Sir Ben Ainslie hopes to bring America's Cup home to UK

The America's Cup is the biggest prize in world sailing, but has never been won by a British team in its 165 year history.

Four time Olympic gold medallist, Sir Ben Ainslie, is hoping to change that with a catamaran which has more in common with a Formula 1 car or an aeroplane than a yacht.

He helped the Americans win last time round, and now says his crew is ready to bring the cup back to where it all began.
