Hydro-foils are a crucial component of numerous vehicles that glide above the water's surface. However, there are several synonyms for this term. Some other names for hydrofoils include winged boats, hydroplanes, water wings, flicker boats, and foilers. These names each describe the unique function of the technology, which involves lifting the vessel onto the surface of the water and minimizing friction while in motion. Hydrofoils were first used to break speed records, but they have since become essential technology for many vessels, including passenger and cargo ships, as well as military craft. Regardless of the name, hydrofoils are essential for efficient transportation over water.
