Ainslie won nine of his 11 races in the Finn class

Ainslie dominated the Finn class and ended with nine wins in 11 races.

GB's other wins came from Paul Goodison in the Laser, Chris Draper and Simon Hiscocks in the 49er class and 470 sailors Nick Rogers and Joe Glanfield.

Britain also claimed silver in the Yngling and Star and bronze in the Laser Radial and 470.

Ainslie was making his comeback after a year away from the Olympic class sailing due to America's Cup commitments.

He was delighted with his performance in the regatta, which was a warm-up for the Beijing Olympics in 2008.

Pleasantly surprised is probably the best way to put it - I'm pleased with the result Finn winner Ben Ainslie

"I'm very happy with the result, and above all else it's good experience to be out here in China and see what the venue and the 2008 waters are like.

"I was pretty open-minded coming to this event as I'd only done five days' training in a whole year, so I wasn't really sure where I'd stand.

"Pleasantly surprised is probably the best way to put it - I'm pleased with the result."

Britain's first gold of the day went to 49er World Champions and Athens bronze medallists Chris Draper and Simon Hiscocks.

"When we crossed the finish line we both said 'It's been a long event!' This event's more days than we've had races!" Draper explained.

"A lot of people were worrying that it would be a Mickey Mouse venue and it wouldn't necessarily be the people at the front of the fleet that you'd expect to be," said Draper.

"I think we're pretty happy that it's not the case.

"The racing, for us at least, has been genuinely decent and the race officers were well on top of it so it was a fair regatta."
