Abstract

1447. Smith, T. O. Jan. 21. Hydroplane vessels.-The resistance to propulsion of ships and boats is reduced by forming the vessel's bottom and sides from the waterline, or from a point just above the water-line, with a series of inclined planes a<1>, having steps a<2> at their after ends substantially at right-angles to the planes, and extending entirely under the bottom of the vessel. By this construction, air is induced to flow down the angles of the steps and over the surface of the vessel, thus decreasing friction. The forward end of each inclined plane is fastened between the longitudinal stringer and the frame, and the after end is fastened to the outer surface of the frames, or the edges of the plates forming the inclined planes may be flanged and united to form the steps a<2>. The inclines may succeed one another along the whole of the vessel or only a part of it from the bow towards the stem.
