However, while most of them are quite fast on land, they move quite slowly when they are functioning as boats. The, only truly amphibious vehicle that cap move with equal ease on both land and water, is the Hovercraft. A Hovercraft actually travels on an air cushion produced by a large fan which blows air downwards between the body of the vehicle arid the water or the ground. This lifts up the craft. Because the Hovercraft floats on the air cushion; there is no contact between the craft and the surface below. This allows it to travel over flat or rough ground, or water.
