Iain Percy and Andrew Simpson finished Britain's dazzling Olympic regatta with a record fourth gold medal in Qingdao today after a thrilling climax to the Star class. Winchester's Percy, the Finn champion in Sydney in 2000, and Simpson, a 31-year-old Chertsey-born sailor, were left in ecstasy after sailing to Team GB's 17th gold medal in all at the Games following an astonishing finish to their keelboat medal race, a contest which was breathlessly described by another of the British champions, Ben Ainslie, as the closest that he had ever seen.
