|Specifications Under Current Rules|
The J/24 is an International One-Design keelboat class as defined by the International Sailing Federation. The J/24 is a one design class created to fulfill the diverse needs of recreational sailors such as cruising, one design racing, day sailing and handicap racing.
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 mould 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.
As of January 2009 approximately 5,475 J/24s have been produced. Approximately 20 new boats were produced in 2008, the average price of complete new boat without sails was approximately GBP20,000.
The International J/24 class has more than 50,000 people sailing 5,300 boats worldwide; is established in nearly 40 countries with well over 150 active fleets; and is still considered the "gold standard" for modern one-design keelboats around the world.
Authority, rules and regulations
The international authority for the class is the ISAF, 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.
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. IJCA is a "not-for-profit" organization.
J/24s are usually raced with a crew of five, but class rules require only that there be at least three crew, with a total combined weight under 882 lbs (400 kg).
Reasons for the J/24's popularity
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. This is one of the many advantages of One-Design sailing.
It is fairly easy and inexpensive to get hold of a used boat due to the number of boats produced. There are 136 active fleets in the US alone, which offer a lot of race competition. This makes the J/24 a popular boat for beginners and experienced sailors.
Manufacturers / Builders
The boat is not manufactured by the designer. The manufacturing is done by multiple companies around the world in France, USA, Italy and Argentina. J/24s shall be built only by builders licensed to do so under the copyright of J Boats, Inc., and shall comply with the building specifications detailed by the copyright holder.
