      • Overview

        • 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 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 centre plug to cater for the individual drive requirements of each surfer.

        Ideal Conditions

        • A wide range of conditions from beach breaks to point breaks.

        Board Types

        • All board types.
        • Will fit the FCS II Fin System when used with grub screws and the FCS Infill Kit.

      • Thermo Polymer

        Really tightened up quad set

        Love/hate relationship with quad sets. Love the speed, but sometimes turns get squirreley. Dropped in the nubster and the board tightened up (in a good way) off the bottom and top while still maintaining the signature speed of a quad. Defiantly give one a try!

        Mini Keel Stabiliser

        This mini keel stabiliser has given my quad set up on my board a bit more control especially in punchy beach breaks !

        Worth having in your fin quiver!

        Riding 5 fins in the Cymatic. The knubster really adds some drive but keeps a nice pivot point as well 👍🏽😊

        Easy

        Easy process to order product and to follow its progress from start to finish. Using this little knubster for a timber hand plane that I have built. Hope to have it in the plane shortly ready for testing. If goes well I’ll be ordering more 🤙🤙
