The J Class

J Class yachts were originally built to the specifications of the Universal Rule. The J Class really represents the golden age of racing for the America’s Cup in the 1930s when this Universal Rule was used as the determining measurement system.

About the Class

Designers had to produce a J Class yacht which had a rating of between 65 and 76 feet. That was not the length of the boats but a product of the limiting factors of the rule’s equation. Any of the determining factors such as length, displacement or sail area could be changed but such changes required proportionate change in other factors to compensate. This allowed them to be raced on a level basis. Stability was not taken into account. Limits were set on measurements for waterline length, draft, freeboard and so on.

The three original surviving Js - Velsheda, Shamrock and Endeavour - have been refitted for worldwide cruising and racing. Their displacements have increased and the yachts no longer rate as a J under the Universal Rule definition, with the exception of Shamrock V, which was the smallest of the Js.  

In total nine J Class yachts are active now with six replicas having been built since 2003; Ranger, Rainbow, Hanuman, Lionheart, Topaz and Svea.

The J Class Association

The J Class Association (JCA) was founded to protect the interests of the Class, present and future. Among its responsibilities it monitors and agrees the veracity of designs to which new replica boats can be built to, the build materials and specifications, which since Hanuman and Lionheart have included aluminium alloy.

It’s objective is to keep the J Class fleet and races alive and to encourage new build yachts (replica builds from original plans) to join the Class. The intent is to race the surviving Js, new existing Js, and potential new replica Js together in such a manner that has a fair handicap, to ensure that.

The Rules are kept as short and simple as possible, in order to meet the objectives.  The Rules are written in the proper gentleman’s spirit, not to be bypassed to gain advantage, which is not in the spirit of the Class.

The original late 20th Century refits of the three surviving Js were used to help respect the tradition and guide the structure of these rules.

how to spot the J Class yacht fleet

The ultimate J Class yachtspotter’s guide

The J Class is undoubtedly one of the most beautiful and powerful classes of sailing yacht in the world. An original fleet of 10 was constructed in the 1930s for the purpose of competing in the America’s Cup, but in a sad twist of fate, only a few were able to survive the cull for metal during World War II. Some were later salvaged from the scrapheap and rebuilt as modern-day racers while others were constructed as replicas by owners who admired their classic lines and racing credentials. Nine J Class sailing yachts race today but could you tell an original from a replica? Could you identify which J Class yacht is which by its sail number? Here's an essential guide to the J Class fleet... 

Sail number : JK3 Length : 36.5m Year of build : 1929

With more than 80 years under her keel, Shamrock V is one of the most historic sailing yachts still afloat today having been built by Camper & Nicholsons in 1929. Her current owner bought Shamrock V in March 2016 and in the process inherited a legacy. This 36.58 metre is the original J Class yacht and the only one with a wooden hull to have survived to the present day. Her original owner Sir Thomas Lipton is remembered as the lovable loser of the America’s Cup , having unsuccessfully challenged on five separate occasions between 1899 and 1930, taking each defeat with characteristic good grace.

Sail number : JK4 Length : 39.56m Year of build : 1934

Endeavour was launched by Camper & Nicholsons in 1934 and is hailed as one of the most iconic sailing yachts in the world . Commissioned by Sir Thomas Sopwith, this 39.56 metre design was a highly rated contender heading into the 16th America’s Cup, but ended up losing 4-2 to Harold S. Vanderbilt's Rainbow . However, this is widely acknowledged to have been more down to tactics than design or performance. After spending the better part of 50 years languishing in obscurity, she was meticulously restored by Dutch yard Royal Huisman in 1989 and was most recently refitted in 2011 by New Zealand yard Yachting Developments . 

Sail number : JK7 Length : 38.5m Year of build : 1933/2016

Velsheda was built in steel in 1933 for WL Stephenson, the chairman of Woolworths in Britain, and named after his three daughters Velma, Sheila and Daphne. This 38.5 metre yacht is the only original J Class not to have been built for the America's Cup . Between 1937 and 1984 she languished in a mud berth on the Hamble River before scrap-metal merchant Terry Brabant rescued her and chartered her on a shoestring budget with no engine, mostly in the Solent but also in the Caribbean. In 1996 she was purchased by Dutch fashion entrepreneur Ronald de Waal who commissioned Southampton Yacht Services to rebuild her. Since then de Waal has raced her extensively .

Sail number : J5 Length : 41.55m Year of build : 2003

Ranger is a 41.55 metre replica of the J Class yacht of the same name, which was built for the 1937 America’s Cup by a syndicate led by railroad heir Harold Vanderbilt. Starling Burgess and Olin Stephens had been asked to produce eight sets of lines and the one selected as most suitable for the conditions expected off Newport, Rhode Island — design number 77C — was one of Burgess', although Stephens later helped with some refinements. Known as 'The Super J', the original  Ranger comprehensively beat Endeavour II in the Cup and won all but two of the other 33 races in which she competed that year. She never sailed after that and was broken up in 1941. With the design optimised by Reichel-Pugh , the new Ranger was built in steel — true to the original but unlike the subsequent modern Js — by Danish Yachts in 2003 for an American owner. 

Sail number : JK6 Length : 42.1m Year of build : 2009

The reincarnation of the 1937 launch Endeavour II , Hanuman was launched in 2009 by Dutch shipyard Royal Huisman . This 42.1 metre yacht features her predecessor’s original Charles E. Nicholson design, while the underwater geometry is courtesy of Dykstra Naval Architects . After completing the rebuilds of Endeavour , Shamrock V and Velsheda , Hanuman was Dykstra's first J Class new build project. Commissioned by serial yacht owner Jim Clark , Hanuman is named after the son of the Hindu wind god, which it flies on its spinnaker, and her regatta performances have backed up this name. She took first place at the 2017 St Barths Bucket , which saw six J Class yachts battling it out on the high seas.

Sail number : JH1 Length : 43.4m Year of build : 2010

Lionheart is based on Burgess and Stephens design number 77F, which was one of those rejected in favour of 77C for the 1937 America’s Cup. However, after extensive research by Hoek Design Naval Architects , 77F was considered to be the best set of lines for the variety of racing conditions likely to be encountered at regattas around the world today. Lionheart was built in aluminium by Bloemsma and Claasen Jachtbouw in Holland, and was launched in the summer of 2010. Her first owner's business commitments forced him to sell her and she was purchased in mid-2011 by Dutchman Harold Goddijn, the founder of Tom Tom. At 43.4 metres overall and with a stunning 17 metre overhang, she is the second longest J afloat. Lionheart became the first Hoek-designed J to hit the race course and made its debut at the Superyacht Cup in Palma.

Sail number : JH2 Length : 39.96m Year of build : 2012

The original Rainbow was launched in 1934 at the Herreshoff yard in New England after a mere 100 days under construction and went on to win the America’s Cup in the same year. However, she was requisitioned during World War II and eventually scrapped. The modern Rainbow  is an altogether more high-tech affair — built at Holland Jachtbouw in 2012 as the fourth of the new generation Js. She was built for an experienced sailing yacht owner to a design by Dykstra Naval Architects and is the first J to be fitted with a hybrid propulsion and power system. Rainbow is currently listed for sale . When heeled over, its red underside is a dead giveaway for yachtspotters out there.

Sail number: J8 Length : 42.62m Year of build : 2015

Topaz is based on an unbuilt 1938 design by Frank C Paine, the son of the three-time America’s Cup winner General Charles J Paine. Her modern aluminium incarnation measures 42.62 metres and was launched by Dutch yard Holland Jachtbouw  in 2015. Hoek Design Naval Architects, who styled Topaz inside and out, describe her as “a good all-round performer”. She was the longest J by waterline length at the time of her launch but was later dethroned by Svea .

Sail number : JS1 Length : 43.6m Year of build : 2017

The newest and longest member of the J Class fleet, Svea was launched by Dutch yard Vitters in February 2017 measuring 43.6 metres. Her design by Hoek Design Naval Architects incorporates an integrated traditional long keel from the original 1937 drawings by Swedish designer Thore Holm, which were unearthed by yachting historian John Lammerts van Beuren. However, the designers have brought the 75-year-old design right up-to-date with an aluminium hull and 53.75 metre carbon fibre main mast. As a result, Svea displaces just 182 tonnes — two tonnes less than Hanuman and six tonnes less than Ranger .

Story of the J-Class Yachts:

The J-Class was adopted for America's Cup competition in 1928, looking forward to the next regatta in 1930.  The Class itself, though, dated back to the turn of the century when the Universal Rule was adopted though no J-Class yachts had yet been built.

The Rule used a yacht's various dimensions to calculate an equivalent rating in feet.  Boats of equal rated lengths could then race against each other directly without making other allowances for time or distance sailed.  Even though one yacht might have a longer length or another yacht a larger sail area, their overall configurations had to produce a rated length that met the Universal Rule for that class. Boats in Class J, more commonly today termed J-Class yachts, were the largest constructed under the Universal Rule.  The Rule actually includes provisions for an even larger type of boat, the I Class, though none were ever built.  Inquiries made in the 1930s for a Defense in the smaller K Class were rejected.

The J-Class were the first yachts in an America's Cup match to be governed by a formal design rule.  Previous defenders and challengers were only restricted by minimum and maximum lengths set forth in the Deed of Gift.  Sir Thomas Lipton, challenging in 1930 for the fifth time, had held earlier discussions with the New York Yacht Club in hopes of adopting the Universal Rule for the previous America's Cup match, intended for 1914 but delayed until 1920.  Though an agreement to use the rule was not reached for that match, the 1914 US boats, Vanitie and Resolute, still roughly followed J-Class parameters.

Building Program:

There were only 10 J-class yachts designed and built.  Additionally, several yachts of closely related dimensions, mostly 23-Meter International Rule boats, were converted after their construction to meet the rating rules of the J-Class. 

Only the purpose-built Cup yachts, though, could compete in the America's Cup.  The "converted" J-Class yachts, while acceptable for Class racing events, were not admissible for America's Cup competition.  Responding to issues that surfaced in earlier defenses, the America's Cup rules required that all boats had to be sailed to the event on their own bottom.  Some critics pointed out the possibility that the challenger might, as a result, be disadvantaged by  being of heavier construction than the defender.  In order to avoid a situation that could be perceived as an undue advantage, the NYYC eventually agreed that all America's Cup J-Class yachts would be built to Lloyds A1 standards, ensuring that defender and challenger met the same minimum construction specifications (the nautical term is "scantlings").  Most existing yachts were not built to such standards, so the Cup-eligible boats thus ended up heavier than the ineligible J's.

(The issue of challengers having to build heavier boats due to the ocean crossing was a popular, if uncertain, explanation in the British press for the long string of American victories.  In practice, a number of challengers added internal bracing for the crossing, which was then removed before racing.  And on a few occasions defenders subsequently made the crossing in reverse in search of competition following their successful defense.  The rule requiring that the challenger sail to the event on her own bottom was actually instituted in response to a super-lightweight challenger towed to the match through canals and rivers from Canada.

The J-Class Yachts

Disposition:

Conceived at the height of the affluent 1920's, the J-boats arrived during the Great Depression.  They required enormous crews, and, despite expert attention to their technical details, still broke an astonishing number of masts.  While they were in most regards the most advanced sailing yachts yet built, and they were  indeed powerful sailing thoroughbreds formed in sleek lines that can race the pulse of almost every viewer, the glorious J's proved too extravagant for their own good.  Most had very limited sailing careers outside of America's Cup.  Ranger , whose 1937 cost was upwards of $500,000, was laid-up at the end of her debut season and never sailed again.  All of the American J's were scrapped between 1935 and 1941. Most of the British J's were either abandoned or scrapped.

When NYYC sought to revive the America's Cup in the 1950s, there was a faction that favored returning to the J-Class.  Mike Vanderbilt even stated that not only would he like to see the Cup contested in the large boats, but that if so he would consider rebuilding a new Range r to the design of the original.  Still, another faction hoped for smaller dual-use yachts that could be used in offshore racing when the Cup year was ended.  With cost estimates for a 1958-era J starting around three million dollars, the impulse for a J-Class defense faded away in the face of economic pressures and a compromise was reached to sail the America's Cup in International Rule 12-Meters.

The J-Class Resurgent

J-Class rigs today are no longer built of wood or dur-alumin, but with modern lightweight composites.  Their sail technology is long past being canvas duck, and many other subtle changes have been made to make the ongoing maintenance and operation of these yachts a realistic proposition.  Still, the J-Class owners have gone to great lengths to insure the integrity of the boats.  The J-Class is self-administered, rather than governed by an outside organization as is the case with almost all other classes.  This allows the members to more easily adapt the rules in order to serve the needs of these uniquely historic yachts.

Most of the surviving J's are available for charter.  Cambria was reportedly for sale in 2000.  Endeavour changed hands in 2006 for a reported $13.1 million USD, though as her former owner Dennis Kozlowski said, "No one truly owns Endeavour .  She's a part of yachting history.''

Recreations, Replicas, and a Tender:

For decades, most yachting fans thought that we would never again see the likes of these boats again, the few survivors would sooner or later fade away, and the whole history would be reserved for books and fading photographs, but following the restoration of the surviving hulls rumors grew throughout the late 1990's and early 2000's about building "new" J's.  In 2001, all of this dock talk began to become reality:

Ranger Wooden Boat magazine, March/April 2001, described a "Dutchman" who had commissioned a new Ranger built to the original's plan.  This incredible rumor came true, and a piece of lost sailing history was brought back to life.  The new version of this "Superboat", as Mike Vanderbilt once called her, was officially launched in October, 2003. 

Designed by Studio Scanu and Reichel-Pugh, and built by Danish Yachts, Skagen, Denmark, she is not an exact replica of the original. Some would term her a re-interpretation, as a number of changes were made including greater freeboard, and Ranger 's original designers did not participate in the project.  The new Ranger first competed head-to-head against other J's in Antigua, Spring, 2004.  It took some additional adjustment after launch by her owners and designers to seek the proper trim that would make her float on her lines, an essential step in the process of being officially rated a J-Class yacht.  Visit the Ranger Website for more info.  J-Class Management is also at work on a restoration of Bystander, tender to the original Ranger .

Endeavour II An Endeavour II replica is being built at Royal Huisman Shipyard, with a planned 2008 launch date.  Gerard Dykstra and Partners is leading the project, which features a lightweight Alustar (aluminum alloy) hull and carbon-fiber mast.  See additional photo at Yachtspotter

Lionheart Based on an unbuilt alternate design by Starling Burgess and Olin Stephens II that was considered for 1937's America's Cup defender Ranger , this new boat is being built at yards in the Netherlands for an expected 2008 launch.  Lionheart will be the longest J-Class yacht when completed. See more including photos of the completed hull at the Lionheart Website and the story of sailing onboard including photos and videos Cruising J-Class Style Aboard Lionheart at Yachting World Designer:  Hoek Design Builders: Bloemsma Aluminiumbouw and Claasen Jachtbouw BV

Svea Tore Holm's unbuilt 1937 design, said by some to be faster in the test tank than any of the original boats, is being pursued by Hoek Design

Name To Be Announced In late March 2008, reports of another replica about to begin construction appeared on the Classic Boat website .  Whether this is one of the known projects, such as Svea , above, or yet another replica about to become reality, such as Rainbow , below, should become known shortly.

Rainbow In late May, 2008, Dykstra and Partners announced that a new build of the 1934 America's Cup Defender Rainbow was underway, with an expected launch date of 2010.  Read the Press Release

Other projects: Hoek Design is also studying replicas of 1930's Enterprise and another boat from Yankee designer Frank Paine.  Yankee herself has also been rumored as a new project, as well.  Earlier reports of a Ranger alternate-design carrying the name of Seawolf may have been referring to the project that has become Lionheart , see above.  Whirlwind and Weetamoe are the only two designs of the original ten J's that aren't known to be sailing, building, or under serious consideration as of 2008.  The J-Class website points out that there are 10 unbuilt J designs from the 1930's, so the possibilities for more J-Class yachts are intriguing.

Yachting World reported in May, 2003 , that construction was underway on a yacht replicating the famous G.L Watson design Britannia .  Photos showed a nearly completed hull at Solombala Shipyard, in Arkhangel, Russia, and included interviews with the yacht's owner Sigurd Coates of Norway.  The design was adapted by Cesil Stephansen from published plans.  The original designer's modern descendent company, G.L.Watson & Co., Ltd., has no involvement with the Arkhangel boat.  Little was been heard of this ambitious project for years, until the yacht was finally launched only to become subject of a financial dispute, trapping her in Russia until 2009, when she "escaped" to Norway. 

In the Spirit

A similar project to return elegant yachts to competitive racing, the W-class, was set in motion by Donald Tofias, an American enthusiast.  He commissioned naval architect Joel White to design a new class with lines evocative of famous racing yachts like the New York 50's and the J-Class.  The first two boats, Wild Horses and White Wings , were built in Maine of modern cold-molded wood construction and launched in 1998.  It is Tofias' aim that there will eventually be a whole fleet of the beautiful W-class to regularly compete against each other.  The one-design W-76 is actually similar to the New York 50's.  Tofias' long-range plans involve a range of classes including 46, 62, 76, 105, and 130.  The 130's would be nearly identical in basic dimensions to the J-class. See the W-Class Websit e .

Further Notes:

K-Class: The Royal London Yacht Club made and withdrew its inquiry for a K-Class challenge in 1935.  The intent had been to reduce costs, not the least of which was hoped to be a lower velocity of mast replacement, but the K-Class line of thought was rejected for several reasons.  For one, the K-Class wasn't so much smaller than the J-Class as to have clearly led to significant savings.  Additionally, no K-Class yachts existed on either side of the Atlantic while several J's of various pedigree were available for testing, training, and racing in 1935.  Also a factor was that the NYYC was already actively considering another challenge at the time the RLYC began their communication  about the K-Class and it was the NYYC's policy to consider only one challenge at a time, in keeping with the Deed of Gift.

Sailing to the Event on Own Bottom: This provision of the Deed of Gift was at times strictly interpreted to the the degree of making sure that the challenging yacht actually was under her own sail while traveling to the match, not towed by another boat.  Challengers returning across the Atlantic after Cup matches concluded were sometimes towed for convenience. Eventually the NYYC agreed at various times to permit towing the yachts to the match, particularly when conditions were light, and in 1956, for the coming of the 12-meter yachts in 1958, the Deed of Gift was amended to eliminate the requirement.
