It is compatible with our Alpha 11’6, Alpha 12’6×31 and Alpha 12’6×28, Alpha 14′ models. You can also fit it in a US double rail on our foil boards, such as Sky Rider or Sroka Air, to enjoy your foilboard in surf and Stand up Paddle mode.

Built for speed and hiking
The U.S. fin is long and contoured to better cut through the water and stabilize you. Its shape helps you to balance on the board but also to keep your trajectory, allowing you to always go straight even when paddling only on one side, saving your efforts to take you further to new bodies of water.
