Fin systems

US Fin Box System

The US box system is tried and tested and was already used in windsurfing boards in the 90s. You can recognize the US finbox system by the groove stone, which you first insert into the guide rail. Then the fin is inserted and screwed tight with a separate screw. The advantage of the US box system: You can position the fin differently in the fin box. The disadvantage: you can easily lose the groove stone and screw.
