The US Navy began experiments with hydrofoils in the mid-1950s by funding a sailing vessel that used hydrofoils to reach speeds in the 30 mph range. [15] The XCH-4 (officially, Experimental Craft, Hydrofoil No. 4 ), designed by William P. Carl , exceeded speeds of 65 mph (56 kn; 105 km/h) and was mistaken for a seaplane due to its shape. [ 16 ]
The Pegasus-class hydrofoils were a series of fast attack patrol boats employed by the United States Navy. They were in service from 1977 until 1993. They were in service from 1977 until 1993. These hydrofoils carried the designation "PHM" for "Patrol Hydrofoil, Missile."
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.
Just like a boat, a seaglider initially floats, then as it picks up speed it foils — gliding over the surface of the water using wing-like structures called hydrofoils, which retract as the ...
When the service ended, the three hydrofoils were acquired by Shun Tak Holdings' Far East Hydrofoil (now TurboJET) for service between Hong Kong and Macau. [3] About two dozen Boeing Jetfoils saw service in Hong Kong–Macau, Japan , South Korea , the English Channel , the Canary Islands , the Korea Strait , Saudi Arabia , and Indonesia .
USS Taurus (PHM-3) was the third ship of her class of hydrofoils operated by the United States Navy. Pegasus class vessels were designed for high speed and mobility, and carried a powerful (for their size) armament.

Flapping wing propulsion devices are hydrofoils that produce propulsion by forcing a foil to move up and down in the water. The forward motion of the foil then generates lift as in other hydrofoils. A common design consists of a large foil at the stern that is used both for propulsion and keeping the passenger above the water, connected to a ...
