• Overview

  • Developed by Sean Mattison for Von Sol surfboards, the FCS VS KNUBSTER is essentially a center fin that can be added to any quad set-up

  • The fin will increase drive and provide directional control through turns, without sacrificing speed, flow, or the freedom of movement typically associated with a quad.

  • The “KNUBSTER” is designed with a single tab that allows the fin to be positioned in the forward and rear center plug to cater to the individual drive requirements of each surfer.
