The best sailors in the world will be flying above the water at speed when the America’s Cup World Series begins in the summer of 2015.

Champion sailors Ben Ainslie, Dean Barker, Franck Cammas, Nathan Outteridge, Max Sirena and Jimmy Spithill will lead their respective teams into the first stage of the competition for the most storied trophy in international sport.

Commercial Commissioner Harvey Schiller says that he also expects at least one additional team will be joining as a late entry.

The America’s Cup World Series runs for two seasons in 2015 and 2016, ahead of the America’s Cup Qualifiers, Playoffs and Finals in 2017.
