Well I can see not many windsurfers have a knowledge about the difference between the 2 model of Deboichet fins (SL1 and SL2). Or maybe the question is not so interesting in this forum (although when the time comes to buy a fin from Deboichet the question should arise). Plus some Drake fins are based on Deboichet design.
Anyway is there anyone who can at least post me some links where I can find some answers or discuss about this matter?
Thanks in advance for your time.
