Yes, they do. For safety reasons and by design, when the skirt deflates, there is enough freeboard to keep the machine afloat.

How does a hovercraft float on a cushion of air?
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.
Who and when was the hovercraft invented?
The hovercraft is the invention of Christopher Cockerell. In 1956, he invented this vehicle that could move over water. The craft was designed to float on a cushion of air which required a mounted fan for power.
How does hovercraft float?
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.

Why does a hovercraft need fans to move?
A hovercraft needs fans to create a cushion of air underneath it, which reduces friction with the surface and allows it to float. These fans provide the lift necessary to keep the hovercraft afloat and enable it to glide smoothly over a variety of terrains, including water, ice, and land.
How does the hovercraft relate to newton's first law of motion?
The hovercraft demonstrates Newton's first law of motion, which states that an object will remain at rest or in uniform motion unless acted upon by an external force. In the case of a hovercraft, the air expelled downwards creates a force that propels it forward, allowing it to move over water or land without friction.
Why does oil still float after the stirring stops?
Oil floats on water because it is less dense. Even after stirring stops, the oil will continue to float due to its natural buoyancy. The difference in densities between oil and water prevents them from mixing.
How does Hovercraft moves?
A giant motor connected to a propeller to push the hovercraft across the ground or water.
Is a hovercraft like an airplane?
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.
What boat travels over water on a cushion of air?
That would be a hovercraft. However, hovercraft are not really boats and can travel on both land and water.
What happen when water enter aircaraft engine?
the car stops working
What enables a swimmer to float even though his body uncontrolled sink in water?
Motion, continous motionmakes it possible for the body to float. An example is the bicycle, when it stops its motion, it fall.
