Wakesurfing
Wakesurfing involves a surfer trailing behind a motorboat on a short surfboard that's about five feet (1.5 meters) long and literally surfing through the boat's wake without being attached to the boat.
Wakesurfing starts with a surfer lying in the water with his or her feet on the board, ready to quickly stand up. The surfer holds onto a towrope as the boat picks up speed, eventually topping out anywhere from 9 to 11 miles per hour. The surfer then jumps into a standing surfing position, drops the rope and surfs through the wake the boat creates.
