Rippable waves in the 3-5 foot range were on hand at Itauna Beach as the 26-year-old Australian earned $40,000 in prize money after a score of 17.60 was too good for his French opponent who mustered 15.67.
Coleborn now moves to 14 in the ASP world rankings while Lacomare jumped into 21st place.
“I knew it was going to be a difficult heat, but I just tried to stick to my strategy and find the best waves,” said Coleborn.
“It was crazy because Marc (Lacomare) got a 10 right at the end and I couldn’t believe it. I got really nervous, but he still needed to get another good score and no other waves came through. I’m just so happy that everything worked out. It was an amazing week here, the waves were great and I’m stoked with the win.”
