  • Will my screwing habits really stay about the same?

    Our screwing proclamation may be a little inaccurate. Some surfers may have to screw twice as much, and some will need to screw 6-8 times as much before surfing. Many surfer’s screwing habits will remain about the same. Your past screwing habits really do matter: Futures, glass-ons, Bahne, FCS.

  • Why don’t you have registration marks on the fin boxes and fins to help with fin positioning?

    We do. The checkers are a basic guideline to help with fin positioning. Just count checkers and half checkers from one end of the fin to the box edge. Because so many brands of fins can fit our fin boxes, we came up with checkers that can work as a positioning guide with any brand of fins. And checkers = speed.
