Abstract A sea-going high-commercial-speed displacement vessel consisting of an upper hull 1, in the form of one or several floor pontoons being equipped with narrow stabilizing floats 12 provided at least at one side of the plane of symmetry with pneumatic chambers 22, the width of which are adjusted by the pressure of a compressed gaseous medium, and which are arranged in the area of bilge 11, as well as at least one midwater hull 2 which comprises light ballast containers 20 and is fastened under the upper hull 1 by brackets 3,4 slidingly attached to the hull 1 and catches 13 and interlocks 14. The midwater hull 2 of the vessel is provided with adjustable stabilizing fins 17, simultaneously serving as deep-water rudders, and also with directional rudders 5 rotated by hydraulic rudder engines 18. The vessel comprises power plant 6 and screw propellers 7, situated at the height approximating the height of the frontal resistance center at the commercial speed, and enclosed within the hull 1 are active rudders 10 for manoeuvring the vessel after lowering the upper hull 1 to the water surface.
A sea-going high speed displacement vessel comprising, in combination, a surface hull of displacement equal to displacement of the vessel, the form of said hull being substantially similar to a rectangular pontoon having several decks; stabilizing elements at the bilge for stabilizing the vessel; at least one midwater hull having full buoyancy in form of streamlined floats with small wetted surface, said midwater hull having light ballast containers and being positioned at variable height under said surface hull; brackets mounted slidingly in said surface hull and having catches for joining said surface hull and said midwater hull after water has been removed from them by means of compressed gas; active rudders positioned in said surface hull, said stabilizing elements in the form of floats having chambers at least at the side of the surface hull''s symmetry plane, the width of said chambers being adjusted by means of compressed gas, at least one midwater hull has adjustable stabilizing fins, said fins being also deepwater rudders; and power plant and screw propellers situated at the height approaching the height of the frontal resistance center at the commercial speed of said vessel, said fins, power plant and propellers being situated for permitting balancing longitudinally the vessel with respect to the resistance forces, said resistance center lying substantially at the level of the propeller shaft axis when said vessel moves forward at said commercial speed, said brackets joining said hulls having directional rudders rotated with said stabilizing elements by means of rudder engines.
