Hovercrafts can travel over mud, swamps and, generally, wherever the ground is too soft to take conventional vehicles.

A feature specific to the hovercraft is its air cushion. The hovercraft is the best known application of the air cushion technique. The low pressure applied by the air cushion makes this vehicle virtually independent of any surface it travels over.
The hovercraft is a vehicle that has a surface area that is sufficiently extensive for supporting its weight at a low air pressure.
