It was plain sailing for Great Britain as two gold medals were claimed in the space of an hour on Tuesday morning.
Dylan Fletcher and Stuart Bithell claimed the tightest of victories in the 49er while Giles Scott successfully defended his Finn crown.
The 34-year-old’s victory means Britain have claimed six successive titles in the Finn dating back to Iain Percy’s success in Sydney 21 years ago. Sir Ben Ainslie then won three consecutive titles before Scott clinched his first gold in Rio.
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 enough to keep him ahead of Hungary’s Zsombor Berecz in silver.
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 the narrowest of victories for them and third for New Zealand saw the British pair claim the title.
Fletcher and Bithell’s biggest obstacle turned out to be Germany but, having taken the final turn in second, the British pair just edged over the finish line in front.
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.
Bithell missed out to Fletcher and Sign for Rio, and the pair were rivals before deciding to team up in a bid to qualify for Tokyo. The decision brought immediate dividends as they won European and world titles, and now the biggest prize of all.
There was also a silver medal for John Gimson and Anna Burnet in the mixed Nacra class, with Hannah Mills and Eilidh McIntyre poised for gold in the women’s 470 on Wednesday.
Fletcher’s fiancee, Charlotte Dobson, and her crewmate Saskia Tidey missed out on a podium place in the women’s 49er FX earlier, coming seventh in the medal race and sixth overall.
Jack Laugher bagged the third Olympic medal of his diving career with bronze in the men’s 3m springboard final at the Tokyo Aquatics Centre.
The 26-year-old from Harrogate won gold and silver at Rio 2016 and he completed the set here, claiming a place on the podium as Xie Siyi took top spot, with Chinese compatriot Wang Zongyuan finishing runner-up.
It was a consistent display from Laugher, who did not drop below 81 points in his six dives with a best of 96.9 from his forward four and a half somersaults tuck.
Fellow Briton James Heatly qualified in fourth place but was unable to recover from a disappointing first dive in the 12-strong final and finished ninth.
A strong morning for Team GB but there was also some disappointment as Adam Gemili pulled up injured during the 200m heats.
The emotional sprinter revealed he went into the event carrying a hamstring injury.
Meanwhile, Caroline Dubois’ hopes of securing a medal in the women’s lightweight boxing competition were ended, losing to Sudaporn Seesondee on split decision.
However, Pat McCormack is guaranteed a medal when he takes on Ronel Iglesias in the men’s welterweight final.
