K4 Race Paddleboard SUP Fin US Box 21cm and 24cm

Swept back SUP race fin.
45 degree rake so you don’t have to worry about weed or debris.
Foil optimised for paddling speeds, but taking many pointers from our speed windsurfing fins. In fact I stuck this yellow fin in my windsurf and did 48mph on it!
Dynamic Flex material gives more grip, better tracking and more speed than stiffer materials.
An already proven SUP race fin can also be used on windsurfers with US box as a weed fin.
