FCS Knubster VS Surfboard Fin
$16.00
Add to Cart

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.


The FCS VS KNUBSTER, which is 3 3/4” by 2” high, was the 5th fin Kelly Slater used in his boards during the Quiksilver Pro in New York. According to Kelly’s report, “The KNUBSTER makes your quad set-up feel faster, smoother, and it adds a little more control. It just tightens everything it up a bit”.


Interestingly Kelly was riding the FCS VS KNUBSTER when he scored his two 10 point rides in 2011. The first at the Quiksilver Pro in NY where he performed one of the best airs ever seen in competition, and the second at The Rip Cur Pro in Portugal in heaving barrels.


Adding the FCS VS KNUBSTER to your quad set-up is an affordable way to add a new dimension


to your surfing. FCS recommends using the fin with the FCS K2.1 Quad.
