That would be a hovercraft. However, hovercraft are not really boats and can travel on both land and water.
A vehicle that travels over water or land on a cushion of air is called a hovercraft
A hovercraft or air-cushion vehicle (ACV) is a craft designed to travel over any ... in their ability to travel equally well over land, ice, and water
The air cushion beneath the hovercraft reduces friction with the water, allowing the vehicle to move quickly on the surface. This cushion of air creates lift and buoyancy, enabling the hovercraft to glide over the water with minimal resistance.
A hovercraft floats on a cushion of air created by a fan or propeller underneath the craft. This cushion of air reduces friction between the hovercraft and the ground, allowing it to glide smoothly over surfaces such as water, ice, or land. The pressure from the cushion of air supports the weight of the hovercraft, enabling it to "float" above the surface.
Hovercraft
No, a hovercraft is not an airplane. a hovercraft is a craft capable of moving over water or land on a cushion of air created by jet engines.
A hovercraft reduces the effects of drag between it and the water by creating a cushion of air underneath it. This cushion of air lifts the hovercraft slightly above the water's surface, reducing friction and allowing the craft to move more easily and efficiently.
it rides on an air cushion so it can go on water, land, snow ect.
Hovercrafts float on a cushion of air created by a large fan or impeller underneath the craft. This cushion of air reduces friction with the surface, allowing the hovercraft to glide smoothly over land or water. The airflow is directed downward, creating enough lift to support the weight of the craft.
An air cushion in a hovercraft helps to lift the craft above the surface using high pressure air. This reduces friction and allows the hovercraft to move smoothly over flat surfaces like water or land. The air cushion also provides stability and control during navigation.
It operates across any surface (land or water) on the principle proposed by British Engineer Christopher Cockerell in 1950. The hovercraft is propelled by an air-screw and rides on a cushion of air. This cushion is trapped between the hovercraft's hull and the surface of the water or land below it by a flexible skirt usually made of heavy duty neoprene. The flexible skirt also enables the hovercraft to surmount any obstacles encountered on its voyages.
