An Artemis Challenge trimiran has set a new round-the-Island world record at Cowes Week, but organisers say it still needs to be confirmed.
Team GB Olympic stars were competing in the race, which raises money for good causes.
London 2012 windsurfing silver medallist Nick Dempsey, and match racing team Annie Lush, and sisters Kate and Lucy Macgregor were competing in the race.
Two time Olympic silver medallist Ian Walker also took park.
The race was started at 10am this morning (Thursday) by Zara Phillips, who herself took a silver in the team eventing at the London Games.
Skipper Michel Desjoyeaux and Ian Walker were first to complete the fifty mile sprint around the Island onboard MOD70 trimiran 'Foncia', in an unratified round-the-Island world record time of 2 hours, 21 minutes and 25 seconds.
Monohull 'Gamesa' won the IMOCA 60 class. Its crew including Mike Golding, Annie Lush and Kate Macgregor arrived in Cowes after 4 hours, 46 minutes and 56 seconds on the water.
The £12,000 prize money will be split between the winners of the two crews, and will go to Institute Curie and Save the Children.
