International yacht-racing trophy named after the US schooner America, owned by J L Stevens, who won a race around the Isle of Wight 1851. Offered for a challenge in 1870, it is now contested every three or four years, and is a seven-race series. The USA have dominated the race, only twice losing possession, in 1983 to Australia and in 1989 to New Zealand, then regaining it after a court battle. All races were held at Newport, Rhode Island, until 1987 when the Perth Yacht Club, Australia, hosted the series. Yachts are very expensive to produce and only syndicates can afford to provide a yacht capable of winning the trophy.
