hydrofoil

Noun

/ˈhaɪ.droʊ.fɔɪl/

A hydrofoil is a type of boat or watercraft that uses wing-like structures to lift the hull above the water at speed, reducing drag and allowing for faster movement over the surface.

Examples

The racing boat had hydrofoils that allowed it to skim over the water.
Hydrofoils are used in many modern ferry designs for increased efficiency.
Some recreational crafts now utilize hydrofoils for a smoother ride.

Meaning
