What's happened so far?
Fletcher and Bithell went into the final medal race, where double points are awarded, in second, four points behind New Zealand's Peter Burling and Blair Tuke, but victory for the Britons saw them claim the title. It is a first Olympic medal for Fletcher, who finished sixth with Alain Sign in the same class in Rio, while Bithell also took silver in the 470 class alongside Luke Patience at London 2012.
Scott made it two golds for Britain in an hour in the Finn class. He had a nine-point lead going into the final medal race but had to play catch-up after a poor start and crossed the line in fourth, which was just enough to keep him ahead of Hungary's Zsombor Berecz. It is Britain's sixth successive title in the boat dating back to Iain Percy's success in Sydney 21 years ago.
