Water skiing is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on two skis or one ski. The sport requires sufficient area on a smooth stretch of water, one or two skis, a tow boat with tow rope, three people (depending on state boating laws), and a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance. Skiing is a fun pastime that allows people of all skill levels and ages to enjoy. There is no minimum age necessary to water ski.
There are water ski participants around the world, in Asia and Australia, Europe, Africa, and the Americas. In the United States alone, there are approximately 11 million water skiers and over 900 sanctioned water ski competitions every year. Australia boasts 1.3 million water skiers.
There are many options for recreational or competitive water skiers. These include speed skiing, trick skiing, show skiing, slaloming, jumping, and barefoot skiing. Similar, related sports are wakeboarding, kneeboarding, discing, tubing, and sit-down hydrofoil.
