Theo de Ramecourt of France got the better of countryman Benoit Gomez in the Formula Kiteboard discipline of the Trofeo Princesa Sofia Mallorca in Spain while racing continued in nine other disciplines.
The Bay of Palma produced perfect conditions for the fourth day of competition as Gomez powered to victory in the opening heat in the Formula Kiteboard.
However, he was unable to maintain his form as De Ramecourt mastered the wind to take the next four heats which puts him three points ahead of his compatriot in the rankings while Slovenia's Toni Vodisek makes up the top-three, seven points off the lead.
"The wind and the waves were super-tricky, and it was very technical upwind and downwind, easy to lose control," said De Ramecourt.
"At the start of one race Toni got in front of my line just before the gun, so I had to stop and wait to get going.
"But it was a fun mission to play catch-up."
France are also excelling in the women's Formula Kiteboard event with Lauriane Nolot extending her lead over Britain's Ellie Aldrige to 11 points.
