J-class yacht

J- class refers to a class of boat for large keel yachts according to international rules. With this particular sailing yachts racing for the America 's Cup between the years were held in 1930 and 1937.

History of formula

British yachts sailed to international rules, which required a boat longer than 48 feet, a Bermuda rig. The Americans wanted to participate with larger yachts. The international Formula rules on the yacht size was divided into letter classes. Scale was the waterline length here. The letter J stand for the length of 75-87 feet. The rule was based on ideas of yacht designer Nathanael Herreshoff / USA. The waterline length should be limited, the sail area freely selectable. The displacement of the yachts should rise and the draft will be limited at 15 feet.

J- formula

  • Length at Waterline (LWL): 26.51 m
  • Length Overall ( LOA): 41.54 m
  • Width: 6.36 m
  • Draft: 4.57 m
  • Sail area: 701 m²
  • Displacement: 160 tons maximum

J- Class yachts

A number of already existing British yachts were the new J- formula adapted to sail with the new buildings regattas can:

Only ten pure J Class yachts were ever built, including four in the UK and six in the United States:

Moreover, it was started in Sweden in 1937 with the construction of the J -S1 Svea, designed by Tore Holm. The building was never completed during the Second World War.

J Class Today

Today there are still three original J-Class yachts obtained in trip, these are:

  • Shamrock V; Restored 2000-2001
  • Endeavour; Restored in 1988, 2001 and 2010-2011
  • Velsheda; Restored in 1997 and 2001

The J Class Association has set itself the objective of maintaining the class and allow races for historic and newly built J- Class yachts. Participants are solely yachts that were built according to original designs from the 1930s. In addition, a handicap system has been defined, which governs the time allowance between different fast boats.

So far, three J-Class yachts have been reconstructed: the first was named after its original model on the name Ranger and came in 2004 back on track. The Endeavour II was rebuilt on the Royal Huisman Shipyard under the name of Hanuman and was completed in April 2009. In addition, the Lionheart was built by one of the discarded original plans of the Ranger called 77F a yacht by Hoek Design in the Netherlands. The Lionheart was completed in June 2010 and received the sail number J- H1.

According to other historical blueprints of Frank C. Paine, the Atlantis is built. You will get the sail number J 7. The construction of the Svea is planned from 2010. In addition, the construction of a replica of the Enterprise in a further project is planned. Your launch will take place in 2011. The Yankee is also reproduced under the sail number J H3 in the Netherlands.
