Although sailing as a means of transportation predates history, sport sailing—or yachting—seems to have originated in the 17th cent. in Holland. From there it was introduced into England (c.1660) by Charles II, and eventually spread to the American colonies. Then, as now, it was common for sport sailors to join together for social and recreational purposes in groups known as yacht clubs. The world's first such club was founded (1720) at Cork, Ireland. The oldest continuously existing club in the United States is the New York Yacht Club (NYYC; founded 1844). In 1851 members of the NYYC raced the schooner America against British competitors around England's Isle of Wight. Victorious, they deeded their trophy to the NYYC. It became known as the America's Cup, giving its name to the oldest and most prestigious event in international sailboat racing. The United States won every America's Cup (the event has been held irregularly) between 1851 and 1983, when it was won by Australia. Since the 1980s radical changes in boat design, lawsuits involving Cup teams, and even charges of espionage and sabotage have transformed and roiled Cup competition; in 2013 and 2017 foiling wing-sailed catamarans were used. The United States regained the Cup in 1987, then lost it to New Zealand in 1995. New Zealand lost to Switzerland in 2003, the United States held it from 2010, and New Zealand regained it in 2017.
