Nick Dempsey might be guaranteed a silver from the Weymouth and Portland International Regatta, but the Norwich windsurfer insists he only has one gold on his mind heading into today's finale.

The 30-year-old has been in devastating form on London 2012 waters in the test event for next year's Games, winning four of his ten races to head into the medal race in just 24 hours time in second.

Dempsey's lead ahead over Julien Bontemps from France in third guarantees him at least a silver but with Holland's Dorian van Rijsselberge 14 points ahead he knows he still has work to do.

But Weymouth's waters have been kind to Dempsey in the past. He won the Skandia Sail for Gold there in June and the RS:X World Championships in 2009 at the same venue. And he has vowed to do everything in his power to finish top of the pile again as he goes in search of reliving past glories with London 2012 looming.

'This regatta has gone so well and I am really pleased with how everything has gone heading into the medal races,' he said. 'I can't lose second thanks to my superior points difference over third which is amazing and if you go into the Olympic Games in that position then you can never ask for more.

'And I think I have some opportunities to get a few guys between myself and Dorian because I think I need two or three to finish ahead of him for the win.

'It will be quite difficult but not impossible and I came here looking for the gold and I will be doing all I can to make that happen. It is not over yet, it is far from over, and I will attack him on in the medal race and try to get that gold.'

Dempsey and van Rijsselberge have been the standout RS:X performers all regatta, going head-to-head in every race.

'I have loved the battle,' added Dempsey. 'But he changed the rules on my in that last race on Tuesday so I am not going to be quite as nice as I have been in the medal race. '
