The pair combined to record a triumph, a ninth-place finish and another win in the mixed 470 fleet racing in Almere, which is located not far from Amsterdam.

"It was very shifty and gusty and the key was always to try to read the wind on the water," Berta said.

"The two race wins came from starting strongly and defending position against the fleet while trying to keep an eye on the ever-changing breeze."

Japan’s Keiju Okada and Miho Yoshioka claimed the other race win to establish themselves in fourth of the overall rankings.

Linda Fahrni and Cyril Schüpbach of Switzerland are second and Uma Chouhan and Ravindra Sharma of India are third.

World champion Odile van Aanholt and Tokyo 2020 bronze medallist Annette Duetz initially produced a stunning set of three wins from four in the 49erFX, but they were judged to have not taken the correct course in the opening race.

The decision meant the Dutch duo were handed with a 'did not sail' score, which is the equivalent to a disqualification.

Australian crew members Olivia Price and Evie Haseldine moved into top spot in the overall rankings due to the home favourites' mistake.

In the formula kite women, The Netherlands' Annelous Lammerts spectacularly claimed four victories from four as Israeli pair Maya Ashkenazi and Gal Zukerman came in second and third.

The men's event saw Benoit Gomez of France win the four heats in Blue Group while Dor Zarka of Israel and Riccardo Pianosi of Italy shared two wins each in Yellow Group.

Zarka is positioned second overall, which is one place in front of the 16-year-old Italian.

Ecem Guzel of Turkey and Louise Cervera of France are level on six points each at the top of the ILCA 6 and Laila van der Meer and Bjarne Bouwer of the hosts are one point ahead of Lukas Haberl & Tanja Frank of Austria.

The Netherlands' Max Castelein triumphed in the initial four races of the men’s iQFOiL.

Bart Lambriex and Floris van der Werken, also of the hosts, lead by two points in the men’s 49er.

The Hempel World Cup Series is scheduled to continue tomorrow with more qualifying races.
