PROBLEM TO BE SOLVED: To provide a pusher/barge unitary hull capable of attaining a substantial energy saving through improvement of a recovering action during a single cruising of the pusher, releasing of a restriction on its speed and improvement of a propulsion performance under a connected state of the pusher and the barge. SOLUTION: This hull has a pusher 10 and a barge 20 removably formed into a unitary device. A connecting cavity 11 is formed at the central part of a hull head of the pusher 10 to make a three-barrel type hull. A connecting protrusion 21 inserted into the connecting cavity 11 and assembled thereto is formed, a hull bottom part of the pusher 10 is formed into a buttock flow type while it is applied as a slant part 12 cut and raised upwardly in a slant manner toward e hull tail side. Both side surfaces are applied as parallel straight line surfaces 2 over an entire range from a part except the hull head of the barge 20 to the pusher 10. The hull tail of the pusher 10 is provided with a single shaft type, double-shaft type or multi-shaft type propulsion device 13. COPYRIGHT: (C)2004,JPO
