K4 Fins Dugong Weed Wave

Dugong Weed Wave US Box and Slot Box head

9 - 17 cm 

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 fins are extremely robust too -we haven't had a single return through breakage.

We took the successful Rocket template as our starting point and looked to use over 38º rake whilst still maintaining performance. Our gut feeling was that the super stiff material would work exceptionally well for the weed fin, giving just enough flex to slip through the water with minimum drag but also enough stiffness to be direct and lively underfoot despite the reduced lift.
