Skipper Shirley Robertson became the first woman in Olympic history to collect gold in two different classes of boat as she won with crew Sarah Ayton and Sarah Webb.
There was British more British success elsewhere as badminton pair Nathan Robertson and Gail Emms won silver in a thrilling mixed doubles final.
And there is a promise of more to come, as other members of the Team GB sailing squad are guaranteed medals as the regatta comes to climax tomorrow.
They will be hoping to follow in the golden footsteps of Robertson as she repeated her Sydney success.
"What about a triple?" the 36-year-old from Dundee said as she toasted her latest triumph.
"It's been hard all week and we have taken each race as it goes along and not made errors.
"I'm overwhelmed that we've put it all together and made it happen."
Ayton, from Weymouth, a venue for London 2012, added: "The legs are like jelly and all over the place. It's been hard work but worth it.
"The conditions haven't been the strongest for us and we've really had to raise our game. It's unbelievable."
Meanwhile, Robertson and Emms were celebrating their silver medal and setting their sights on gold in Beijing in 2008.
Robertson said: "There's no reason why we can't improve - we're young enough.
"We'll be 31. That's not too old at all and there's no reason why we can't be better if everything goes smoothly."
