Water skiing (also waterskiing or water-skiing) is a water sport in which a person is pulled behind a motorboat over water, skimming the surface on two skis or sometimes one ski. It is most common to do on lakes, but can also be done in rivers and oceans.
In the United States, there are over 11 million water skiers.[1] In Australia, there are 1.3 million water skiers.[2]
