Fin Box for Mistral STS

[LakeSurf]

Alright, I'll sup with it first to see how it goes

My used board search has been pretty disappointing. There was 1 board that would have been perfect for me for $500. But it sold before the seller got back to me. There's barely wind here in the summer so I can't justify spending thousands to buy everything new and have it collect dust.

actually that fin was one of the first to avoid spin out - from what I read

i have used the fin on a Mistral COMP SST with NO difficulty of spin out
this is a sample in light winds (20-30 kph)
