America's Cup Management announced on July 5, 2007 that the protocol for the 33rd America's Cup had been agreed between the Defending yacht club, the Société Nautique de Genève (SNG) of Switzerland and its Challenger of Record, the Club Náutico Español de Vela of Spain. Golden Gate Yacht Club sued, successfully arguing that Club Náutico Español de Vela was not a valid challenger. The challenge was upheld, and Golden Gate Yacht Club's team, BMW Oracle Racing, sailed against SNG, represented by the Alinghi team, in February 2010 in Valencia, Spain. The competing boats, Alinghi 5 and USA 17 were both 90-foot multihulls. The rigid wing sail of USA 17 provided a decisive advantage and Golden Gate Yacht Club won the 2010 America's Cup by a considerable margin.
