Britain’s Giles Scott made the most of the sole finn race to take the lead in the class on the penultimate day of the Sailing World Cup leg in Weymouth and Portland as a lack of wind continued to affect proceedings.

The four-time world champion had been hoping to compete in three races during the day as he looked to overhaul his team-mate Ben Cornish.

Only one race proved possible due to the weather conditions, but 28-year-old Scott earned the victory to move one point ahead of Cornish heading into tomorrow’s medal race.

Further home success looks likely in the Nacra 17 event, after Ben Saxton and Nicola Groves opened up a seven-point advantage over Germany’s Paul Kohlhoff and Carolina Werner, who booked their place at Rio 2016 with their performance.

The pairing were able to win both races to take full control of the overall standings in the fleet, with the top 10 boats all advancing to tomorrow’s single race.

New Zealand's Alex Maloney and Molly Meech were able to put pressure on the British crew of Charlotte Dobson and Sophie Ainsworth in the women’s 49erFX class, after the Kiwi duo finished first, second and third in the races contested.

However, two victories coupled with a sixth place kept the British pair two points clear of second place Swedes Julia Gross and Cecilia Jonsson, as well as a further five ahead of Meech and Maloney.

New Zealand's Logan Dunning Beck and Jack Simpson, though, will take a comfortable 14.50 point lead into the final race in the men’s 49er competition, with Lukasz Przybytek and Pawel Kolodzinski lying in second.

The tightest event heading into tomorrow are both 470 classes, with home favourites Luke Patience and Chris Grube tied for first place in the men’s standings with Spain’s Jordi Xammar and Joan Herp.

Both crews lie on 24 points each, after the Spanish crew picked up one victory and two second place finishes today.

Switzerland's Linda Fahrni and Maja Siegenthaler are tied for first place in the women’s competition, along with Britain’s Hannah Mills and Saskia Clark.

The men’s RS:X competition will see Germany's Toni Wilhelm lead China’s Chunzhuang Liu by three points heading into the final day, while Liu’s compatriot Peina Chen leads Britain’s Emma Wilson by 10 points in the women’s event.

Dutch sailor Marit Bouwmeester leads the laser radial classification by 13 points from France’s Mathilde de Kerangat, while Britain’s Nick Thompson holds a one point advantage over Australia’s Tom Burton in the laser class.
