摘要： PROBLEM TO BE SOLVED: To provide structure of a hull capable of reducing waves generated from the hull at the time of navigation and exerting a bad influence upon the circumference. SOLUTION: A cross section of a ship's bottom part 2 on the side of a stern which is a ship's bottom part at a position lower than the water line of a hull 1 and a stern side part rather than a vertical parting line No. 5 of the hull is formed to be rectangular, the ship's bottom part 2 on the side of the stern is formed to be thinner than an upper part of the hull so that width of the hull at a position of the stern becomes (1/4-1/2) × B against hull width B at a position of the vertical parting line No. 5, and height of the ship's bottom part 2 on the side of the stern formed rectangular is made to become higher from a central part of the hull toward the side of the stern.

摘要： PURPOSE:To automatically determine the optimum course in a sea area, by inputting information of changing course and narrow-area course or avoiding-course steering information in a local sea route to an optimum sea route determining section and necessary/unnecessary information of a change in shipping service to a wide-area sea route determining section. CONSTITUTION:The optimum sea route is determined V by storing a shipping service plan (a), recommended sea route (b), and other information in a file 1 and utilizing the information stored in the file 1 by a wide-area sea route setting section II. When information 24 regarding danger or change in sea route does not exists, an automatic steering command is outputted VI. When danger information 2 is inputted after the optimum sea route is determined, the presence/absence of the danger is discriminated and the discriminated results are inputted to a local sea route setting section IV and narrow-area sea route setting section III. Operability for avoiding the danger of a collision and stranding and steering and sea worthiness of the hull state to a rough voyage are determined at the setting section IV and avoidance of a typhoon and a navigation restricted area and an economical sailing speed are set in the setting section III. Thus the optimum sea route is determined and inputted to a steering device 23 through the output section VI. When this constitution is used, sea route determination which has been made by a captain can be determined automatically in the optimum state.

摘要： PURPOSE:To maintain the degree of swelling of the hull near the front of a propeller in a proper size by forming a recessed section at the main hull of a stern section located lower than the top of the propeller wings. CONSTITUTION:A propeller 2 with a propeller shaft 1 is provided in the hull central surface C of the stern and a recessed section 3 is formed on both right and left sides of the main hull of the stern section located lower than the top A of the propeller wings, respectively. The cross-sectional shape of the recessed section 3 is almost symmetrically tapered with regard to an axis S thats intersects with a main hull imaginary line 1c and the angle made by the main hull imaginary line 1c with this symmetical axis S is 70-110 deg.. As a result, the diffusion of an effective stern flow is prevented and a flow that crosses a section and resistance are minimized.

摘要： PURPOSE:To decrease a pressure rise an and around the bow as well as to aim at a reduction in wave-making resistance, by forming such a type as drawing both ship side water lines in a concave part made up at the center of the bows ranging fron the upper part to the bottom of a ship from the bows by degrees as well as forming both outer ship sides into a parallel surface with each other. CONSTITUTION:A concave part 3, which is inclined backward the more the lower in position ranging from an upper deck 2 to a bottom part, is formed while bot inner ship side water lines 5 are tilted so as to come close in proportion as going rearward starting from a front end of the ship side, at least in a lower position of the load line. In addition, both outer ship sides 4 at the bows 1 are formed so as to be paralleled with each other at least in a lower position of the load line. With this constitution, a flow of seawater flowing in the concave part 3 of the bows entirely runs in the bottom of a ship whereby a pressure rise in and around the bow is decreased, thus a reduction inwave-making resistance can be well promoted.

摘要： PROBLEM TO BE SOLVED: To provide a wave restraining device restraining the occurrence of waves giving undesirable effects to the circumference. SOLUTION: The stern part 1a of a hull 1 is provided with a wave restraining board 6 depressing the apexes of waves developed when a ship is underway, the wave restraining board 6 has its base end part held at the stern part 1a of the hull, and is formed out of a stationary side restraining board 11 whose tip end is formed into a saw teeth shape part 11a, and of a movable side restraining board 12 which is slidably supported by the stationary side restraining board 11 in the bow direction, and concurrently has its tip end formed into a saw teeth shape part 12a. The wave restraining device is also provided with a sliding cylinder device 13 which causes the movable side restraining board 12 to be slid with respect to the stationary side restraining board 1 so as to enable the shape of each saw shape part at the tip end part to be adjusted.

摘要： PURPOSE:To improve the safety of ship sailing by displaying an optical image of display data on each ship or fixed target nearby the window part of a bridge where respective other ships and fixed targets can be seen. CONSTITUTION:A data processing means 2 derive display data on the ship speeds and courses of other ships and the closest distance, the most approaching time, etc., to other ships or fixed target. A hologram of patterns and symbols of characters, numbers, arrows, etc., required to display respective display data based on the derived signal is selected by a hologram selecting means 3. Then an optical image forming means 5 irradiates each selected hologram with coherent light and an optical image of display data on other ships or fixed targets is displayed nearby the window part of the bridge where the respective ships and fixed targets can be seen. Therefore, respective other ships and fixed targets and data on the respective ships and fixed targets can be viewed at the same time, so the safety of the ship navigation can be improved.
