Sarah Ayton (left) and Sarah Webb celebrate their gold in Qingdao

Weymouth's Sarah Ayton and her crew of Sarah Webb and Pippa Wilson won the Yngling Class to add to last month's World Championship win.

And Paul Goodison then took gold in the single-handed Laser class.

Ayton's win could spell the end of double gold medallist Shirley Robertson's Olympic dreams.

"We are very pleased and very excited - we've had a great year, and are on a roll," said Ayton.

"One win leads to another, and we hope to carry this momentum into the Olympics next year. We haven't been off the podium once yet this year so we have to be confident that we will be the ones representing Great Britain here in 12 months' time."

The 37-year-old Robertson - who won gold with Ayton and Webb in Athens - was hoping to qualify for the Games with a new crew.

Robertson took time off after Athens to pursue other projects and gave birth to twins last summer.

But she hit the Olympic trail again in November with a new team of Annie Lush and Lucy Macgregor, and the trio finished third in the World Championships in Portugal last month.

The Isle of Wight-based Robertson's immediate Olympic future now sits in the hands of the selectors who must choose one British team in each class to compete in Beijing.

Some picks will be made on 18 September, but Robertson is hoping the selectors will let her prove her mettle at the Yngling World Championships in Miami in January.

Britain won three gold medals in Qingdao on Wednesday with Ben Ainslie (Finn), Bryony Shaw (windsurfer) and Stevie Morrison and Ben Rhodes (49er) taking the honours.

Nick Rogers and Joe Glanfield also won silver in the men's 470 dinghy.

"I'm delighted and so proud of the team's results here in Qingdao, which have surpassed all our expectations," said Skandia Team GBR Olympic sailing manager Stephen Park.

"The sailors certainly didn't have it easy, with some really tricky conditions and competition to content with, and they had to dig deep and grind out some strong performances when it really mattered.

"Of course it would of course be amazing to be in a similar situation when we return in 12 months' time, but there's a long way to go between now and then, and certainly we've seen a number of countries upping their game for this event."
