Water ski jumping takes place on a pair of long skis with a tail fin attached. The skier is towed at speed to a floating ramp with the aim of launching themselves as far as they can through the air. They must then land and regain control of the rope. Three years after Ralph Samuelson invented water skiing, he made the first jump off a makeshift ramp. World Champion water skier Freddy Krueger is best known for his jumps. He holds the world record for the longest jump at 247 feet. This sport requires balance, strength and endurance and it featured in the 1972 Summer Olympics as a demonstration sport. .
