3 KINDS OF HIGH SPEED VESSEL

A Hovercraft, also known as an air-cushion vehicle or ACV, is a craft capable of travelling over

land, water, mud or ice and other surfaces. Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel. Hovercraft use blowers to produce a large volume of air below the hull that is slightly above atmospheric

pressure. The pressure difference between the higher pressure air below the hull and lower

pressure ambient air above it produces lift, which causes the hull to float above the running surface.

A hydrofoil is a lifting surface, or foil, which operates in water. They are similar in appearance and purpose to airfoils used by airplanes. Boats using hydrofoil technology are also simply termed hydrofoils. As speed is gained, hydrofoils lift the boat's hull out of the water, decreasing drag and thus allowing greater speeds.

A submersible is a small vehicle designed to operate underwater. The term submersible is often used to differentiate from other underwater vehicles known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word submarine may be used to describe a craft that is by the technical definition actually a submersible.
