This little fin is rad! Super stocked on the stability it gives when riding a twin fin! Overall sick product!
Can be added to any quad set-up. Increase drive and provide directional control through turns.
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.

This fin has done exactly what I had hoped it would, and what it is advertised to do. Great! I have two boards it gets used on. A large 7' fish-style with a four fin setup which just needed that little extra drive and stability from a small centre fin. Perfect. And a 6'6" high volume board that basically wants to be a twin fin but slides too much without a centre fin. The knubster only gets used on this board in small wave conditions, and again works a treat.
I’ve had knubster fins as a stabilisater in a few surf boards. They give a hint of stability without effecting the turning ability. I am using them in conjunction with fcs modern keel . It’s a good combination
