The Greenough Knuckle...


Taking a page straight out of traditional boat design, one of George's design premises is a "knuckle" in the front 1/3 of a board's rail line.

Not to be confused with the more simplistic "flip" rocker concept, knuckle is a sharp break concentrated in the rail rocker line. It's intended to penetrate the water when the rail is sunk into turn.

Whereas flip is a defensive design element intended to keep the board from pearling, knuckle is an aggressive design element intended to let the rider bury the nose without sticking.
