PURPOSE:To navigate a ship without capsizing as absorbing waves, by connecting a central part in a longitudinal direction of plural hulls paralleled with each other and a stern part via universal joints of ball joints and the like, while making each hull free of rocking motion independently. CONSTITUTION:Hulls 1 and 2 of the same type are set up in parallel with each other and coupled together via a main joint 3 at a hull parallel central part and a subjoint 4 at a stern part. Ball joints 9 and 10 are installed in a tipe end of each of coupling shafts 5 and 6 attached to the hull by support bodies 7 and 8, constituting the main joint 3. Likewise, the subjoint 4 also constitutes ball joints 18, 19, 12 and 13 between each end part of a joint bar 11 and the hull. According to this method, each of these hulls 1 and 2 rocks independently against waves and the like via these ball joints whereby each hull is able to absorb force made by waves and the like, thus these hulls can be prevented from capsizing.
