Ben Ainslie says he's been inspired by Great Britain's gold medal winning exploits as he bids to become the most successful sailor in Olympic history.
Great Britain won six gold medals on Saturday - including three in the heptathlon, the long jump and 10,000 metres.
Ainslie said he'd watched the drama unfold on television and drew inspiration ahead of his attempt to add to Team GBR's golden tally.
"I took a bit of inspiration from Bradley Wiggins and the girls in the rowing a few days ago," the triple gold medallist told AAP.
"Certainly I've never seen anything like that in British athletics, so awesome."
Speaking about two hours before the Finn class showpiece final in Weymouth Bay, Ainslie refused to speculate about what it would mean to win another gold for Team GBR.
By winning his own fourth gold medal, Ainslie would equal Paul Elvstrom's tally.
But the Briton also holds a silver medal from the Atlanta Olympics, so he would supplant the Danish sailor as the most decorated sailing Olympian.
Standing in Ainslie's way is another Dane - Jonas Hogh-Christensen, who takes a slim two-point lead into Sunday's race.
It's pretty much a straight duel between Ainslie and Hogh-Christensen: Whoever finishes in front during the race takes the gold medal.
Dutchman Pieter-Jan Postma has a very slim chance of gate-crashing the party and taking gold, but only in the unlikely event of him winning the race and Ainslie and Hogh-Christensen finishing the race right at the back of the 10-boat fleet.
Meanwhile, Great Britain's Iain Percy and Andrew Simpson take an eight-point lead into the final Star class race.
They are in the box seat for the gold medal, but will need to watch out for Brazil's double gold medallist Robert Scheidt and Bruno Prada, who are second overall.
There is no Australian interest in either race.
Brendan Casey failed to qualify for the Finn medal race and Australia didn't enter the Star competition.
