The Second World War marked the end of the J-Class, and when America’s Cup racing began again in 1958, it signaled the beginning of the 12-Metre era. The Americans would successfully defend eight more times over the next 25-year period. Sadly, in 1939, all but three of the original ten J’s were used as scrap metal for the war effort. The three surviving J-Class yachts have been restored and still sail in regattas around the world.
