The United States Surfing Association was formed in 1961 to improve the sport’s image as well as to govern surf competitions throughout the United States. USSA members, such as Corky Carroll, Mike Doyle, David Nuuhiwa and Joyce Hoffman, competed in world-class surf contests all across the globe. Issued jerseys displaying their call numbers, they were judged on a point system through various heats, with the top point-getter taking home the championship trophy. Following the 1967 season, the USSA split into four regional groups: the Western Surfing Association, the Eastern Surfing Association, the Hawaiian Surfing Association and the Gulf Coast Surfing Association. Winners of the 1967 United States Surfing Championship held in Huntington Beach, CA were Corky Carroll (men's), Joyce Hoffman (woman's) and Dru Harrison (juniors).
