US Navy, Hydrofoil Boats

US Navy, Hydrofoil Boats, vintage 8 x 10 inch glossy silver print photograph credited to the Boeing Company.

A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.
