Category: Discovering Hovercrafts
A hovercraft (air-cushion vehicle, ACV) is a craft capable of traveling over land, water, mud or ice and other surfaces both at speed and when stationary. They operate by creating a cushion of high-pressure air between the hull of the vessel and the surface below. Typically this cushion is contained within a flexible "skirt". Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel. They typically hover at heights between 200mm and 600mm above any surface and operate above 20 knots and can clear gradients up to 20 degrees.
