Wakeboarding is a surface watersport activity which involves standing on a wakeboard while holding on to a rope and handle and being towed over a body of water. Invented from a collaboration of water skiing, surfing, and snowboarding, wakeboarding is usually towed behind a motorboat or a cable tow. The main objective while wakeboarding behind a boat is to carve from the outside of one wake, to the outsideof the other wake, while using the closest wake as a jump and the far away wake as a landing. Rope length is critical. and varies from boat to boat. As the wake "V"s out, The two wakes become further and further apart, requiring more speed and air time. The speed of the sport can vary from 14-25 miles per hour, depending on the wakeboarder's weight, the size of the wakeboard, and wakeboarder's skill and comfort level. The speed may also depend on the amount of weight in the boat, as well as the make and model of the boat. Some boats are designed for wakeboarding and create a larger wake in which the wakeboarder may not feel comfortable trying to cross. Wakeboarding doesn't have to involve a motorboat, it can also be towed by other means, including closed-course cable systems, winches, personal water craft, or Micheal Phelps.
