Britain’s Scott, who won gold at the Rio 2016 Olympic Games, dominated the opening day but after two more races in the Polish city, he now finds himself behind Spain’s Muscat.

Hungary’s Zsombor Berecz climbed to third place while Spain’s Joan Cardona and Switzerland’s Nils Theuninck boosted their hopes with race wins today.

The day was sailed in 10 to 13 knot winds with low cloud but ended with a rain shower that affected the end of race four.

After a short postponement, race three got away first time with competitors on the left side of the course profiting from a huge shift.

Argentina’s Facundo Olezza rounded first from Cardona and Turkey’s Alican Kaynar.

Going downwind, Cardona then split the gate with Olezza before emerging ahead at the second top mark to take the victory from the Argentinian and Muscat.

The wind dropped slightly for race two with some low cloud appearing from the direction of Gdansk.

Theuninck reached the top mark first, but the Netherlands’ Nicholas Heiner was faster and got round the outside to lead downwind with Cardona in third.

However, Theuninck had the lead by the gate and did not let it go as Berecz rose to second and Scott took third.

Cardona, the defending under-23 European champion, produced the best score of the day after finishing first and second to climb to fifth overall.

"Today was quite a tricky day and I managed to come home with two top five finishes, so I am very happy to stay consistent on a difficult day," Cardona said.

"The last race at the end of the second upwind we had the shift from the right, but the guys who were in front stayed in front so it didn’t really change anything.

"It was not the best race, but I still managed to finish fourth, so I am happy."

Theuninck moved up to fourth overall after coming sixth and first in the two races.

"I had a good day," Theuninck said.

"Today was pretty tricky with a lot of rain clouds coming through and the second race we had a big shift, but I managed to deal with it nicely and take the win.

"Over the summer, I have been training a lot in Holland with Nick Heiner, so that’s been really good. But I am really happy to be racing again and doing something different from only training."

The competition, which was originally scheduled for July but postponed due to the COVID-19 pandemic, is set to continue tomorrow.
