North Devon's Emma Fishleigh and Aidan Brackenbury have become multiple British surf kayak champions.
They won five titles between them at the British Open in Portrush, Northern Ireland.
And Aidan, 18, beat the reigning world champion to become the youngest winner of the men's long boat title.
He won the two junior classes with relative ease but his real success came in the men's competition where he managed a respectable fifth place in the short boat class and first place in the long boat.
"In the final I had the reigning and two former world champions, so to win was just brilliant," said Aidan, an apprentice at Babcock International.
"I'm really pleased at how I surfed through the whole contest. Surfing across the beaches of North Devon really prepares you for every type of wave you will encounter and I think that exposure has really helped me win these titles."
Emma, 24, an instructor at Skern Lodge Outdoor Activity Centre in Appledore, was a runner-up last year. She went one better this time to claim the women's title in both the short and long boat classes with fantastic performances against a strong field.
"I had an amazing weekend and I would like to thank everyone for all their support," said Emma. "I'm absolutely delighted."
The conditions were near perfect for the finals with clean 2 to 3ft waves allowing for some impressive surfing.
Surf kayak competitions have been run in the UK since the mid-Sixties and the first British championships were held in 1980.
It is a knockout competition where competitors surf 15-minute heats against three others. Their waves are judged on a points system with their two best scores making up their final total.
Both kayakers are sponsored by Braunton-based Reed Chillcheater who produce surf kayak equipment.
A statement from the company said: "It's fantastic to be able to celebrate the successes of home-grown talent competing at an international level.
"Emma and Aidan work hard at their sport and their dedication has paid off with well-deserved wins.
"They are wonderful ambassadors for Reed Chillcheater and for North Devon – we're proud to be their sponsors."
