Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

About the Harbor 20

Built by the w. d. schock corporation.

www.wdschock.com

CLASSIC GOOD LOOKS – The W.D. Schock Corp. design team has deftly blended the beauty of traditional topsides with the efficiency of a high performance, modern rig and underbody to create an up-to-date day sailer. The graceful and distinctive lines of this Harbor 20 stand out in contrast to the many “look-alike” sloops on the market. The nice thing about classic is that it always looks right and never goes out of style. Modeled after the famous Herreshoff design, this new classic will turn heads in any harbor or yacht club, and provide each owner the permanent reward of a boat that’s always a pleasure to view.

COCKPIT COMFORT – The cockpit is where you live on a day sailer, and special attention has been devoted to maximizing this cockpit’s space, comfort and convenience. The seat and backrests are curved and angled to follow natural body contours. The two ice chests are within easy reach, secured by chocks and shaded by the cuddy. The seat lockers are cavernous, and the engine well doubles as an enclosed storage space. Small children are protected by the cuddy and the cockpit coaming, and there’s enough length and width to the seats to allow adults room to stretch out for a nap. Six plus adults, or the whole family can relax in comfort and electric motor can be easily deployed.

STABILITY & SINGLEHANDED EASE – By placing a significant amount (900 lbs.) of lead ballast down low, in a bulb, on a seaworthy hull, Shock has achieved an unusually steady craft with no bad habits. All lines are set up to lead to the cockpit so that one person can handle everything. The furling jib is self tacking and self vanging with the patented Hoyt Free Standing Boom. The fully battened mainsail is non flapping and powerful, and stacks itself safely between the lazy jacks. A special reefing set up allows one person to reef the main in less than 20 seconds – without leaving the cockpit. The Harbor 20 can handle a crowd comfortably – but it can also be a very satisfying single hander, so you don’t have to line up crew for what should be the simple matter of “going sailing.” These features are incorporated in one design class which is ideal for yacht club use because the need for skilled crew (or any crew) will be minimized.

PERFORMANCE UPWIND & DOWNWIND – You’d expect a modern sloop to sail well to windward, and the HARBOR 20 does not disappoint, pointing high and footing as fast as any similar sized day sailer on the market, without any need for hiking. This boat has a beautifully balanced feel that makes it pleasurably responsive and supremely easy to steer and maneuver. Downwind – where most sloops suffer the slows from non-functioning jibs – is where this boat comes alive. The jib boom keeps the jib out on all courses, and acts as an automatic whisker pole to wing out the jib. So while other jibs slat uselessly about off wind, the HARBOR 20 jib is an easily controlled, fully active drive unit on all courses – giving you full sail power, on all points of sail. You’ll be surprised how making the jib work full time adds to sailing pleasure and performance, and obviates any need for genoa or spinnaker.

TOP QUALITY CONSTRUCTION by W.D. Schock

For over 55 years the W.D Schock Corp. has set the standard for quality high performance sailboats. During their long history in the boat business, Schock has built over 70 different designs, including the Santanas Schocks, Thistles and numerous other popular one design sailboats. Like all Schock sailboats, the Harbor 20 is 100% hand laid up fiberglass and are engineered and built to yield maximum strength and rigidity. Their reputation for quality and service is well established.

A SMALLER BOAT THE WHOLE FAMILY CAN ENJOY – Today, most families can’t afford a large, one purpose racing boat that only one member really enjoys. And many older couples find they no longer need the trouble and expense of a large cruiser that sits idly at the mooring most of the summer for lack of crew. So here’s a boat that’s ready to go in minutes, suitable for one person or six, and it doesn’t require a major commitment of time or money. After all, the fun of sailing is more related to the ease and frequency of use than the size or expense of the boat. The Harbor 20 represents a new alternative, a classy day sailer that allows sailing to fit sensibly into modern lifestyles. Here is a boat whose stability and responsiveness will encourage you and your family to sail more often, and the One Design feature opens up simple, friendly, class competition on the race course. Safe enough to take along the kids, and simple enough to teach them to sail, the nimble Harbor 20 will please all ages.

LOA 20′ BEAM 7′ LWL DRAFT 3’6″ DISPL. 1800 LBS. BALLAST 900 LBS. SAIL AREA 232 S.F.

FEATURES AND BENEFITS OF THE HARBOR 20

Sailing Characteristics – The bow of the Harbor 20 has a fine entry for slicing through waves. The stern carries enough beam that the boat rides down waves nicely. The lead in the keel is concentrated in the lower half of the keel. The low center of gravity, with a 50% ballast-to-displacement ratio, combines with the ample beam to make an incredibly stiff and stable boat.

Construction – The hull is hand laid up mat and roving fiberglass. The resin is applied by brushes, rollers, and squeegees and is carried through hoses. Schock does not use a wet-out system, which sprays the resin into the fiberglass. They feel this system opens the door to potential osmotic blistering.

All bulkheads are tabbed into the hull for maximum strength. The bow is strengthened by a liner that is bonded to the hull on all surfaces. The bow structural support system includes an air tank, two bulkheads, and two platforms for ice chests. The keel grid is made of fiberglass and is bonded on all surfaces to the hull, spreading loads evenly. The keel grid incorporates two platforms for battery storage. This provides a place, both port and starboard, that is low and out to the sides, to strap down batteries, making the best use of their weight.

The hand laid up balsa-cored deck is bonded to the hull with a “shoebox” hull-to-deck joint. The deck is light and all one piece.

Cockpit – In the cockpit, at the forward end of each bench seat are two hatches that provide access to the batteries for the electrical system and extra storage. The cockpit floor holds three hatches to allow access to the sump, the electric bilge pump, the keel bolts, and the lifting eyes. The motor control panel for the electric motor is located halfway aft in the cockpit on the starboard side. This is the perfect location to reach the throttle while sitting at the tiller. The seat backs meet the seat bottoms, closing off the gap that is often found between the coaming and the seat. The seats are deep and wrap all the way around the aft section of the cockpit. The cockpit easily seats seven adults, while actually sailing . . . not just while tied to the dock. The aft lazarette contains the electric motor. The motor is mounted on an arm that rotates out and over the starboard gunwale. The deployment and retraction is assisted by blocks and line. Stowing the motor in this way keeps the prop from dragging in the water. The motor will push the Harbor 20 at about five knots without noise or smelly fumes. A charger is built into the cuddy on the port side. Just plug the boat in when done for the day. No more fuel docks, no noise, and no more rocking the boat when the wind dies.

Rig – The Harbor 20 rig comes with a roller furler for the jib, a Hoyt self-tacking jib boom, and lazy jacks for the main. The self-tacking jib makes single-handed sailing much easier, especially in tight quarters. It also allows for a much less experienced crew.

The sails that have been designed for the Harbor 20 are made of durable 6 oz. sailcloth. The main is equipped with full battens to further extend its life. The roller furling system on the jib and the lazy jacks make rigging and sail stowage a snap. Most owners leave their sails rigged and ready to go for the duration of the sailing season. Additionally, the lazy jacks prevent the boom and sails from falling all over everyone in the cockpit. When the sails can be put away so quickly, docking is amazingly easy.

The shrouds and stays are “Rigger’s Choice” 1 x 19, the highest quality stainless available. The running rigging is color-coded New England Rope Sta-Set. All hardware is Harken. The sail controls are led under deck to a shelf located on the aft edge of the cuddy and are labeled for easy identification. The contents of the shelf include the following: jib sheets, jib sock halyard, jib furling line, jib winger, jib outhaul, cunningham, main halyard, reef, and lazy jacks. Above the shelf is an 8:1 boom vang. The boom contains an internal outhaul. The backstay adjuster is lead under deck and into the cockpit. The mainsheet is adjusted from a cam swivel with a ratchet block located on a barney post. This leaves the access fore and aft in the cockpit clear. The traveler is located on the aft coaming of the cockpit. The mast is deck-stepped and can be equipped with a mast hinge. The rig is extremely simple, yet at the same time gives the trimmers a great deal of control over sail shape.

Strictly One-Design – When the Harbor 20 was used for the Championship of Champions, the competitors remarked over and over again that they had never competed in a round-robin with such undeniably equal boats. The competitors ranged in age from14 to 70. Class rules do not allow hiking, or even sitting on the rail. Greg Fisher, chairman of the event, called the Harbor 20 “a strict one-design that is both well balanced and simple to sail.” This places the emphasis on good boat handling and superior tactics rather than on athletic ability.

How the Harbor 20 came to be…..

On a beautiful Thursday evening about fifteen years ago, a group of seven salty sailors at the Newport Harbor Yacht Club in Southern California were sitting in the bar wondering why so few of the yacht club members were sailing. This got them to dreaming about the perfect boat. One that would get husbands and wives, families and friends back on the water.

After many more discussions on this topic, the salty seven came up with the perfect solution. A brand new 20-foot keel boat now known as the Harbor 20.

Each of the guys in the group had been an extremely competitive sailor in his day, but found himself sailing less each season. They had raced boats like the International 14, Star, Thistle, Etchells, Santana 20, Snipe, and Lido 14 but at 50+, they were no longer up to the physical requirements of these boats. And the hassle of racing larger boats had become a huge obstacle. The whole scenario of making twelve calls to get a crew of eight or nine together for a weekend race had definitely lost its appeal.

The more the guys talked, the more they realized how much they missed sailing and one-design racing. Surely there was a sailboat out there that could get the older sailors back on the water racing competitively and also get sailors of all ages out sailing with their families.

In the “good old days”, sailing had been a lifestyle. Generations of families had focused their summertime activities around yacht club events. But all of this had changed as dozens of new leisure-time activities emerged to divert their attention. The number of entries in the racing events was dwindling, and many of the boats in the boatyard sat idle for most of the year.

The group that met at the bar that day set out to change this. The man with the vision was Arthur Strock, a renowned architect with a passion for detail. He had a beautiful power boat but hadn’t entered a sailboat race in years. Recognizing that there were a lot of other sailors just like him, he set out to find a sailboat that would get Newport Harbor Yacht Club members back into sailing. He spent two years going from builder to builder, and he looked at daysailers and small racing sailboats all over the world.

In the end, he decided that the perfect boat simply did not exist. He kept detailed records of his search and compiled a 30-page document describing the boat that would be perfect for the job.

As Arthur did his homework, he continued to meet with the guys from that casual meeting at the bar. They were all staff commodores with outstanding racing credentials who definitely understood the importance of getting the members back into sailboats.

One of the members of that group was Tom Schock, past NHYC commodore, avid sailor, and owner of W. D. Schock Corp. Tom recognized the challenge faced by the yacht club, and he knew that it was a problem being faced by many other yacht clubs. He also knew that the future of sailing depended on finding new ways of making the sport more attractive. Junior programs were being enhanced to attract children to the sport, and exciting new high performance racing sailboats were being designed to entice young athletes, but nothing was being done to keep older sailors and busy young executives from abandoning the sport.

Based on Arthur’s study, the group zeroed in on the Criteria for their new design. They knew that the boat would need to be . . .

  • A beautiful, timeless design
  • Comfortable & efficient
  • Easy to sail whether sailing single-handed, double-handed, or with the whole family
  • Hassle-free
  • Fast & competitive
  • Fun for one-design racing
  • Perfect for daysailing with the family
  • And really easy to maintain

The Answer –The Harbor 20 – A 20-foot keel boat with a large cockpit and a self-tacking jib.

Another important member of the group was Steven Schock, a professional Engineer and Naval Architect with a lifetime of sailing experience. Steve designed the boat, focusing completely on the Criteria.

As a result, the Harbor 20 has a thoroughly modern and fast hull shape. The cockpit is huge. And the boat is equipped with things like cushions and the roller furling self-tacking Hoyt jib boom that makes it comfortable, efficient, and easy to sail.

The first Harbor 20 was launched in April of 1998. Within twelve years there were about 150 Harbor 20s sailing in Newport Beach. About 35 of these Harbor 20 owners actively race their boats, which means 115 Newport sailors love to daysail. Most of these daysailers join the class association so they can enjoy the parties, seminars, and lots of other special non-race sailing events. And the racers find the competition exciting enough to entice them onto the racecourse for Twilight racing five evenings a week during the spring and summer months.

There are now over 325 Harbor 20s sailing throughout the United States, Canada, Chile, and Australia. The Harbor 20 has definitely put families back on the water. It has also gotten husbands and wives back into the same boat. Young dads are racing with their children, and grandparents are sailing with their grandchildren. During this year’s annual Baldwin Cup Team Race at Newport Harbor Yacht Club, Jon Pinckney, one of Newport Harbor’s finest sailors, commented that “the Harbor 20 saved sailing at Newport. It has brought hundreds of sailors back into sailing.” Though certainly not in the 50+ category, Jon and his wife Gale are regulars on the Harbor 20 racecourse.

The boat is fun and easy to sail but definitely competitive. The design eliminates any advantage where crew weight and strength are concerned. Winning a Harbor 20 regatta depends entirely on the skill of the skipper. The Harbor 20 is perfect for teaching our children to sail. It is also perfect for taking friends for a delightful afternoon sail. All of the sail control lines are lead under deck to a console in the cockpit, so the lines are within easy reach for the skipper and crew. There isn’t a winch on the boat – there is no need for one.

The cockpit is 9 feet long, and you sit inside the cockpit – not on the deck. The boat comes equipped with two ice chests, and the class rules require that you race with cockpit cushions. It takes just five minutes to get the boat ready to sail. You just remove the cover and jib sock, raise the main, and unfurl the jib. At the end of the day, a clever custom-built electric motor will get you back to the dock. The motor pushes the boat along at about 4 knots. It is clean and quiet and is mounted on a special bracket that rotates out of the lazarette.

Plenty of options are provided to make the Harbor 20 fit any sailing style, and the boat is definitely easy maintenance. The Harbor 20s are generally kept in the water, and the only piece of wood is the tiller. The forepeak is a one-piece fiberglass liner. The floorboards, hatches, etc. are fiberglass. Even the floor timbers are fiberglass – no wood to decay over time. The keel is a fiberglass shell with lead and epoxy poured into the shell.

At the end of a day of sailing, you just roll up the jib, fold the main onto the boom, plug in the electrical power, and put the covers on. The boat sits ready and waiting for the next time you have a few minutes to spend sailing.

Harbor 20 Fleet 5

The first Harbor 20 was launched in April of 1998. Within twelve years there were about 150 Harbor 20s sailing in Newport Beach. Today there are over 400 Harbor 20s sailing throughout the United States, Canada, Chile, and Australia. Fleet 5 in Annapolis has over 30 boats and regularly has about 20 boats at the start of the Wednesday Night Racing series and Class Championship and over 25 for its three charity regattas (see Charity ).

The Harbor 20 was designed with simplicity in mind and a competitive spirit at heart, whether you’re sailing upwind or downwind. For example, a roller-furling fractional headsail and self-tacking club boom help the Harbor 20 practically sail itself upwind. When running wing-and-wing, the club boom acts as a vang, effortlessly holding out the jib. The full-battened main stows neatly on the boom using lazy jacks. Finally, the control panel just behind the mast is centralized convenience at its very best. So, when you’re ready for the wind and sea, so is the Harbor 20.

Review of Harbor 20

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

The Harbor 20 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The boat can enter even shallow marinas as the draft is just about 1.07 - 1.17 meter (3.51 - 3.81 ft) dependent on the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Harbor 20 is 2.30, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.5 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Harbor 20 is about 73 kg/cm, alternatively 413 lbs/inch. Meaning: if you load 73 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 413 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is Displacement Length Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 12m 2 (129 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

Hi-I'm looking at a 1998 Harbor 20 in a couple of days. Can anyone offer any advice on what to look for specifically? Thanks in advance.  

rgranger

I googled Harbor 20 reviews and got a fair number of hits. It is a smart looking boat. Should be really fun for a day sail or race around the marks.

SBO Weather and Forecasting Forum Jim & John

  • old sails (need too be replace - this is the boat's power source),
  • aged rigging (another consumable),
  • possible blemishes on the deck/hull (inspect for water intrusion - repair issue),
  • hardware that my not have been serviced (inspect, repair/replace).

Our sailing club had a few Harbor 20s for a few years. She is a nice sailing boat, and pretty comfortable, but with a very low freeboard, the boat was very wet. Miss seeing or mis-judge a powerboat wake, and you routinely would get white water down decks and into the cockpit. I'd consider one only for enclosed sailing areas without a lot of powerboat traffic. After two years, they were sold off...

Harbor 20 Class Association

In 1995 a group of local sailors comprised of Arthur Strock, Phil Ramser, Bill Palmer, Pete Pallette, and Grant Baldwin began to realize the need for a day sailing/racing boat that was suitable for sailors who have a very broad range of skills and experience, have a desire for sailing with friends and family, and have a desire for a boat that is both forgiving of error and rewarding of excellence.  They wanted a boat that would appeal to men and women ranging in ages from 30 to 80+ years, have an ease of boat handling either solo or by a husband and wife crew, yet be large and comfortable enough to accommodate a family outing.  It was an equally important goal to develop a good, one-design fleet racing program that would be encouraging and inclusive of a broad range of age and skill levels, and at the same time, develop a strong and active social program.

The committee first defined the program and then the boat.  Specifically, the following boat criteria were established:

  • Competitive with a very broad range of age, crew weight, physical strength;
  • Easily single-handed;
  • Accommodating of six adults in a day sailing mode;
  • Fast in light air yet manageable in a blow;
  • Easily maintained;
  • Wet sailed  (thus avoiding hoists and trailers);
  • Reasonably priced;
  • Good looking.

After an extensive search of the national market, no suitable boat was found that met all criteria.  The group then began to think seriously about a new design and asked Tom and Steve Schock of W. D. Schock Corp. to propose a design that would meet the above criteria at a competitive price.

Tom and Steve were able to meet the criteria, both functionally and aesthetically.  The team effort among the builder, the naval architect, and the user – the fleet committee – resulted in the Harbor 20.  Its sail area, displacement, and waterline length make it a very large 20 footer and is accommodating of a broad range of uses and users.

The first Harbor 20 was launched in May of 1997, and true full production began a few months later.  Initially,

there was skepticism about the electric auxiliary, but now virtually all of the boats have them.  The addition of the auxiliary motor actually provides the functional equivalent of two boats – sail boat and bay cruiser. Importantly, the Harbor 20 fleet has developed an organizational, operational, and social format that appeals to and supports all of its members, racers and day sailors alike, regardless of skill level; it has a strict set of one-design rules that includes sail purchase restrictions to ensure economy and retention of value.  The Harbor 20 program and boat have indeed been successful.  If numbers on the water are an indication, the Harbor 20 will continue to serve sailors’ needs as a competitive, durable, and functional bay boat for a long time to come.

Age Limitations On Boating

If solo on a vessel – No person under the age of 16 years old shall operate a vessel powered by a motor greater than 15 HP, or a sailing vessel greater than 30 feet in length, unless it’s a dingy used directly between a moored vessel and the shoreline or between a moored vessel and another moored vessel.

If with other passengers – No person 12,13,14 or 15 years of age shall operate a vessel with greater than 15 HP engine or sailing vessel greater than 30 feet, unless accompanied by a person who is at least 18 years of age and who is attentive and supervising the operation of the vessel.

Exceptions:

  • A person operating a vessel as a performer in a professional exhibition.
  • A person engaged in a regatta, vessel race or water ski race.

Local Ordinances

Ventura Harbor is regulated by Ventura Harbor Ordinance 44 which was adopted by the Board of Commissioners in June 2002.

Kayak/Stand Up Paddle Boarding Rules

A personal floatation device (PFD) needs to be aboard or worn for every person.

Please do not travel between the riprap and the marina especially under the gangways. Harbor Patrol suggests visitors stay to the side of the channels.

  • Stand-up paddleboarding while surfing does not require a PFD.

The Harbor Cove beach is a still water beach located across from the National Park Service. The City of Ventura provides lifeguard services at the beach during the summer. It is illegal to swim anyplace else within Ventura Harbor.

The areas north and south of the harbor are posted as being hazardous for swimming. Lifeguard services are not provided. Rip currents and the jetties make it very dangerous to swim or even wade in either area. A memorial to Harbor Patrol Officer Paul Korber sits at the base of the South Jetty. He died March 15, 1998, while attempting to rescue a family of three that had been swept to sea by the rip current.

Safely Approaching Ventura Harbor From Sea

Due to improvements in the design of the harbor entrance and frequent dredging, it has never been safer to enter and exit the harbor. Still, some “local knowledge” will be helpful.

Enter or exit only via the main entrance, between the two jetties. The area behind the breakwater is designed as a Sand Trap and is subject to severe shoaling.

The entrance buoy “2VU” is located approximately ½ mile off the entrance. The prudent skipper always keeps this buoy to the starboard when entering. This keeps him or her away from the mouth of the Santa Clara River which lies ½ mile south of the harbor entrance. As one of the largest naturally running rivers in Southern California, the Santa Clara River provides a tremendous amount of sand to the local beaches. Unfortunately, this can create heavy surf conditions far out to sea.

A brief history of boating, shipping accidents off the coast of Ventura County

Portrait of Mike Harris

The waters off the coast of Ventura County have experienced numerous boating accidents – some fatal – over the years. This week's fire aboard and subsequent sinking of the Santa Barbara-based Conception counts among the region's worst.

As of Wednesday, 33 bodies had been recovered, but 34 passengers in total are presumed dead from the dive boat blaze early Monday near Santa Cruz Island.

Here's a list of some other local maritime incidents:

  • 1853: a wooden steamer, the Winfield Scott, sinks, leaving 400 passengers stranded on Anacapa Island.
  • 1952: The Del Rio, a commercial fishing vessel, catches fire and sinks off the coast of Anacapa Island.
  • April 13, 1970: The La Jenelle, a 465-foot-long luxury liner, sinks off the Oxnard coastline. No fatalities.
  • April 17, 1997: Three men die when their Ventura-based commercial fishing boat, the Lindy Jane, sinks off San Nicholas Island.
  • Jan. 3, 1999: One man dies and another is presumed dead after their 40-foot outrigger canoe sinks in frigid waters near Channel Islands Harbor.
  • Dec. 23, 2005: A Camarillo teen presumably drowns when the 14-foot open boat he is riding in with two siblings and their father capsizes near the mouth of the Santa Clara River between Ventura and Oxnard.
  • July 10, 2006: Two men die when the commercial fishing vessel they are on capsizes.
  • Aug. 20, 2011: Two people are injured - one critically - as their boat is docking in Port Hueneme.
  • March 10, 2012: Four passengers die when their 24-foot outboard motor-powered boat capsizes near Santa Cruz Island.
  • July 29, 2015: A commercial fishing vessel, the Ferrigno Boy, strikes the Ventura Harbor Boatyard travel lift pier, causing significant damage to the pier, but no injuries.
  • Oct. 21, 2015: Three people safely evacuate a 36-foot burning boat between Santa Cruz and Anacapa islands. The boat sinks.
  • Jan. 10, 2016: A commercial fishing vessel, Day Island, runs aground on Ventura Beach after the captain falls asleep while operating the boat. No injuries.
  • Febr. 26, 2016: One man dies after a commercial fishing vessel, Miss Jacinda, sinks 17 miles northwest of Ventura.
  • April 10, 2016: A 50-foot fishing vessel hits the south end of the jetty at the mouth of Ventura Harbor, partially sinking. Three people are rescued from the boat, none with serious injuries.
  • May 31, 2016: A 30-foot fishing vessel runs aground at Channel Islands Harbor.  No injuries.

Though not a maritime accident, on Jan. 31, 2000, Alaska Airlines Flight 261 crashes off the Ventura County coast, killing 83 passengers and five crew members.

This is not a comprehensive list. If you know of any other local boating accidents that should be added to it, please contact Star staff reporter Mike Harris at [email protected] or 805-437-0323.

  6. The Harbor 20

    The Harbor 20 was designed with simplicity in mind and a competitive spirit at heart, whether you're sailing upwind or downwind. For example, a roller-furling fractional headsail and self-tacking club boom help the Harbor 20 practically sail itself upwind. When running wing-and-wing, the club boom acts as a vang, effortlessly holding out the jib.

  13. Review of Harbor 20

    The Harbor 20 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel. The boat can enter even shallow marinas as the draft is just about 1.07 - 1.17 meter (3.51 - 3.81 ft) dependent on the load. See immersion rate below.
