Lack of wind prevented half of Saturday's scheduled 10 medal races taking place on the final day of the first major pre-Olympic test regatta at the 2012 Games sailing venue.

However, calm waters on a sun-drenched day in Weymouth and Portland Bay on the south coast of England did not stop the six-day programme being hailed a "huge success" by organisers.

There were participants from 38 countries in more than 500 boats competing in all 10 Olympic classes, including the new women's match racing event.

"We've done well with the racing - the race teams have done a really good job," said Royal Yachting Association competitions manager David Campbell-James.

"We're hoping for a lot of good feedback. The feedback I've had from the coaches has been good. They see we're working hard but we still have three years to go."

At a time when a row continues to simmer over where some Olympic events will be held, notably boxing and shooting, there are no such worries for Weymouth and Portland.

The area had the first 2012 facility to be completed over three years ahead of schedule after an upgrade of the existing National Sailing Academy.

"It has been a complex event, bigger than any previously staged of its kind in the UK, with Olympic and Paralympic classes racing as part of the World Cup," said Campbell-James referring to the test regatta.

Medal race day on Saturday attracted over 1,000 spectators into the marina but there was no racing in the Finn, Star, Laser, RS:X men's and women's windsurfing classes.

British Olympic Star champions Iain Percy and Andrew Simpson were left kicking their heels but secured gold without having to race, having not dropped from top spot all week.

Britain, Australia and Netherlands dominated the regatta with two golds apiece.
