  Hydroplane \Hy"dro*plane\, n. [Pref. hydro-, 1 + plane.]
     1. 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 a["e]roplane.
        [Webster 1913 Suppl.]


  
     2. A projecting plane or fin on a hydroplane[3] to lift the
        moving boat on top of the water; also, a gliding boat.
        [Webster 1913 Suppl.]
  
     3. 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}.
        [Webster 1913 Suppl. +PJC]

From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Hydroplane \Hy"dro*plane\, v. i.
     1. Of a boat, to move through water while supported by
        hydroplanes[3] (see {hydroplane[3]}, above).
        [Webster 1913 Suppl.]
  
     2. 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.
        [PJC]
