Developed by Sean Mattison for Von Sol surfboards, the FCS Knubster is essentially a center keel 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 for the individual drive requirements of each surfer.
