Sailing: Ainslie stays out in front

On course for three gold medals, the British squad here were yesterday gearing up for a final push over the last two days of the World Championships.

Ben Ainslie had another convincing win, only to slip to 11th in his second race. Nevertheless, he goes into his final race today in the Finn class at least assured of a medal.

Ainslie is enjoying a five-point lead over Rafael Trujillo as his fellow Briton Andrew Simpson slipped from second to third overall.

A second and a 10th for Leigh McMillan and Mark Bulkeley in the Tornado catamaran was also enough to keep them on top with three races to go.

But the most powerful performers have been Chris Draper and Simon Hiscocks in the 49er.

Their worst result in 11 races so far is a sixth, which they can discard, and they have two wins and six second places helping them to establish a 24-point lead over their nearest rivals.
