Stardupp US box Fin allround

The Stardupp US box vin allround is made touring en race SUP boards. With this vin they used a stronger way of mounting. The fin is made with fiberglass reinforced nylon, this makes the vin strong and avoids bending.

A fin makes your iSUP go in a straight line. Without it your sup would turn more instead of pushing the sup in a straight line. This is why a good fin is always important.

suited for: all boards with a US-box Fin box
