A wave pool is a swimming pool in which there are artificially generated small and large waves, like we see in an ocean. The hydrofoil wave pool uses a galvanised steel blade (similar to an aeroplane wing) that is pulled underwater along a track, powered by a gearless drive system, down the side or middle of a body of water. When pulled, the submerged foil displaces the water and pushes out a wake that forms a wave.
