Originally popular as glass-ons in the 1960's, now "D” fins can be put in fin boxes for variety. This beaut is made for long lasting noserides. The larger area on this fin allows the board to hold in the wave like nothing else. Try one on your log and take a trip to the past. The D-2 is 9.0” deep and has a 9.75” base.
This fin will just fit in the 10” standard fin box because we have made an overhang in the rear of the fin. You may have to take out your “fin box leg rope” but mostly we know D-fin riders do not use such newfangled attachments anyway.
