Kneeboarding...
Is an aquatic sport where the participant is towed on a buoyant,
convex, and hydrodynamically shaped board at a planing speed, most
often behind a motorboat. Kneeboarding on a surf style board with fin(s)
is also done in waves at the beach. In the usual configuration of a towsport
kneeboard, riders kneel on their heels on the board, and secure
themselves to the deck with an adjustable Velcro strap over their thighs.
Most water ski kneeboards do not have fins to allow for easier surface
spins. As in wakeboarding or water skiing, the rider hangs onto a towrope.
The advantages of kneeboarding versus other tow-sports seems to
be an easier learning curve and a sense of being closer to the water when
falls occur.
