Hydrofoil

A waterborne transport mode whose hull is fitted with underwater wing-like foils that generate lift as the vessel gathers speed, raising the hull clear of the water to cut drag sharply and allow faster, more fuel-efficient travel than a comparable displacement hull. Alexander Graham Bell's HD-4 set a world marine speed record of 114 kilometers per hour in 1919, and the Swiss company Supramar built the first commercially operated hydrofoil, the PT10 Freccia d'Oro, in 1952. Hydrofoil ferries have since served many short coastal and inter-island passenger routes where speed matters more than cargo capacity.
