FCS Knubster Black Center Keel

The FCS Knubster Center Keel

The FCS VS Knubster is a center fin built to add to any quad fin setup. It increases drive and gives you more directional control through turns, without sacrificing the speed, flow, or freedom of movement that a quad setup is known for.

Built to Adjust Your Drive

The Knubster is designed with a single tab that allows the fin to be positioned in either the forward or rear center plug, so you can dial in the amount of drive to match your own surfing.

Who This Fin Is For

The Knubster is built for quad riders who want the option to add a fifth fin when they need extra drive off the bottom or more hold through a turn, without giving up the loose, fast feel a quad setup is chosen for in the first place.

Installing the Knubster

This fin fits the FCS II Fin System when used with grub screws and the FCS Infill Kit. Make sure the fin is seated fully before you paddle out, and rinse the fin and fin box in fresh water after each session to keep the plug free of sand and salt.

Part of the FCS Fin Family

FCS designs its fin range, including the Knubster, in collaboration with the world's leading surf athletes and surfboard shapers, and its fins remain a preferred choice among top surfers and shapers across a wide range of board models and conditions.
