Delpero overtakes younger brother Edouard in the regional rankings to be crowned European Longboard Champion, while Alice Lemoigne (REU), 18, eliminated in the Semis, belts second European title watching the women's Final from the sand.
Delpero and Timothee Creignou (FRA), 29, started their Final with an exchange going Delpero's way with an excellent 8.10 over Creignou's 5.50. Delpero continued to build momentum and belted a 9.40 to put his opponent in a combination situation he would never recover from.
"I'm super happy, that was a dream Final against my good friend Tim," Delpero said. "Conditions today were absolutely perfect for longboarding and we all were able to display our best surfing out there. I started with good waves early and that made Tim's job pretty hard. I'm stoked to clinch the European title as well."
Delpero previously dispatched of younger brother Edouard in the Semifinals with a buzzer-beater, near-perfect score of 9.93. Both Delpero brothers will represent Europe at the upcoming World Longboard Championship in China.
"I don't have a particular preparation for this event, but we're starting to know the wave well at Riyue Bay," Delpero continued. "I was a little frustrated last year when I got a 10 and couldn't back it up."
Creignou, former Semifinalist at the GoPro World Longboard Championship in 2014, couldn't overcome Delpero's rhythm but kept his composure in a difficult situation to keep improving his scoreboard throughout the Final.
"Timing was perfect and we really finished the event in the very best conditions," Creignou said. "I would have loved to win here. It's a great warmup for China and we're going to have a good team there. We want to keep showing that French and European longboarders are relevant."
A slow first half of the women's Final saw Vergara and Justine Mauvin (REU) exchange medium waves and average scores before Mauvin caught the first major wave with a long hang five all the way from the outside for a 7.17. Vergara answered shortly after with a 7.57 and kept things interesting for the crowds.
Both surfers went blow for blow on a succession of exchanges with Mauvin taking the lead back on an 8.27 before Vergara, with two minutes remaining, started a ride with a beautiful hang 10 followed by a couple of turns for the winning 8.40 ride.
"I gave everything I had and was a little bit lucky," Vergara said. "It's cool to surf here with friends and family being able to come support and watch us perform. We have two months now to train for China. I can't wait to go there again and hope I can better my ninth place from last year."
A Finalist in the opening event of 2015 in Newquay, Mauvin was one heat away from clinching a maiden regional title, but couldn't overcome Vergara's poise and grace in the clean peaks of Vieux Boucau in the Final.
"That was a fine day of surfing with good friends in super fun waves," Mauvin reflected. "We both got good scores and it came down to almost nothing. We did our best and really enjoyed competing and putting on a good show. I'm going to keep training, improve and hopefully be ready for China."
The European team going to the World Longboard Championships in China will be comprised of Antoine and Edouard Delpero, Timothee Creignou, Ben Skinner (GBR) and Adam Griffiths (GBR) for the men, and Vergara, Mauvin, Alice Lemoigne (REU) and Lucie Milochau (FRA) for the women.
