The M80 Stiletto is the largest U.S. naval vessel using advanced carbon-fiber and epoxy composite materials, which yield a light yet strong hull. These craft are expected to cost between $6 and $10 million US Dollars each. Rear view of M80 Stiletto during a training session with Navy SEALs, 2006.
The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats (see illustration). As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull ...
Hydrofoiling wingsail catamaran 17. A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull.As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed.
It is a rigid strut that extends obliquely upward from the boom to the mast, exerting a force that pushes down on the boom. As the fixing point of the gnav on the boom is hauled inwards towards the mast, the downward force on the boom increases. A gnav offers more uncluttered space beneath the boom when compared to a vang.
The hull is constructed in a fibre reinforced composite, consisting of a carbon fibre and foam core laminate with an epoxy glass and foam sandwich layup. The tubes are Hypalon. The boat is powered by twin 115 hp (86 kW) Yamaha 4-stroke outboard engines that have been inversion-proofed to ensure the engines are still operational after a capsize.

Wind-assisted propulsion is the practice of decreasing the fuel consumption of a merchant vessel through the use of sails or some other wind capture device. Sails used to be the primary means of propelling ships, but with the advent of the steam engine and the diesel engine, sails came to be used for recreational sailing only.
