n. See hydrofoil.

n. A horizontal rudder on a submarine.

verb-intransitive. To drive or ride in a hydroplane.

verb-intransitive. To skim along on the surface of the water.

n. A plane, or any of a number of planes, projecting from the hull of a submarine boat, which by being elevated or depressed cause the boat, when going ahead, to sink or rise, after the manner of an aëroplane.

n. A projecting plane or fin on a hydroplane{3} to lift the moving boat on top of the water; also, a gliding boat.

n. a powered surface boat fitted with planes (hydroplanes{2}) projecting below the hull, designed to lift the boat, when moving rapidly, so that the hull itself is lifted out of the water and the boat is supported by the hydrodynamic forces of the water on the hydroplanes{2}, thus permitting higher speeds; formerly called a gliding boat.

verb-intransitive. Of a boat, to move through water while supported by hydroplanes{3} (see hydroplane{3}, above).

verb-intransitive. to move through a body of water supported by the hydrodynamic forces on a surface, similar in principle to a hydroplane{3}; -- said, e. .g, of automobiles skidding on a shallow patch of water on a road when moving at high speed, thus causing the tires to lose contact with the road surface.

n. A name given by its inventor to the horizontal side-submerging rudder of the Lake type of submarine boat. There are two of these horizontal rudders on each side of the boat manipulated in unison; when they are inclined forward and downward they cause the boat to be submerged bodily instead of having a diving motion.

n. a speedboat that is equipped with winglike structures that lift it so that it skims the water at high speeds

n. an airplane that can land on or take off from water
