IN shifty Biscayne Bay conditions, Giles Scott, Bryony Shaw and the 470 pairing of Luke Patience and Elliot Willis took home the yellow jerseys after day four of the ISAF Sailing World Cup in Miami yesterday.

Weymouth’s Scott pulled away from Australia’s Jake Lilley in the heavyweight Finn class with a 3,1 on the scorecard from his two races.

Weymouth-based Shaw remains in control in the RS:X women’s windsurfing event with a 21 point margin over the Netherlands’ Lilian de Geus as the British sailor aims to defend her 2014 crown.

Portland-based Patience and Willis extend their lead to 15 points at the top of the 470 Men’s leaderboard.

They used up their discard in the first race of the day when, along with their key rivals, they got caught out in a wind shift off the start line.

But the duo hit back in style in race two to take the gun and ensure they’re wearing the yellow jerseys for another day.

“We’ve been incredibly consistent which has been very good. We’ve had one slip up, which is our discard – that means we’ve got no more room for error and every point counts from now on,” explained double world champion Willis.

Weymouth’s Nick Dempsey picked up a black flag starting penalty and an 18th place to see him slip to fourth with two days to go.

Today sees the conclusion of racing for the three Paralympic classes, in which British sailors endured mixed fortunes yesterday.

A great start to the day for Portland’s Megan Pascoe in the 2.4mR fleet took a downward turn when the defending champion followed her race win up with another – only to find she had been penalised for being over the start line early. She is now in second, a point behind Norway’s Bjornar Erikstad, with two races to go.

SKUD duo Alexandra Rickham and Niki Birrell, who train at the Weymouth & Portland National Sailing Academy, improved on their overnight position with a race win and two seconds seeing them into overall second place.

Charlotte Dobson and Sophie Ainsworth enjoyed a great day on the 49erFX course to boost them into overall second place behind New Zealand’s Alex Maloney and Molly Meech, who have amassed an impressive 56 point lead with two days of the regatta left to run.

Hannah Mills and Saskia Clark hold on to their second place in the 470 Women’s class with 7, 11 from their two races today, while Sophie Weguelin and Eilidh McIntyre had a tough day at the office and dropped to fifth overall, with a 16,19.

2014 World Championship bronze medallist Nick Thompson remains in relaxed mood, with a fifth and a twelfth amid some tough Laser racing, seeing him into pole position with a ten-point lead with two days of the regatta left to run.

The final medal races for the Olympic Classes take place tomorrow.
