Olympic champion Picon's lead was shortened after a solid, yet unspectacular, third day. 

Despite finishing first in her opening race, she then placed fourth and ninth in her last two races of the day and now has a net points total of 24. 

Britain's Emma Wilson was the big winner today, moving up to second following two podium finishes.

Now on a total of 29, Wilson placed third in her opening race, before winning her eighth and taking seventh in her last of the day.

She sits three points ahead of Poland's Zofia Noceti Klepacka, who won the final race of the day, now sitting on a total of 32.

Israel's Katy Spychakov fell to fourth after failing to make the podium today, leading her to discard her eighth race, and putting her on a score of 35.

World champion Lilian De Geus of The Netherlands lost touch in fifth after a disastrous final race of the day saw her disqualified, forcing her to discard that performance and giving her a total of 46 points.

Others who made the podium today were sixth-placed Israel's Maya Morris, eighth-placed Marta Maggetti of Italy, 10th-placed Maja Dziarnowska of Poland and 11th-placed Roy Drihan of Israel.

Cohen's day was his worst yet, but he still held a strong lead over the rest in the men's fleet.

Discarding his seventh race after finishing 13th, the Israeli then finished sixth and seventh, now sitting on a total of 35.

This allowed the challengers for the gold to close the gap and Greece's Byron Kokkalanis is the closest to him at the moment with a score of 43.

Finishing fifth in his opener of the day, two third place finishes helped him to reel in the leader.

However, another Israeli is close behind, having had similar success to the Greek.

Shahar Zubari finished third, fourth and fifth to bring his total up to 47, while world champion Kiran Badloe of The Netherlands had a near-perfect day, winning his last two races and finishing second on the opener.

Having suffered in his opening four races, Badloe is now in fourth on a total of 53, overtaking France's Tom Goyard today who now sits fifth on a total of 57.

Britain's Tom Squires could be a late contender for a medal too after winning the first race of the day and finishing second in the next.

He now sits in seventh on 61 points, a point behind Israel's Yoav Omer.
