MFC K-One Wave US Box Windsurfing Fin
MFC K-One Wave US Box Windsurfing Fins 2014
MFC and Kevin Pritchard, former wave world champion, developed this new fin concept also in G-10 construction. The straight outline allows for very early planning and radical upwind ability, but the fin is incredibly maneuvrable due to its narrow outline and cord.
The profile is the fastest, generated by our KPR model and adapted to this wave model. Ideal for all around wave conditions can be use also for freewave conditions.

K4 BUBBLE FREESTYLE WINDSURFING FIN POWER BOX
K4 BUBBLE FREESTYLE WINDSURFING FIN POWER BOX
Our Freestyle fin developed by Andy ‘Bubble’ Chambers. We originally had two very different prototypes; one worked great on flat water but would spin out in the chop, the other was rock solid in the chop but too grippy on flatwater. The BUBBLE freestyle fin has the perfect blend of grip to be secure in the chop and into carving manoeuvres, whilst still allowing plenty of release for double spins.

K4 Fang Freeride Windsurfing Fin Tuttle Box
K4 Fang Freeride Windsurfing Fin Tuttle Box
Developed with help from the Official Test Centre Weymouth. This fin is the culmination of years of R&D with new materials and new fin designs. We made numerous prototype moulds and moulded them in several materials until we found the best combination. We then refined the prototypes to arrive at the Fang Freeride. A fin that will give you amazing speed and control, secure carving and let you fly upwind. The material is K4’s ‘Super Stiff’, the ideal composite for Freeride fins; great reflex, stiff enough for excellent acceleration and direct response, enough flex for speed, grip and control.
