More Information

Developed by Sean Mattison for Von Sol surfboards, the FCS VS Knubster is essentially a centre 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 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 centre plug to cater for the individual drive requirements of each surfer.
