He won the 2009 RS:X World Windsurfing Championships there.
He won the 2011 Skandia Sail For Gold Regatta there.
They are his home waters. Dempsey trains at the Weymouth
and Portland National Sailing Academy - the 2012 Olympic sailing venue and has done so since 2001.
So Weymouth-based windsurfer Nick Dempsey has every right to feel strong going into the Olympic Sailing Test Event which starts on July 31st and run through to August 13th.
He is excited about the upcoming competition but he also knows that a lot of his rivals have been training on the waters of Weymouth Bay so his home advantage may be slipping away.
He said: "I know the waters well but, as more competitors spend time here, they become familiar with it too so I'm making the most of it."
London 2012 will be Nick's fourth Olympics and, with a year to go, he said he is feeling "confident". He also has a secret weapon at home. His wife Sarah. She has two Olympic Gold Medals to her name so is helping to keep Nick focused on the job in hand and not what might be if...
Here's a recap of Nick's Olympic windsurfing bio.
- Competed in Sydney 2000 at the age of 19 - finsihed 16th
- Won the bronze medal in Athens 2004
- Finished 4th in Beijing 2008
- 2009 RS:X World Windsurfing Champion
This last result means Nick has 'unfinished business' and it is this that is also driving him onwards with a single minded sense of purpose. "There's no other competition like the Olympics" He says "You can win everything else but nothing compares to it and it being a home Games makes it more special."
So who are his main medal rivals?
Well, there's the 'Flying Dutchman', Dorian van Rijselberge who has been there or there abouts for the last few years. As yet he has failed to land the big punch but he not to be underestimated. He has incredible speed. He is young and he is hungry
Then, you can never discount the Kiwis. Jon-Paul Tobin will be racing at the Test Event but back home watching from afar will be Tom Ashley, the 2008 Olympic Gold Medallist. He is on is way back from injury and illness but JP is sailing faster than ever and is fed up with being the bridesmaid. He's never competed in an Olympic Games having been beaten in the New Zealand Q system by first Aaron Macintosh and then Tom. There is no lack of motivation downunder
There's a battle royal going on in Poland right now as well. Piotr Myszka, the 2010 RS:X World Windsurfing Champ is slugging it out with the longstanding number 1, Przemeslaw Miarczynski. It's Pont who will be at the Test Event not Piotr but word on the street has it that these two top racers may have lost their edge when the wind picks up.
The bookmakers will not discount Julien Bontemps (FRA), 2008 Silver medallist or any racer that has ISR on his sail so Nick Dempsey will certainly have to work hard and work smart to secure his lifetime ambition which is to win Gold on the waters he can see from his kitchen window.
"Training is going well and I'm on target. It's all getting pretty exciting." He said "Competing in the Olympics doesn't get easier but the goal [of a gold medal] becomes closer"
His current training schedule can mean up to three hours out on the water each morning, followed by afternoons spent on a rowing machine or in the gym, or analysing his performance with the help of a coach and physiologist. As the Olympics get closer the training gets more intense.
"Everything is becoming more calculated and every training session is more precious. You have to make the most of every day. It's not chasing the dream anymore. You are chasing something you know you can do."
