Scott, who claimed bronze at last year's event, won both races by a sizeable margin to take an early lead for Britain's in the men's heavyweight event.

Ben Ainslie is poised in third place with 5,2 from his opening races, and Andrew Mills is eighth.

"I'm really pleased with that – you can't do any better than a 1,1 so it was a great start," said 23-year-old Scott.

"I've set myself a target of trying to prove this year that I'm capable of winning Olympic gold and to do that I feel I have to try and win everything I do, so I suppose that's the aim for this week."

Britain's team has also taken an early lead in the 49er, 470 Men's and RS:X men's windsurfing events, and is equal first in the Laser, with Lucy Macgregor's women's match racing team coming through their three opening round-robin matches unbeaten with substitute crew Mary Rook.

Rook was called up to join the Macgregor sisters after Annie Lush was injured falling 10ft from the Elliot 6m boat earlier in the week.

"It was a pretty big shock, but Annie was taken to hospital and checked out pretty quickly," said Macgregor.

"Nothing is broken, so hopefully after a couple of weeks' rest and recuperation she'll be feeling well enough to start training again - but we're not going to rush it.

"We're lucky to have got Mary out here.

"It takes a bit of getting used to having someone new in the boat, having spent so much time in the Elliot with the three of us, so we have to think a little bit differently about things and work on our communication, but our boat handling is pretty strong."

Paul Brotherton and Mark Asquith, at their first event back after being sidelined through injury, top the standings in the 49er class thanks to 1,3,2 from their three races, while team-mates Dave Evans-Ed Powys and John Pink-Rick Peacock occupy second and third spots.



Britain's 470 men's teams also got their regatta off to a good start, with two-time world champions Nic Asher and Elliot Willis (pictured) in first overall, and Luke Patience and Stuart Bithell just behind in second.

A consistent day of two second places in the RS:X Men's windsurfing event helped Nick Dempsey take an early lead, while Paul Goodison is in equal first in the Laser class.

In the 470 women's event, Penny Clark and Katrina Hughes are poised in third overall, with Sarah Ayton and Saskia Clark sixth, while British sailors are in fourth after day one of the RS:X Women's and Laser Radial events through Bryony Shaw and Alison Young.

In the Paralympic classes, John Robertson, Hannah Stodel and Steve Thomas are second with 3,2 in the Sonar event, SKUD duo Alexandra Rickham and Niki Birrell are currently third overall, with Megan Pascoe eighth and Helena Lucas 11th in the 2.4mR event after day one.
