Grae Morris stormed into the lead in the men's windsurfing with his best performance on the water so far.
The Australian started with second in race seven and followed that up with a first and second in two later races to edge to the top of the leaderboard as the Opening Series passed the halfway mark.
Poland's Pawel Tarnowski held onto second spot with two strong fifth-placed finishes at the start of the day, which puts him just a point behind Morris.
Israel's Tom Reuveny completed the top three with mixed results, but a valuable third and fifth were enough to keep him in the hunt.
"It was not the best of days," said Reuveny.
"I had one BFD in the first race and a pretty bad race in the last one, but the results seem pretty ok."
"I'm still in the mix. Everyone had bad races, so it's a hard fleet, and everyone is sailing very well."
Unstoppable Emma
Emma Wilson kept her cool in the women's windsurfing to extend her advantage at the top of the standings.
After the Marathon Race had to be abandoned due to a lack of wind, the British athlete responded with three race wins, putting her 19 points clear of the rest of the pack.
Israel's Sharon Kantor is Wilson's closest competitor, and she was also the only other windsurfer to win today.
Italy's Marta Maggetti retained her place behind Kantor with three top-five finishes, keeping her firm in the hunt for a medal.
"I'm happy about the last Slalom course," added Maggetti.
"A bit exhausted as well. I'm happy, I'm staying focused, and my results are pretty constant, so I hope it stays like this."
"I really want to get a medal, so I'm happy I'm still close to this."
