In 2000, Bertarelli founded the yachting syndicate Team Alinghi, which in 2003, representing the Société Nautique de Genève, won the Louis Vuitton Cup before beating Team New Zealand in Auckland to win the America's Cup. It was the first time a team had ever won the coveted sailing trophy on its first attempt, with the victory bringing the Cup to Europe for the first time. Team Alinghi hired sailors from many different nationalities, including Russell Coutts and Brad Butterworth, respectively skipper and tactician of Team New Zealand's 2000 crew. Bertarelli was Team Alinghi's only Swiss national serving as navigator in 2003 and subsequently as an afterguard runner and grinder in 2007, when Team Alinghi defended the America's Cup in Valencia. On July 3, 2007, Alinghi beat Team New Zealand in race 7 by 1 second to retain the America's Cup, winning the series 5–2.
