<P>PROBLEM TO BE SOLVED: To provide a large-size displacement type ship for eliminating the need for using ballast water during non-load. <P>SOLUTION: The shapes of the stern part bottom and the bow part bottom are each an approximate isosceles triangle approximate to an isosceles triangle which consists of ship-width-direction sides S11, S21 each having a size W almost the same as a maximum ship width and isosceles sides S12, S13; S22, S23 located on the stern side and the bow side of the ship-width-direction sides, respectively. A port side propeller 2L and a plurality of starboard side propellers 2R have both propeller shafts 21 to be driven by an engine and propulsive wings 22 attached thereto. The propulsive wings 22 are located below a non-load waterline. On the stern part, stern part oblique shells 14L, 14R on both port and starboard sides are provided which rise obliquely upward from portions of the isosceles sides S12, S13 on both left and right sides of the stern part bottom to the rear sides, respectively. The propeller shaft 21 of the port side propeller 2L and the propeller shafts 21 of the starboard side propellers 2R extend from the stern part oblique shells to the rear sides, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
