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, snowboarding 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, type of tricks, and rider's comfort speed. This speed could also depend on the year, make, and model of the boat because some boats, which are not designed for wakeboarding, create a different size wake which the rider may not feel comfortable with. But a wakeboarder can also be towed by other means, including closed-course cable systems,[1] winches, personal water craft, trucks/cars, and all-terrain vehicles. Most wakeboarding activities are usually done in lakes, but more and more wakeboarding locations are also popping up along the coasts. Wakeboarding in the ocean is a more challenging activity because of the amount and strength of waves. This requires more balance, control, and physical conditioning on the wakeboarder's part to tame the waters.
