I recently bought a 11’0 Island Glass board and it seems to have a lot of side to side wobble. Right now the board has a single fin on it but its a 2+1. Will adding side fins increase stability? Also, if it does. What size would you recommend? Single fin is a 10” nsp one that the guy had thrown in with the board.
I also used the search to no avail
