J/24
The J/24 is an international One-Design keelboat class built by J/Boats and defined by World Sailing.[1] The J/24 was created to fulfill the diverse needs of recreational sailors such as cruising, one design racing, day sailing, and handicap racing.[2]

The J/24 class has more than 50,000 people sailing 5,500 boats worldwide; is established in 27 countries with well and is the world's most popular one design keelboat.[3][4][5][6][7][8]
History
In the summer of 1975 Rodney Johnstone designed and built hull number 1 in his garage in Stonington, Connecticut. "Ragtime" would serve as the master mold for the subsequent hulls. This design allowed him to start the very successful J-Boat company with his brother Bob Johnstone. By 1978 the class was popular enough to hold a one-design regatta in Key West with twenty boats on the line.[9]
Early boats (hull numbers up to 3000) need a lot of work to rebuild their keel shape (move material forward) to make them point and sail fast in light wind. These older boats can be modified if one wants a competitive J/24. New boat manufacturing has been done by multiple companies around the world in UK, France (only 5), Croatia, USA, Italy and Argentina.[10] In the US, J/24s are built by US Watercraft. Italy could still build new boats.
As of January 2009, approximately 5,475[11] J/24s have been produced. Approximately 20 new boats were produced in 2008. The average price of a complete, new boat without sails was approximately £20,000. (31,370 USD)[11]
Authority, rules and regulations
The international authority for the class is World Sailing, which shall cooperate with the International J/24 Class Association on all matters regarding these rules. Interpretations of these rules shall be made by the ISAF, which in coming to its decision may consult the International J/24 Class Association and the copyright holder.[2]
The International J24 Class Association (IJCA) has the sole authority worldwide for the conduct and management of the International J/24 Class. The IJCA Constitution, the By-laws and other regulations are binding on all members, and all registered J/24s shall conform to Class Rules and any limitations imposed by the IJCA and ISAF.[12] IJCA is a "not-for-profit" organization.
Current rules (as well as the history of changes) for the International J/24 Class is available from World Sailing web site[13]
Crew requirements
J/24s are usually raced with a crew of five, but class rules require three crew, with a total combined weight of under 882 lbs (400 kg).
Reasons for the J/24's popularity
The J/24 is no longer considered the most modern sailboat in its class, but it is still a very popular sailboat among keelboat racers. While some of the world's best J/24 sailors have the latest version J/24, a well-prepared 1977 model, built to the same shape and weight with rigid end-grained balsa core construction can still win sailing the class world championship even after 30,000+ miles of trailering.[3] This is one of the many advantages of One-Design sailing that the J/24 is benefitting from.
Another reason for its popularity is that it is fairly easy and inexpensive to acquire a used boat and gear due to the large number of boats produced. There are 136 active fleets in the US alone,[14] which offer a lot of race competition. This makes the J/24 a popular boat for beginners and experienced sailors.
