K4 SUP Race Fin – 21cm

K4 SUP Race Fin – 21cm

Size: 21cm – 210 area – 215g

Our 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. (Fins with flex are always faster than stiff fins when the loads and AOA are low)

Already proven on the SUP race course with Andre Le Geyt finishing 7th in the 11 Cities.
