  • 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.

    • 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.

    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 👍🏽😊
