After a long waiting I finally got my new boards. I'm writing again for the fin size for the isonic 127 and the RSR NP 9.5 sail. As recommended here in the forum I ordered and got a R16 50cm Deboichet but with a big surprire I found printed on the board that the recommended fin for a 9.6 sail is the 52cm and NOT the 50.
A fin cost more than 300$ and above all can takes months to have it.
So where is the mistake?
