Surfing is a surface water sport in which the surfer rides a surfboard on the crest and face of a wave, which is carrying the surfer towards the shore. Waves suitable for surfing are found primarily in the ocean, but are also sometimes found in lakes and rivers, and also in manmade wave pools.
Windsurfing or sailboarding is a surface water sport that combines elements of surfing and sailing. It consists of a board usually two to four metres long, powered by the orthogonal effect of the wind on a sail. The rig is connected to the board by a free-rotating universal joint and comprises a mast, wishbone boom and sail. The sail area ranges from less than 2.5 m2 to more than 12 m2 depending on the conditions, the skill of the sailor and the type of windsurfing being undertaken.
