Helena Lucas – the only woman in the class – is sure to win at least a silver in the one-man keelboat fleet, as she currently sits in gold-medal position with a nine-point advantage over Germany’s Heiko Kroger with one race to come.
World champions Alexandra Rickham and Niki Birrell are guaranteed at least a bronze in the SKUD class. They are third overall, two points behind Jen French and J-P Creignou, of USA, but too far ahead of the Canadian boat in fourth to be caught.
However, Australian pair Dan Fitzgibbon and Liesl Tesch hold an unassailable lead in gold medal position.
And the Sonar crew of John Robertson, Hannah Stodel and Steve Thomas could still make it a medal hat-trick as they are in bronze-medal position, just one point behind Germany in second - although their placing is not secured.
"Having led for most of the week I’ve obviously got my eye firmly set on the gold medal but I’m not too excited yet as I still know there is a job to do," said Lucas.
"I’ve got a nice points’ cushion so I will go out there, enjoy the race and keep my eye on Heiko.
“I don’t think the boys in the fleet were too happy at the beginning of the week with a girl leading! But I think they have got used to the fact I’m up there and sailing really well. I think they are resigned to the fact they have got a bit of a job on their hands to beat me."
