Welcome to the Official Website of The J Class Association!

J Class Yachts were born from the introduction of the 'Universal Rule' in 1930, which for the first time efficiently controlled the size and performance of yachts built to compete for the America's Cup. Ten massive yachts conforming to the J rule were built between 1930 and 1937, although more were designed and tank tested. They were all but extinct, however three English yachts survived.
