Waterskiing is a sport where an individual is pulled behind a boat or a cable ski installation on a body of water, skimming the surface.First experimentations of waterskiing began in 1920, on the lake of Annecy (Haute Savoie), in France. Then, it really started on June 28, 1922 by eighteen-year-old Ralph Samuelson of Minnesota. Samuelson thought that if one could ski on snow, then one could ski on water. Samuelson s first attempt at waterskiing was on Lake Pepin in Lake City, Minnesota. They experimented with different positions on the skis for several days until July 2, 1922. Finally, Ralph discovered that leaning backwards in the water with ski tips up and poking out of the water at the tip led to successful waterskiing. He was towed by his brother Ben and they reached a speed of 20 miles per hour. Samuelson also achieved the first ski jump on July 8, 1925.
