The America’s Cup is a trophy awarded to the winner of the America’s Cup match races between two sailing yachts. One yacht, known as the defender, represents the yacht club that currently holds the America’s Cup, and the second yacht, known as the challenger, represents the yacht club that is challenging for the cup. The America’s Cup is the oldest active trophy in international sport.

The trophy was originally awarded in 1851 by the Royal Yacht Squadron for a race around the Isle of Wight in England, which was won by the schooner America. The trophy was renamed the America’s Cup after the yacht and was donated to the New York Yacht Club (NYYC) under the terms of the Deed of Gift, which made the cup available for perpetual international competition.

The history and prestige associated with the America’s Cup attracts not only the world’s top sailors and yacht designers, but also the involvement of wealthy entrepreneurs and sponsors. It is a test not only of sailing skill and boat and sail design, but also of fund-raising and management skills.

The trophy was held by the NYYC from 1857 until 1983 when the Cup was won by the Royal Perth Yacht Club, represented by the yacht Australia II, ending the longest winning streak in the history of sport.
