K4 Rockets Slot Box Windsurfing Fin
K4 fins have created a unique and new material for windsurfing. OptoFlex is a molded resin long fibre matrix that has been carefully manipulated to provide the perfect flex patterns for windsurfing. Our K4 technicians took a long time to create the perfect material with the qualities needed to provide the performance we now appreciate. Lighter, snappier and with outstanding flex memory
The Rocket wave fin. Almost like having slalom fins in your wave board! Lift, drive and speed for onshore conditions. Great for early planing and jumping. Also surprised us with their DTL performance but you’ll need to use your rails for powerful turns as they don’t have the same grip’n’whip in big cut backs and snaps as with the flexier fins.
