The America's Cup is an international sailing competition that has been held since 1851. Participants in the race include racers, yachtsmen, catamarans, and yachters. Racers are individuals who compete in the race, while yachtsmen are experienced sailors who own and operate a yacht. Catamarans are two-hulled boats that are designed for speed, and yachters are people who sail for pleasure or sport. All of these participants come together to compete in the America's Cup, making it one of the most prestigious sailing competitions in the world.
