SIDE FIN Pair Rigid Reverse attachment fins for US sliding fin box

Reverse attachment so you cn move the fin even further forwards in the fin box.

Single Foiled.

Designed for the US sliding fin box system, the MACSKI SURF Custom Rigid CENTRE Fin delivers precision performance shaped exactly to your specifications — drawn up on CAD and CNC-cut.

The US box system gives you the flexibility to adjust your fin position for different wave conditions, while rigid fibreglass construction ensures optimal flex under load. The result: maximum power transfer, sharper turns, and explosive drive off the bottom.
