Ainslie's America's Cup Quest

The America's Cup, the world's oldest sporting trophy, was invented by Britain. Yet in its 166-year history, Britain has never actually won it. Now, the most successful sailor in Olympic history is attempting to make his obsession a reality - by bringing the Auld Mug back to the UK.

Natalie Pirks has been to Bermuda, where the competition is being held, to meet Sir Ben Ainslie, his team and the boat they are pinning all their hopes on.
