Custom surfboard fins hand-shaped in Santa Cruz. Plus everything you need to learn the craft and build your own.
Mass-produced fins are designed for everyone, which means they're optimized for no one. A fin shaped by hand responds to the wave, the board, and the surfer in ways injection-molded plastic never will. Orions Fins exists because we believe surfers deserve equipment that's as intentional as their surfing.
Custom fins you can buy. Knowledge so you can build.
Hand-shaped singles, twins, and keels in fiberglass. Each fin is designed for a specific board, wave, and surfer. No two are the same because no two sessions are.
Step-by-step tutorials, material guides, template libraries, and video walkthroughs. From your first fiberglass layup to foiling a twin set. The knowledge shouldn't be gated.
A community of surfers who shape their own gear. Share templates, swap techniques, show off your builds. The craft gets better when the knowledge flows.
Start with a proven outline or design something new. Rake, depth, base length, and foil all get dialed for how you surf and what you ride.
Fiberglass cloth and resin, layer by layer. The panel cures overnight into a rigid blank that holds the shape and flex you're after.
Belt sander, hand sanding, hours of patience. The foil goes from flat panel to hydrodynamic surface. Leading edge, trailing edge, base to tip.
Drill, pin, polish. Test the fit in the box. The fin should slide in smooth and lock solid. Then it's time to paddle out.
Shaped in Santa Cruz. Ridden everywhere the swell goes. Orions Fins is where the craft of custom fin-making lives and grows.
