Video: Oracle team member's lucky escape

Oracle Team USA's first week on the water in their new AC50 hasn't been without incident, with the America's Cup defenders losing a man overboard.

Grinder Graeme Spence was thrown off the front of the platform as the winged catamaran decelerated in a tack, falling under the boat between the hulls and narrowly avoiding the foils and rudders.

"You're very aware of everything that's around you - the four foils in the water with you," Spence said.

"I just sort of froze a little bit and then was quite relieved to realize I was out the back of it."

Oracle skipper Jimmy Spithill said it was a long few seconds waiting to get a thumbs up from the sailor in the water.

"Any time you see or hear someone go over the front it's a real bad feeling," said Spithill. 

"That time from when he goes over the front to when you see him pop back up on the surface and see the thumbs up, always takes too long."
