Wakeboarding

Wakeboarding
Wakeboarding is a surface water sport which involves riding a wakeboard over the surface of a body of water. It was developed from a combination of water skiing, snow boarding and surfing techniques. The rider is usually towed behind a motorboat, typically at speeds of 17-24 miles per hour, depending on the water conditions, board size, rider's weight, and rider's comfort speed. This speed can also depend on the year, make, and model of the boat because some boats, not meant for wakeboarding, produce a different size wake that may not be adequate enough for the rider. But a wakeboarder can also be towed by other means, including closed-course cables, winches, PWCs, trucks/cars, and ATVs.
