Ben Ainslie is Britain's sailing superstar and is going for a third straight gold medal in China.
The 31-year-old is acknowledged as one of the world's great sailors and will add another layer to the legend should he triumph again.
Ainslie won his first Olympic medal - a silver - in the single-handed Laser class in Atlanta in 1998, aged 19, and added gold in Sydney in 2000. He then switched to the heavier Finn dinghy and clinched the Olympic crown in Athens four years ago.
He then spent time away from the Finn to compete in the America's Cup with Team New Zealand but returned in time to win the Olympic test event in Qingdao last year before securing his spot in the GB team ahead of Ed Wright.
To underline his credentials, Ainslie has since won a fifth Finn world title and a fourth European crown.
"Ben has managed to get himself into this position where recently he's unbeaten and that means when he lines up on the start everyone else in his race is expecting him to win," said Britain's Olympic sailing manger Stephen Park.
The Finn class gets under way on 9 August with the medal race on 16 August.
