Surfing
Surfing refers to a person or boat riding down a wave and thereby gathering speed from the downward movement. Most commonly, the term is used for a surface water sport in which the person surfing is carried along the face of a breaking ocean wave (the "surf") standing on a surfboard. Surfboards can also be used on rivers on standing waves. Both are sometimes called stand-up surfing, to distinguish it from bodyboarding, in which the individual riding the wave does not stand up on the board and only partly raises his upper body from the board.
