistors that radiate it as heat, protecting batteries from overcharging.

Features of the Superwind 350-ll

Patented blade adjustment.

Similar to large wind turbines, the rotor blades of all Superwind generators are automatically adjusted above the nominal wind speed and the aerodynamic loads are limited directly at the rotor. High forces on the structure are avoided, significantly increasing safety and reliability. At the same time, a Superwind continues to generate full power well above the nominal wind speed: situations in which other wind turbines have to be shut down.

The adjustment mechanism is maintenance-free, fully protected and integrated into the hub. The purely mechanical operation works reliably even in the event of external malfunction and keeps the wind turbine in a safe operating state, independent of electronic components.

"Silent Power" rotor blades

Rotor blades optimised in the wind tunnel that are barely noticeable during operation due to the structure of the rotor blade surface (keyword: sharkskin).

Damped wind tracking

The wind vane tracking system is designed to reliably turn the wind turbine into the wind when there is sufficient wind to generate electricity. The Superwind generators are equipped with a damping system to ensure that they always track into the wind, even in turbulent locations. The damping of the wind vane also prevents unwanted oscillations caused by waves on buoys or ships.

Integrated vibration isolation

The Superwind 350-II's noise decoupling is built directly into the mast mount, so there is no metallic contact between the mast mount and the tower. This means that the generator hum cannot be transmitted through the mast and no additional damping elements are required in the mast or at the base of the mast. This results in a significant reduction in noise levels, making the Superwind 350-II virtually undetectable below deck, even on aluminium and steel hulls. The rotor blades of all Superwind turbines are fully synchronised via star hubs. This makes them more resistant to start-up wind and turbulence than previous technologies.

Star Hub is the rotor hub design of our current wind generators. The patented rotor blade adjustment works fully automatically at high wind speeds, regulates the output above the nominal wind speed and limits the load on the generator. The new star synchronisation of the rotor blades makes all Superwind turbines more resistant to strong winds and turbulence compared to older technologies.

Coordinated overall concept

Because we develop our systems in-house, all components are perfectly matched. The electric generator, for example, is precisely matched to the aerodynamics of the rotor and delivers charging current even at low wind speeds. Designed as a brushless synchronous machine and powered by neodymium magnets, the generator has outstanding efficiency across the entire power range.

While conventional generators have to shut down when the wind is too strong, the rotor blade adjustment and the generous dimensions of the generator ensure that Superwind generators can deliver full power at all times, even at very high wind speeds.

With the Superwind 350-II, you are ready to take on the challenges of blue water sailing or short trips.

Blowin’ in the Wind: The Best Marine Wind Generators

Whether you're walking down a road, climbing a mountain or sailing on the sea (with a white dove, maybe), there's one constant: Wind. 

Bob Dylan may have had all sorts of other ideas in mind when he wrote "Blowin' in the Wind," but the idea stands. When the wind blows, power is supplied. The times, they are a-changin', and we boaters need power out on the water for motor batteries , stereos, marine electronics, lights, bilge pumping and what have you.

Sure, when you're in your marina slip, you can just hook up to power. But when you're out on the water, that's not exactly feasible. Plus, it's always good to do everything we can to save the environment, reduce our carbon footprint and what-not.

Today, we're going to discuss the best marine wind generators and turbines for boats to answer your power problems whether you're a leisure powerboater, a liveaboard sailor  or own the wooden schooner Water Pearl (that would be Bob's, of course). More Dylan references may or may not ensue.

What Is a Marine Wind Generator?

You know those wind turbines you see standing tall on land? Well, a marine wind generator is essentially the same thing. It's just smaller and attached to a boat (or a magic swirlin' ship).

Swirlin' ships aside, marine wind generators work by harnessing the kinetic energy of air, or to be exact, the wind. Once caught, the wind is converted to a rotational motion that turns an alternator, which then produces electrical energy. This energy can be used immediately or stored in batteries (12V or 24V) for later use. Voila, it really is magic!

Parts of a Marine Wind Generator

• Blades are those things on the end that turn (similar to the blades on a ceiling fan). They're connected to a shaft that turns with the blades.
• A tower or mast , usually about 9' tall, is the pole that attaches to the boat (like a sailboat mast) and holds the blades up in the air.
• Stay poles , usually two 8' poles, are used to hold up the mast. They're attached at an angle to keep the mast in place.
• Clamps, crimp rings and TY wraps are used to keep it all together.
• Control panels and electronics let you make sure everything is operating as it should.

Benefits of a Marine Wind Generator

• Economical (free energy!)  - This is probably the biggest reason to consider a marine wind generator. Once you've made the initial purchase cost, you've got all that free energy coming in. We boaters need all the free we can get.
• Relatively low maintenance  - Marine wind generators are pretty much an install it and forget it kind of thing. Like the song, it's just there blowin' in the wind.
• Environmentally friendly  - We all want to conserve energy, go green and save the environment (or we should if we really love the boating lifestyle like we say we do). Marine wind generators don't add to air or water pollution, and they don't emit greenhouse gases.

Disadvantages of a Marine Wind Generator

• Noise and vibration:  They can be quite noisy (especially when the wind is really kicking it up). You'll be on a rockin' boat whether you want to or not.
• No wind, no power:  This one is self-explanatory.
• Very high winds:  On the flip-side, marine wind generators can be damaged in very high winds. There are, of course, ways to avoid this problem. You can use a regulator or charge controller that senses the battery voltage and reacts in the appropriate manner. Some wind generators can change the pitch of each blade in response to the wind. Others have flexible blades that bend easier in the wind (this method, however, can cause even more noise).

Featured Boat Care Product

Check Price on Amazon - Better Boat's Boat Soap is 100% biodegradable and safe to use in marine environments. It rinses clean and doesn't leave a slippery residue. Simply spray with a hose and nozzle.  Use a microfiber cloth if you need a bit more scrubbing power.

What to Consider When Choosing a Marine Wind Generator

• Decide how much power you'll need for things like the stereo, navigational electronics, refrigerator, lights, laptops and other devices.
• Where do you spend most of your time on your boat? Ocean or inland? You'll want to gauge the amount of wind generally found in that area.
• What are your normal cruising speeds? Obviously, any wind is good, but most marine wind generators don't provide much power below eight knots.
• What are the water and weather conditions in your normal navigational routes? You'll want to align your choice of wind generator with how rough or calm the water is, as well as the types of weather typically found. As an example, with higher wind speeds, you'll want a bigger blade sweep to get even more energy.
• Where do you want to put it on the boat? I've seen marine wind generators attached to the back of a sailboat, on a hardtop and at the very front of the boat. Take into consideration where it will be out of the way as far as foot traffic on the deck.
• Are there any noise restrictions? Remember when I said marine wind generators can be noisy? I wasn't kidding. Noise restrictions are a real concern in certain places: narrow inland waterways, residential communities and businesses.

Best Marine Wind Generator 2021

Getting your hands on a boat is only the first step towards becoming a true sailor. Once you’re comfortable with how your boat handles and operates, it’s time to start customizing it to your liking. Installing something like a marine wind generator can let you enjoy some of the amenities you’d only find onshore.

However, even budget marine generators can be relatively pricey compared to other, more minor fixtures. This means that a little bit of research can go a long way when it comes to saving you money and finding the right product will be sure to work. Today’s review guide will be based on finding the best marine wind generator .

We’ll look at six different turbine generators in this guide, each of which excels in its own way. After our reviews, we’ll also explore some of the key features to look for in a high-quality marine wind generator, and we’ll answer some frequently asked questions. For now, however, let’s get started with our reviews.

Best Marine Wind Generator

Our top pick: tesup master940 wind turbine kit, key points at a glance.

• Durable injection-molded fiberglass blades
• Lightweight aluminum body
• Turbine blades engineered for quiet operation
• Cooling fins help dissipate heat around the generator body
• Generates up to 900W of power

The Details

The best marine wind turbine is the TESUP Master940. As the name suggests, this model can produce over 900W of power, making it the most powerful turbine on this list. Sweet!

However, there are more reasons to buy this wind turbine than just its high level of power output. Here’s the power output curve:

This model has some of the best build quality we’ve seen in a consumer wind turbine. All of the Master940’s components have been built to be as strong and light as possible. This is evident when you take a look at the materials used in its construction, with fiberglass blades and a strong yet light aluminum body.

The Master940 is equipped with a few clever features that help keep it running smoothly and prevent long-term damage due to overspeed. Unlike other wind turbines, this one comes equipped with a load dump system consisting of resistors in the charge controller that improves the reliability of the Master940’s wiring and circuits.

This wind turbine system is also designed to cut down on the amount of maintenance that you have to perform, as it comes equipped with a charcoal-free sliding contact that won’t have to be topped up.

The Master940 is designed to be used in all environments, and it won’t fail at high or low temperatures because of its inbuilt resilience.

The aluminum housing has better thermal transfer characteristics, and the inclusion of fins helps generate wind-flow that dissipates the heat into the surrounding air.

This turbine’s only weaknesses are its high price point and its relatively complex setup process, but they’re both a small price to pay for the Master940’s impressive performance and quality. This the best marine wind turbine available.

Our Runner Up: 400W Lantern Vertical Wind Generator by Happybuy

• Double bearing design helps reduce vibration and noise
• Microprocessor control gets the best performance out of the turbine at all wind speeds
• The vertical turbine design offers omnidirectional performance in all wind conditions
• Effective at harnessing the turbulent wind in the wake of a boat’s superstructure

While our runner up wind generator may not look as traditional as some of our other top picks, there’s a reason why the Happybuy Lantern-style looks like that. The layout of the fan blades on this model is designed to keep the power output constant no matter which direction the wind is coming from.

The improved omnidirectional performance of this wind generator makes it ideal for use on boats, especially those with a more cluttered superstructure. If you only have room for your wind generator near the back of your boat, you’ll still be able to generate power using that disrupted windflow.

Along with its unique design, the Happybuy 400W lantern wind generator is easier to assemble than most of the competition. If you don’t have much experience working with wind generators, then you can get this model up and running on the same day that you receive it.

Keep in mind that this model is mainly designed for faster wind speeds, as you won’t get much power output at speeds below 25 mph. While it will start spinning at lower speeds, you simply won’t get much useful power out of it. If you’re looking for a relatively well-built unit with powder-coated components and the ability to operate in a variety of wind directions without adjustment, this model is a great fit.

Best Budget: Happybuy 400W Wind Turbine Generator

• Features a corrosion-resistant design with an aluminum housing and stainless steel fittings
• The magnetic circuit allows the generator to run at low wind speeds
• The automatic braking system prevents damage from high wind speeds
• 400W of power output

Compared to the previous model from Happybuy, this 400W wind generator features a more traditional design, and it’s one of the more affordable options on this list. Despite featuring such a low price point, this Happybuy wind turbine is surprisingly reliable, and that’s one of the most crucial features to look for in a budget turbine.

Here’s the power output information:

To further improve its long-term reliability, this Happybuy wind turbine is made out of corrosion-resistant materials that have further been treated with a coating to reduce damage from UV light and salt spray. This model’s durability also makes it more effective in gusty conditions where other models may even be damaged by high wind speed.

Keep in mind that this wind generator doesn’t come with a mounting pole, so you’ll either need to buy the official one separately or you’ll need to create your own. While you’ll have to get creative when you come up with a mounting solution, assembling the turbine itself is surprisingly easy, and you can even do it if you’re a beginner.

In case of overspeed, the Happybuy wind turbine is equipped with an automatic braking system that will prevent the components from being damaged. Overall, this model may not be the best-performing on this list but it offers much more than its competitors within the same price range.

Best for Ease of Installation: SHZOND 400W Wind Turbine Generator

• Max rpm of 800
• Fiberglass reinforced blades
• Comes with mounting hardware included
• 400W of rated power output

The SHZOND wind turbine generator may look like a pretty standard one at first glance, but it’s designed to be a perfect fit for customers who are new to marine turbines. To that effect, the SHZOND 400W turbine is designed to be assembled in less than an hour, and it’s remarkably easy to use once you have it built.

This is also one of the lightest wind turbines on our list, as the housing is made out of vinyl while the blades are made out of fiberglass. The only metal parts you’ll find on the SHZOND wind turbine include the nose cone and the stainless steel mounting hardware and screws that keep all of the parts together.

Compared to other wind turbines on this list, this model from SHZOND will start spinning at lower wind speeds, only requiring about 10 mph speeds to start generating power. Keep in mind that this model is relatively sensitive to rapidly shifting wind directions because of the flexible mounting, so you may have to anchor it in a particular direction if you don’t want it to spin out of control.

This model’s control unit is also equipped with an auto-shutdown feature, ensuring that you don’t overload the battery.

Despite being easy to assemble, this SHZOND wind turbine comes with relatively vague instructions, so you’ll have to rely on the pictograms and what other customers have said about the assembly process. Even though this may seem like a pretty major annoyance, the SHZOND wind turbine’s strengths more than make up for it.

Best for Output Per Dollar: Automaxx Windmill 600W Wind Turbine Generator

• Weather-resistant construction and corrosion-resistant materials
• Features both automatic and manual braking systems
• 600W of power output
• Comes with a one-year warranty

This Automaxx wind turbine has a higher power output than many of its competitors at the same price point, so if you’re looking for something powerful that can provide good value for money, this is it. To make this model more suitable for use in marine environments, it is made out of corrosion-resistant materials.

This model has a maximum rated speed of 30 mph since it doesn’t feature a mechanical braking system, so it is more suitable for regions without extreme wind gusts. However, to make up for this, the Automaxx wind turbine has a relatively low cut-in speed, so you’ll have a broader band of wind speeds in which this model can operate.

The Automaxx turbine also swivels in a 360-degree arc so that it can be adjusted to match the wind direction. Unlike some of its competitors, it takes a lot for the wind to push the turbine out of alignment on its own, so you won’t have to worry about putting extra work into securing it so that it remains facing the wind.

The included charge controller features a wattage display and can easily be wired directly to your battery or battery bank. Here’s a basic wind turbine wiring diagram:

One of the main weaknesses of this model is that it uses only a magnetic braking system, and we would prefer it to be supplemented by a mechanical brake that could let it work in higher wind speeds.

Best Marine Wind Generator Buyer’s Guide

Marine wind generators are an excellent choice for sailboats that may not have a powerful enough generator to run all of the onboard electrical devices. However, they aren’t only made for sailboats, as some smaller motorboats may not have an efficient way of siphoning power from the engine for electrical implements.

Using a marine wind generator hooked up to a battery, you can run devices like your radio, onboard GPS, and you can even charge your phone. Marine wind generators are also a better choice than small generators or auxiliary power units since they’re smaller, quieter, and more ecologically friendly.

Important Features to Consider

Ease of use and ease of setup.

Wind turbines still require a certain level of knowledge on the part of the user, but as time goes by, they get easier to hook up and use. A wind turbine that’s designed to be as user-friendly as possible therefore overcomes one of the main hurdles that many buyers face when they consider purchasing them.

A marine turbine needs to be made out of suitable materials so that it doesn’t end up getting damaged by the elements while it’s mounted to your boat. Metals like aluminum and stainless steel won’t rust and therefore fail after a bit of exposure to water.

The material will also determine how heavy your wind turbine is. Too heavy of a turbine may adversely affect your boat’s performance and will certainly be more difficult to set up.

Frequently Asked Questions

Do i need to wire my marine wind generator myself.

Yes, in the vast majority of cases, you’ll need to hook up the generator to the battery that you’re using to store the energy, so you’ll need to have a basic idea of what you’re doing to get the system running.

Can I supplement my marine wind generator with solar panels?

Yes, you can wire your marine solar panels into your energy generation system on your boat, even coupled with your wind turbine. In fact, some wind turbines are even designed to work with solar panels straight out of the factory, without much modification on your end.

Other Products We Looked At:

Marsrock small wind turbine 400w.

Aside from that, there are plenty of intelligent design features like the copper brackets in the blades that will prevent you from accidentally damaging them by tightening them too much. The charge controller on this wind turbine is also relatively intelligent, cutting down the speed of the blades so that the power output is consistent.

One of our favorite things about this wind turbine is that it’s a lot more affordable than many of its competitors, but it’s still reliable and features the same 400W power output. While this wind turbine is a solid choice, it doesn’t exactly stand out in any particular area, so it couldn’t match our top five.

• Copper brackets in the blades keep them from cracking when fastened to the hub
• The blades are made of plastic reinforced with carbon fiber

The Master940 is the best marine wind generator available, and its only major downside is that it’s so expensive. If you’re not willing to spend so much on your marine wind turbines, the Happybuy Vertical Wind generator is available for a more reasonable price and can generate power regardless of the direction the wind is coming from.

If you’re trying to save even more money, and you’d rather opt for a more traditional type of marine wind turbine, Happybuy’s other 400W wind turbine is cheap, easy to set up, and much more reliable than its competitors.

We hope that these reviews have given you a good idea of what to expect from these marine wind generators.

Wind generators – buyers’ guide

After a flurry of recent technological developments, Duncan Kent compares the latest high-output wind turbines

Three-bladed rotors have become increasingly popular. Although early models were quite noisy, smart CAD-designed blades have considerably reduced the thrumming and whistling sounds by removing the turbulence around the blade tips. Furthermore, the use of more efficient, low-cogging (less initial friction) permanent-magnet alternators has also allowed blade speeds to be reduced, further limiting ambient noise levels.

AIRBREEZE £1,169.50

The Airbreeze is easy to assemble as everything is contained within the casing, requiring only a quick blade assembly before being ready to mount. It’s not the most powerful and can be a little noisy in high winds, but it’s very good value as you don’t need to spend money and time installing an external charge controller.

Verdict: Easy to assemble, mount and operate, but noisier and less powerful than some

ecopowershop.com

ECLECTIC ENERGY D400 £1,350

Although it’s fairly straightforward to assemble, it’s not made any easier by the sheer weight of the generator.

During previous trials it proved to be one of the quietest on test, started quickly and outputting an increasingly progressive rate of charge. It is also less prone to yaw from side to side than some, keeping head into wind to ensure a more stable output.

Provided its mounting can handle the loads, its sturdy build allows it to continue operating in very high winds, producing a staggering 50A+.

Verdict: Solidly engineered, very powerful and quiet. The flip side is it’s heavy and needs dump resistors

eclectic-energy.co.uk

LEADING EDGE LE-300 £649.95

The device is easy to assemble and light enough to carry in one hand. An integral rectifier produces a two-wire DC output and its efficiency has recently been improved with the fitting of stainless steel counterweights to offset the effects of pitching and yawing common on a yacht.

A run/stop switch is supplied that brakes the turbine by shorting its output. It can also be supplied with a dump load style regulator to prevent overcharging (£189.95).

The LE-300 is probably the quietest of all the three-blade models available, but it’s also one of the least powerful.

Verdict: Light and great value, but with a lower output than many of the others

leturbines.com

LEADING EDGE LE-450 £899.95

The alternator uses rare earth fixed magnets and has zero ‘cogging’, allowing the turbine to start quickly and to spin in the lightest of breezes. Furthermore, having five blades of advanced design allows the swing radius to be kept to a minimum and reduces wind noise noticeably, while its light weight allows it to be safely mounted on a mizzen mast or possibly even a stout spreader.

Verdict: Well designed, lightweight and good value, but needs manual tethering in over 35kt of wind

RUTLAND 914i £649.96

An optional multi-stage charge regulator is available, which has an on/off switch and LED charge status indictors. It can also accept and integrate solar panels up to 160W.

The surprisingly cheap HRSi regulator (£78.50) works electronically to gradually slow the turbine in high winds or near full charge situations, rather than using resistive dump loads.

The 914 is quiet in operation and quick to start generating in light winds. Well made, its heavy metal hub acts as a flywheel, giving it enough momentum to smooth out the pauses during brief lulls in the wind.

Verdict: Quiet and inexpensive, with a smart controller. Relatively low output

marlec.co.uk

RUTLAND 1200 £1,195.00

High rotation speeds and efficient alternator design results in plenty of raw power. Marlec’s latest smart HRDi charge controller (£155.95) continuously alters the rotation speed of the generator, slowing it down as the batteries become more charged. It also incorporates the latest Maximum Power Point Tracking (MPPT) technology to optimise all the available energy produced and Pulse Width Modulation (PWM), which enables multi-stage charging to keep the batteries topped up. Other features include dual-battery bank control, an input for up to 250W of solar panels and an optional remote digital display.

Verdict: Powerful, well-made and with smart regulation. Has a wide rotation diameter

SILENTWIND 400 £1,291.33

The Silentwind is heavier than it first looks, mainly due to its high output, permanent magnet 420W alternator. Recent (2016) upgrades include a boost feature in the generator and a lower start speed thanks to its ‘low cogging’ design.

Available in 12V, 24V and 48V versions, its three-wire AC output connects directly to a recently upgraded smart charge controller with solar inputs, an LCD display, integral brake switch and Bluetooth connectivity so the user can monitor their battery status and charge from a mobile device or laptop. Furthermore, the new controller (£410.42) now consumes only 20mA itself, rather than the 100mA of the old model.

Verdict:   High power output and a nifty Bluetooth smart controller, but all at a price

technicalmarinesupplies.co.uk

SUPERWIND 350 £1,528.75

The SCR Marine charge controller option (£384) has two independent outputs, for start and service banks, although it does rely on the rather crude method of dumping any excess loads to two large resistors, which can get very hot if the device is left running in a gale.

Despite having a slightly lower output alternator than some, in field tests this device gave a very respectable performance in wind up to 15 knots, and provided serious amps in higher winds up to 28 knots.

Verdict: Light, well made, quiet and powerful, but expensive and reliant on dump load regulation
