Who It Is For
This is the small size, built for riders in the 105 to 155 pound range.

Installing and Caring for Your Fins
- Confirm your board uses a compatible Futures fin box before installing
- Hand tighten the fin screws snugly, then recheck them after your first few sessions
- Rinse the fins and fin box with fresh water after every surf to clear salt and sand
- Keep the recycled NetPlus material out of prolonged direct sun when the board is stored
About Futures
Futures was started in 1996 by the Longo brothers, who had previously worked on aerospace parts and hydrogen fuel cell fabrication before turning their technical background toward surfing and fin design. The Alpha line pairs that engineering background with Bureo's recycled fishing net material.
