TMF-1 trail fin

Futures Fins

The original Knubster was developed by Sean Mattison for Von Sol surfboards, the Futures TMF-1 (The Middle Finger) Knubster is a 5th. Fin 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 raked template with the extended length of the base provides increased stability for any board and works best in boards with larger tail areas.
