Catch Surf Beater Single Fin Kit

"You have to be careful because the leading edges are sharp! If you're light enough to dropknee or even stand-up ride, you'll appreciate what these can do for your ride when you go back up the face and off the lip. Make sure of your alignment when you install or you'll just increase drag without improving turn performance. Install them about an inch from the outside rail and bottom of the tail to ensure stiffness in the foam core for storing the energy for the turns."
