Sir Ben Ainslie won four Olympic gold medals in sailing in 2012 and last month was the tactician on board Oracle Team USA when it won the America's Cup in San Francisco.
Britain has never won the competition since the event was first held in 1851 and some say the expense of running a team has made it a niche sport funded by billionaires.
Sir Ben told HARDtalk he was "working incredibly hard to get the money" for his British team, adding that he wanted to have a "credible chance of winning."
