My Boat

"You can get this boat straight out of the box and go and win races. It's about the reward and satisfaction of racing at the highest level."

Dave Swete — Founder, Cape31 UK · 31 North Yachting

"I'd never sailed before my first Cape31 season. Led the circuit in my third."

Ben Pritchard — Akheilos · Hull 53

"Britannia Cup. Queen's Cup. NYYC Challenge Cup. Cowes Week 2025. The smallest boats in the fleet."
