    Got an old single fin with what's described.. Any good solutions for filling the gap so it's responsive?

    I had same issue with a single fin I had. Took a hi-tech approach and put a single strip of duct tape around base of fin. Fixed the problem surprisingly well.

    For a permanent fix, you can lam an equal number of layers of scrap 6oz glass on each side, doing one side at a time. Trim overhanging glass with razor blade when at the B stage, block sand to fit.

    yep, the Monster and LBCrew are spot on. Guys back in the old days (BT: "Before Thrusters") with single fin boxes would put a thin strip of duct tape on both sides of the base. Works surprisingly well. But, if you wanna do it *right*, LB's suggestion is the correct way.
