It is the oldest international sporting trophy – dating back to 1851 – and stands as one of the hardest sporting endeavours. The New York Yacht Club, one of the most prestigious clubs in the world, held the trophy for 132 years before losing it in 1983 to Australia. Since then, the Cup has only been won by teams from the United States, Switzerland, and New Zealand. The current Defender of the America's Cup is Emirates Team New Zealand, representing the Royal New Zealand Yacht Squadron.
