The 37th America's Cup begins in Barcelona, where Team New Zealand defends its title against Britain's INEOS Britannia, led by Ben Ainslie. This marks Ainslie's team reaching the finals for the first time in 60 years, having recently defeated Italy in the Louis Vuitton Cup. The America's Cup, the oldest international sporting trophy, dates back to 1851, with Britain yet to claim the trophy they helped establish. Ainslie acknowledges the formidable challenge posed by the New Zealand crew, likening them to the All Blacks in rugby. Both teams have adapted their strategies and boats, with New Zealand boasting a history of three consecutive wins, making them the favorites. The series will be a best-of-13, with the first to seven victories taking the trophy home.
