Travel Home > Directory > Travel Dictionary > H > Hydrofoil
HYDROFOIL. A boat with wing-like foils mounted on struts below the hull. When the craft increases its speed the hydrofoils develop enough lift for the boat to become foilborne - i.e. to raise the hull up and out of the water. This reduces water resistance and rapidly increase the speed of the craft.
Early hydrofoils used U-shape foils.Hydrofoils of this type are known as surface-piercing since portions of the U-shape hydrofoils will rise above the water surface when foilborne. Modern hydrofoils use T-shape foils which are fully submerged. Fully submerged hydrofoils are less subject to the effects of wave action, and are therefore more stable at sea and are more comfortable for the crew and passengers.
