Parlier produced a series of strong races in the men’s competition, with 87 competitors having been split into three heats.

The Frenchman triumphed in all four of his heats to leave him top of the standings on three points, with one result discarded.

He is followed by the British duo Olly Bridge and Connor Bainbridge, who were in the same fleet at the Italian venue.

Both athletes claimed one win and two second-place finishes, which left them one point shy of Parlier.

France’s Théo de Ramecourt earned two wins in his fleet, while compatriot and former world champion Maxime Nocher claimed one triumph.

With one of their results discarded, the Frenchmen lie on five points after the opening day of racing.

She has three points, with Russia’s Elena Kalinina placed second on six.

The top three is completed by Australia’s Breiana Whitehead, who has 14 points.

The Championships are set to continue until Saturday (May 4).
