Fin specifications

We’ve compiled the fin specifications tables below to help you choose the right fins for you board . We have also compiled a SIZE GUIDE, TUNING GUIDE and FIN GUIDE to help you pick the right windsurf fins.

TT = Tuttle head, PB = Power box head, MT = Mini-tuttle head,  SB = Slot box head, US = US head (length in brackets)

All fin lengths in cm. All areas in cm². All weights (g) are approximate due to head variations.

DF = Dynamic Flex – Black Logo, SS = Super Stiff – Red logo. (Super stiff material 15% heavier than Dynamic Flex)

RAKE = The angle the fin leading edge (at the base) is tilted back from the vertical.
