Ian Percy and Andrew Simpson finished first ahead of Brazilian rivals Robert Scheidt and Bruno Prada in race 5 and then second in race 6 in another photo-finish with Scheidt and Prada. This keeps the British pair in the overall lead, four points ahead of Scheidt and Prada, with four races and the medal race still to go. In third place, three points further back, are Fredrik Loof and Max Salminen of Sweden.

Percy: "We’re four points ahead and I call that even with the Brazilians and Swedes. With six races to go all we can say is we’re going to battle for every place in each."

In the women's Radial class event Alison Young sailed a blinder in her two races, finishing second in both behind the new flying Irish star, Annalise Murphy, who has won all four Radial races to date.

Both these women love the stronger breeze and they out-sailed regular class winners, Evi Van Acker of Belgium and Marit Bouwmeester of the Netherlands. Young is now fourth overall with a lot of racing to do, but it is good to see GBR finally doing well in this event.

Young: "It was a good day, two seconds so I‘m pretty pleased with that. It was a bit better than yesterday and a good place to build the rest of the regatta from. I started better today which made life a little bit easier."

And so to Ben Ainslie. Another tough day out in the Bay for the four time medalist. It seems that no matter what he does, Jonas Hoegh-Christensen of Denmark does it better. The Dane has beaten Ainslie in all six races sailed and has a ten point lead after the discard today. Dropping his seventh, Hoegh-Christensen has a near perfect 1, 1, 2, 1, 2 score. Ainslie, counting a 2, 2, 6, 4, 3, has four races and the medal race on Sunday to turn things around.

In the RS:X which got underway Tuesday it was an unspectacular start for both Nick Dempsey and Bryony Shaw. Dempsey finished fourth overall after two races with a 5 and 7. The top three, Dorian Van Rijsselberge of the Netherlands, Przemyslaw Miarczynski of Poland and Toni Wilhelm of Germany, finished in that order in both races.

Dempsey: “It was nice to get going. I felt pretty calm actually, far calmer than I have been at previous Games which is a good sign. When I was racing today I was just sailing like I would at a normal regatta which I think bodes well for the rest of the week. I think it will all come together.”

Bryony Shaw finished the opening day in sixth with a 7 and 6. Lee-El Korzits of Isreal won the first and Marina Alabau of Spain the second and they lead overall with third Olga Maslivets of the Ukraine.

Bryony: "It was a reasonably good day and it just shows how good my board speed was. I can take a lot of positives out of this solid start with no major mistakes."

Now for the bad or at least not so good news.

Stevie Morrison and Ben Rhodes raised hopes when they finished third in their first race of the day. But then in the second race Morrison and Rhodes capsized with the kite up, after Morrison missed a toe strap on the gybe, and never recovered. They finished 18th and remain in 12th place overall after four races, but theirs is a long series. Overall Outteridge and Jensen lead by nine points from Burling and Tuke, third are Allan Norregaard and Peter Lang of Denmark.

And finally the Laser event. Defending champion Paul Goodison finished the day down in 12th and has a score-line of 10, 23, 16, 2. Goodison has a back problem and the second place in the final race was achieved in a lighter wind strength. The Lasers do another two races Wednesday before their lay day and Goodison will be getting physio treatment to get him back out on the track.

Goodison: "I put my back out at the beginning of the second race yesterday so I’m in quite a lot of pain. But you only get one chance at this every four years and you’ve got to do whatever it takes."
