For the 2024 defense the Defender Emirates Team New Zealand chose the Catalan city of Barcelona, Spain. The races of the 37th America's Cup took place between September and October on the AC75 yachts which were confirmed as the official boats (with 8 sailors on board instead of the 11 from the previous Cup). For this edition, a second boat was introduced alongside the AC75: the AC40 foiling monohull, a 12-meter One Design vessel (identical for all teams) with a crew of 4. The AC40 was used for the two Preliminary Regattas in 2023 (Vilanova i la Geltrú, Spain, and Jeddah, Saudi Arabia), as well as for the UniCredit Youth America's Cup and the Puig Women's America's Cup, which took place in Barcelona in 2024.
