Kneeboarding is a discipline of surfing where the rider paddles on his belly into a wave on a kneeboard, then rides the wave face typically on one or both knees. The typical kneeboard is about five feet in length, with a wide round nose and constructed of GRP over a polypropylene foam core. Modern kneeboards have a rubber pad for the rider's knees, and often are equipped with a rope handle on each side of the deck to help the rider maintain control. Kneeboarders also typically use swimfins and an ankle surfleash.

The advantage of kneeboarding seems to be the ability it gives the rider to deal with tube rides that might require too quick of a set up for a bodyboarder to get into, but might get too tight or steep for a stand-up board surfer to deal with. It seems that kneeboarding is where the best of the skill sets unique to each of the surfing disciplines "comes together."
