The 1987 America's Cup, staged in Fremantle by Royal Perth Yacht Club
That could almost be a trick question. The first race, put on by the Brits in 1851, wasn't called the America's Cup. However, it was won by a boat called America, and subsequent races for that trophy became known as the America's Cup race. The winner of the next race, the first race known as the America's Cup race, was a boat named Magic. So, the answer to your question could be either America or Magic depending on which you consider to be the first America's Cup race.
The America's Cup originated in 1851 during a race around the Isle of Wight in England. The event featured the yacht "America," representing the New York Yacht Club, which won the race against a fleet of British yachts. This victory led to the establishment of the America's Cup as a prestigious international sailing competition, making it the oldest trophy in international sport. The event has since evolved into a major yachting championship, held every few years.
Transpacific Yacht Race was created in 1906.
In 1851, in response to an invitation from a few British yachtsmen, several members of the New York Yacht Club formed a syndicate to build a boat to travel to merry old England and race the fastest vessels the Royal Yacht Squadron could put forth. Designed by a gentleman named George Steers, the boat that was built was called "America", and after winning a race in England against 17 British vessels, the trophy was brought home to the US and named after the yacht that won it, not the country. Common mistake.
