PURPOSE:To fully ensure a range of watch work visibility at entry into and departure from a port, by moving a long and narrow travelling platform to selectively laterally both side directions on an upper deck bridge of a ship body and providing both the platform and a watch work box synchronously moved with the platform. CONSTITUTION:A bridge 3, provided as an upper structure on an upper deck 1 of a ship body, is formed with its width smaller than width of the upper deck 1 of the ship body and arranged with alignment of the center of its width to the center of the upper deck 1. A travelling directionally long and narrow platform 4, selectively movable to the direction in a left side or right side, is further provided to the bridge 3. A watch work box 6, synchronously movable in the same direction as of movement of the travelling platform 4, is provided to said travelling platform 4 normally stored in the bridge 3 and protruded from the bridge 3 at watch work. |
