Organizers of the 34th America's Cup said the event has attracted 15 teams from 12 countries that would begin their quest for the Cup with 2011 America's Cup World Series stops in Cascais, Portugal; Plymouth, England; and San Diego.
As the entry period closed at midnight Thursday, 14 challengers had filed applications for the America's Cup, which will be held in San Francisco in September of 2013. Twelve have been validated and the other two will be checked against qualification requirements in the coming days.
With Oracle Racing previously accepted as the defense candidate, 15 teams could be confirmed.
"Fifteen teams promises an exciting America's Cup World Series, Louis Vuitton Cup Challenger Series and ultimately 34th America's Cup Final," said Iain Murray, regatta director and CEO of America's Cup Race Management, in a statement.
"The new wing-sailed, multihulled yachts will be fast and physically demanding, keeping the racing dynamic and interesting until the finish," he added. "We are looking forward to seeing these teams on the AC World Series circuit later this year. It is time to go racing."
America's Cup Event Authority said the inaugural AC World Series will begin in August in Europe. Formal announcements will be made with officials in each city.
