Thats a massive fin 6m; 10-15knt... maybe something around 35 Freeride fin on a board that size?? I learnt with a 33 plastic weed fin on my 165L and that was plenty. Whats the rule? (Sail size x 5) +3 something like that.
Thanks - wasn't sure if 33 or 35 would be too small.
Fin i got seems to be alright, but i haven't tried any to compare, just so long.
Starboard website has 2 fins (maybe) it says come with the board - Deep Tuttle Drake R13 Race NR 520 + Drake Shallow 410 on Tufskin model - sail range 5.5-9.5
I think if you are under finned you better be overpowered a bit with the sail and visa versa, if your fin is a bit too big you better not be overpowered with the sail.
