Giles Scott ensured Team GB kept up their astonishing record in the men's Finn class as he sealed their fifth consecutive Olympic golf in the event.
Scott keeps Team GB unbeaten at the Olympics in the 21st Century
Since Sir Ben Ainslie retired from the sport after London 2012, Scott has dominated the last Olympic cycle with 16 wins in the last 18 regattas. He went into race nine and ten with the possibility of securing a deserved gold before the double points race on Tuesday.
Scott had a conservative start to the days sailing as he finished eighth in his first race of the day, but importantly stayed ahead of his closest rival Vasilij Zbogar of Slovenia. That result left Scott knowing that if he could repeat the feat he would win a maiden Olympic crown. Continually staying on the shoulders of the leaders, the Brit eventually sailed into second place, with Zbogar down in eighth, enough to secure the gold medal with a race remaining.
Dempsey cruises to silver
Despite double points being awarded in the medal race, a similar story had unfolded in the men's windsurfing. Dorian van Rijsselberghe had already secured gold before the race, whilst Team GB's Nick Dempsey knew a silver was certain to come his way. The pair could enjoy their final run without pressure, finishing in first and fourth respectively, whilst a seventh place finish for Pierre Le Coq wrestled the bronze medal away from World Champion Piotr Myszka.
Dempsey had conceded before the competition that at 36 years old this could be his final Olympic outing, though he could still make a surprise appearance in Tokyo after claiming "I am disappointed because I know I can beat Dorian van Rijsselberghe".
Picon takes gold in epic final windsurfing race
Another incredible story unfolded in the women's windsurfing. France's Charlie Picon found herself in fourth place going into the medal race but with just five points separating the top five. Picon sailed home in first place to take the gold medal, whilst China's Chen Peina followed her to upgrade herself from bronze medal position to silver.
Stefania Elfutina was the surfer to swap places with Chen and finish with the bronze medal, but it was a day to forget for Italy's Flavia Tartaglini who fell from the gold medal position to sixth after an eighth place finish. The legendary Lilian De Geus missed out on the medals by just one point.
All to race for in the Nacra 17 class
It was a busy day for the mixed Nacra 17 class who faced three outings on the water. After a disappointing start to the afternoon, Argentina's Santiago Lange and Cecilia Carranza Saroli took a second and a first to hold a five point advantage going into the medal race.
A second, seventh and fourth kept the Italian pairing of Silvia Sicouri and Vittorio Bissaro hot on their heels, whilst Austria's Thomas Zajac and Tanja Frank, followed by Australia's Lisa Darmanin and Jason Waterhouse will be fighting it out just two points behind each other respectively.
Another medal on the horizon for Team GB?
Both the women and men's 470 classes were scheduled for three races but could only fit in two as the weather eventually squeezed them out. Though it did not dampen the spirits of Team GB pairing Heather Mills and Saskia Clark as a win in race seven left them in gold medal position with four races to go. They are closely followed by Annie Haeger and Briana Provancha, but the two boats have clear air over the rest of the pack.
A third and fourth finish allowed the Croatian duo of Sime Fantela and Igor Marenic to continue their dominance with a 11 point lead in the men's event. Though the experienced Matt Belcher will not give up the race from silver medal position with his partner William Ryan.
