Hydrofoil

Last crawled date: 3 years, 3 months ago

The hydrofoil is a particular boat that stops or low speed is held afloat by the hydrostatic thrust or the displacement (principle of Archimede). When it reaches a sufficient speed driven by an engine or sail, thanks to the bearing of particular immersed surfaces (wings connected to the hull) emerges completely, with consequent significant reduction of the advancing strength. Under these conditions, this boat can reach speeds of over 50 knots (92.7 km / h) with moderate energy expenditure. #hydrofoil
