X-1 Ton is a 39 ′ 9 ″ / 12.1 m monohull sailboat designed by Niels Jeppesen and built by X-Yachts between 1983 and 1990.

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)

Winner of Int. 1 ton cup in 1986. (30.5’ IOR as of 1983) Production version with more interior amenities is X-402.

X-Yacht 3/4 and 1 ton

• Add to quote

Hello everyone, I wanted to ask if any of you guys have any experience racing or cruising with either an X-Yacht 3/4 ton or an X-Yacht 1 ton. What do you think about the boats and their performance? Have you ever raced any of them? When I contacted X-Yachts in Europe they didn’t have any information to send me on either boat. All responses will be greatly appreciated. Thanks  

Both boats are older, IOR designs that did well in Europe, racing IOR. Because of the IOR underwater shapes, they can be tricky to sail fast. I believe they are fractional sloops with pretty small jibs, so mainsail trim is VERY important. Hearsay relates that they are hard to sail to their PHRF ratings. This may be because they need to be sailed like a 420, at 110% from each of the 8 crew, all the ttime. Their beam and relatively small ballast (I believe they have cast iron keels, rather than lead) make crew weight necessary to hold them flat in any breeze. That said, the sail handling systems and rigging on X-yachts that I have seen have all been excellent . They''ve been given enough sail area to be able to move if properly attended to. They appear to hold up well and be well put-together. Layout and finish below have also been quite nice, though some of the earlier models (such as these) may be more stripped out below than others. You could do a lot worse, but line up a big list of good crew if you want to race and do well.  

I am quite familiar with the X Yachts 3/4 tonners. They were very well constructed and actually do reasonably well under PHRF. They were pretty spartan down below but so are most race boats. Like most IOR race boats they respond to tweaking up to a point and are quick to loose speed and slow to get it back. These were better mannered boats than many of their contemporaries. They are not the best light air boats but they seem to hold their own when a breeze fills in. I have always like the deck layout on these boats. An Annapolis based X-34 ton won the 3/4 ton worlds when these were comparatively new boats. I would also look at the Farr 33''s and the J-34 both of which are moderately competitive under PHRF. As to the One tonner, I looked at one of these when I was searching for my current boat. I thought that these were far more crudely constructed than the high quality X-boats that I had previously encountered. This particular boat was a real mess. There problems with the connections between the steel frame and the hull, and large sections of the boat showed stress cracking and other forms of distress. The hardware layout was a bit strange and really seemed to rely on a large skilled crew. I would suggest staying away the One tonners as they seem to be not as robust and not as competitive as the 3/4 tonners. If you feel that you must go the one tonner route, the two designs that seem to have remained competitive and held up pretty well are the Farr one tonners like the Garratt 40 and the Soverel 39''s. Respectfully, Jeff  

Thanks a lot Paul and Jeff for your very informative responses. I got more information from you guys than I got from months of researching on internet and contacting X-Yachts. I saw an X 3/4 ton and I liked the boat immediately. What stood out for me as well were the deck layout and the open transom. I really liked the way it was designed. I have never sailed either one to know how they sail. I have sailed a Soling, a J24, a J29, and a Frers 33. I think they might be more similar to the J24 sailing characteristics, but I might be mistaken. As for the One Ton I haven’t seen one from up close yet to be able to form an opinion. Thank you Paul for all your details regarding sailing the X 3/4 ton. I don’t think I will ever have 8 people as crew, I think we will be at most 5. I am fairly new to racing so I wanted an inexpensive boat as a first boat, but also a boat that I can take out with three people for a day sail. I also agree with you Jeff on the Farr 33. I saw one boat and I really liked the design and deck layout. They are a bit pricier though, around 10K more than the X-Yacht (YachtWorld website prices and listings) so that moved me away from the Farr 33. Any other boats that you guys might think of that fall in the same category as the X 3/4 ton, performance and price, that I should be considering? Do you also know of a different place other than YachtWorld that I could look for boat listings? Your responses are as always greatly appreciated. Spiros.  

When you start talking about older IOR style boats you are generally talking about boats that need pretty large crews for thier size. If they are set up where they can be end for end jibed they can be raced with as little as five people but to race them successfully they require a quite a bit of rail meat. Some of the better 33-34 IOR boats might include the J-34, Dehler DB-2 & DB-4 and besides the Farr 33, Farr also did a number of nice custom and semi-custom 3/4 tonners. Ericson also built a pretty quick Ron Holland designed 3/4 tonner. You see these boats through a very wide range of prices. When you talk about good older 33 foot PHRF race boats, the first boat that comes to mind would be the Soverel 33. Tartan 10''s are reasonable PHRF boats that do not need a huge amount of crew weight. Tripp 33''s are a bit fragile but they tend to be a little more expensive. If you can find a Soverel 30 they are bargain phrf racers. S2 9.1''s are good PHRF and MORC boats. If you want to get by with a 5 person crew Laser 28''s are very good boats. Jeff  

A couple other good PHRF boats in that size range would be the J-29, Kirby 30 (both ideally masthead rig) and J-30. Jeff  

Raced on an X3/4 ton and got destroyed in heavy air by both the Frers 33 and J29.  

I own a X-yachts 3/4 ton. Last year one of our sister ships from the club won the Western Lake Erie champion ships in one. We placed 3rd in our class. The previous owner of my boat has won in the Chicago NOOD, and twice in Key West, the second time with a reduced rating. This boat can sail with 5 crew no problem up to about 12 knots. After that you need the 8 or 9 you are allowed to hold the boat down. You still only need 4 or 5 who know what they are doing to sail it well. I our local races we race agianst a couple of j-33s, a Soveral 39 and a Henderson 30. The one boat is always in the 3. The other boat is generally mid way or better. I would also not that these boats are fast in heavy air. I can easily do 10+ knots dead down wind in 20 knots of breaze. That said, I really think it depends on the people sailing the boat. There are alot of good boats out there. The Soveral 33 and 30''s, Evelyn 32, J-33 and others. I have done an extensive search on race results. It turns out you can win with any boat. Some boats win more often. Some never seem to win. I have beaten boats that rate as low as 81 in PHRF with my 3/4 tonner boat for baot. I have had other owners of the same boat beat me quite soundly on handicap. My advice, find something you can win in, that you like the layout of, and practice, practice, practice.  

The MK II displaces 7260 and has 4840lbs of balast. The beam is 11ft. Main trim is important. 4 or 5 core crew needed. Total 8-9 when it blows but the rest are ballast. On the old boat we could not get 5 to come out all the time. On this boat I have rarely sailed with less than 6. We do twice as many races and still have crew for all of the races.  

Thanks to all of you for the great detail of information you have provided me with. Thanks!  

I own an old IOC 3/4 ton Camper nichiolson 33'' It wins lots of races here in the Carribean with minimal crew--Sometimes just me (a girl) and my 9 year old son! If you could find one of these boats i would snap it up. It also has a great cabin-we live aboard! Good luck in your search.  

From what aspect of the design is the term "one tonner" derived? There is a S&S 38'' aluminum one tonner offered for sale in my area and I was planned on having a look at her this weekend. She was built by Minnefords Yard in NY and won the admirals cup in ''73.  

It is a measurement formula for racing classes(like formula 1 with cars or 12meter boats with Americas cup race yachts). It has nothing to do with the weight or footage of the boat (or at least not in a clear and logical way) but takes about twenty + different and obscure measurments into acount in order to generate an overall rating. Go take a look at the boat. Sasha  

Hola buenas soy nuevo por aqui, soy propietario de un X one tonner MKII que sigue en carrera a dia de hoy, estoy muy contento ya que el año pasado hemos echo 1° 2° y 3° puestos en todas las regatas que participamos de orc3 , el barco tuvo un refit en el 2005 donde se reconfiguro la geometria del casco y se actualizo, por ese motivo sigue siendo competitivo. Si quieren verlo en accion en instagram @rasslimitone. Saludos [Translation by Moderator] Hello, good, I'm new here, I own an X one tonner MKII that is still in the race today, I am very happy since last year we have achieved 1st, 2nd and 3rd places in all the regattas that we participate in orc3 , the boat had a refit in 2005 where the geometry of the hull was reconfigured and updated, for that reason it is still competitive. If you want to see it in action on instagram @rasslimitone. Greetings

Konstruktorens kommentar: Udviklingsarbejet med X-l Ton begyndte faktiske allerede i 1983, idet X- Yachts som det forste vcerft i verden, begyndte en seriebyg-ning af X-3/4 Ton i materialer som unidirectional S-glas, unidirectional kulfiber samt unidirection kevlar 49. Ved hjcelp af disse hej-teknolo-giske materialer har det vceret muligt at reducere skrog og dceksvcegten til et absolut minimum. Erfaringerne med denne byggemetode har vceret 100% positiv.

An attorney who helped acquit missing tech tycoon Mike Lynch among those feared dead in superyacht disaster

• A yacht belonging to British tech executive Mike Lynch sunk off the coast of Sicily.
• Christopher Morvillo, who helped Lynch win acquittal at a recent trial, and his wife are missing.
• Morvillo, a former federal prosecutor, worked on high-profile corruption cases.

Among those missing and feared dead in the aftermath of the sinking of "Bayesian," a sailing yacht linked to British technology magnate Mike Lynch , are Lynch's attorney Christopher Morvillo and Morvillo's wife, according to a colleague. Lynch was reportedly on a cruise with friends and coworkers, including Morvillo, to celebrate his acquittal after facing prosecution for financial fraud related to the sale of his company Autonomy to Hewlett-Packard in 2011. Lynch and his 18-year-old daughter, as well as two others, are still missing.

Gary Lincenberg, an attorney who represented Lynch's co-defendant Stephen Chamberlain in the high-profile fraud case that recently ended with the acquittal of both men, said Morvillo and his wife "are presumed to be passed away" after the yacht went down near Sicily.

He said the news came shortly after he learned that Lynch's codefendant Chamberlain was killed, struck by a car while jogging on Saturday.

"In the course of 48 hours, I can't process what has happened, but both of our clients, as well as Chris and his wife, are gone," Lincenberg told Business Insider.

Lincenberg said in a follow-up email that Chamberlain "was a courageous man with unparalleled integrity" and that his acquittal preserved his good name, which would live on through his family.

Morvillo's law firm, Clifford Chance, didn't immediately reply to a comment request on Monday. One of Morvillo's family members declined to comment.

Before going into private practice, Morvillo was a federal prosecutor in Manhattan until 2005. He worked on several high-profile corruption cases and comes from a family of well-known New York white-collar attorneys.

Another attorney at the firm, Ayla Ronald, is reportedly among those who survived the yacht's sinking.
