Developed by Sean Mattison for Von Sol surfboards, the FCS V.S. 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 for the individual drive requirements of each surfer. Ideal in a wide range of conditions from beach breaks to point breaks.
