Beijing-bound sailors Sarah Ayton, Sarah Webb and Pippa Wilson retained their Yngling World Championship title in emphatic style, clinching victory in Miami with a day to spare.

The British trio dominated the 28-boat fleet from the first day of the regatta and secured gold after gaining an unassailable lead on the penultimate day of racing in Biscayne Bay.

Ayton, Webb and Wilson, who secured selection for Beijing by winning the 2007 World Championships in Cascais and the Olympic test event in Qingdao, have added to Ben Ainslie's gold at the Finn Gold Cup, and Nic Asher and Elliot Willis' win at the 470 Worlds in Melbourne last month.

Wilson described the trio's victory as "amazing" and admitted that they were fully fired up to defend their world title after missing out on the medals at the Rolex Miami Olympic Classes Regatta at the same venue two weeks ago.

"Going into the OCR we hadn't really raced since China, as we'd been working on a lot of equipment stuff,"

the 22-year Lymington sailor explained. "We didn't finish quite where we wanted to be at that event, which meant we were even more ready for the Worlds."

As defending champions 'Team Mirabaud' were not prepared to let the title slip from their grasp.

"In the past we've been in the same position, but have made a few mistakes. This time, I think our experience helped pull us through.

"We just sailed really consistently throughout the week - we had some pretty tricky conditions and some big breezes and so our teamwork has really shone through."

Ayton, Webb and Wilson count all scores within the top five heading into the final day of racing, but are safe in the knowledge that, even with the double-points scoring medal race still to run, the gold is theirs.

It is a huge confidence boost ahead of the Olympic regatta, but Wilson insists the girls are not about to get complacent in their Games preparation.

"It's great to be in the position we're in, but we're always moving forward and this is just a stepping stone on the way."

The other British crew at the Yngling Worlds, Shirley Robertson, Annie Lush and Lucy Macgregor, are in 10th place heading in to the final day of racing.
