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.

FCS brings order to your fin collection with its practical systems. But that wasn't enough for the Australians. They decided to add a worthy filling to their fin boxes. Superb fins, leaches and surfboard bags make the brand the first choice for surfers and shapers across the globe.
