Former America's Cup winner John Bertrand says the next Cup will showcase the biggest changes in the race's 160-year history.
The next event will be in San Francisco in 2013 with multi-hull vessels.
Bertrand was the first foreigner to win the America's Cup, in 1983.
He says combining the new boats and the course in San Francisco Bay is a high-risk strategy, but it should lead to exciting racing.
He says the Cup has always been about high technology and the changes will attract new fans beyond the sailing community.
The event, the 34th America's Cup, will be hosted by the Golden Gate Yacht Club.
Oracle Corp chief executive Larry Ellison, whose BMW Oracle team won the event at Valencia, Spain, in February 2010, sails for the club.
Racing will be in San Francisco Bay and visible to spectators from the Golden Gate Bridge and other landmarks.
The America's Cup was first contested in 1851. It was raced from Newport, Rhode Island, from 1930 to 1983.
