A kneeboard is a board ridden in a kneeling stance. Kneeboards are ridden in ocean surf, or while being towed behind a boat on a lake or river. Kneeboard riders generally wear life jackets or wet suits and catch the wave by paddling and kicking or dipping their hand in the water . Advantages to kneeboarding include an extremely low center of gravity, less wind resistance, the ability to ride higher and farther back in the tubes, and taking off on a steeper part of the wave. A pair of knee boards is also a tool used by a mason to distribute body weight while kneeling on wet concrete.
