摘要： PURPOSE:To suppress lead and reaction, applied to an anti-rolling hydrofoil during a surge and at the developing or storage time, to a minimum without specially reinforcing the reinforcing members of a hull frame since the load and reaction are supported by a hydrofoil unit frame, and allow an anti-rolling hydrofoil device to be easily fitted to a hull. CONSTITUTION:A hydrofoil storage recessed part 5 facing the outer face, and hydrofoil developing machine rooms 7 on both sides of the hydrofoil storage recessed part 5 are integrally provided at a hydrofoil unit frame 8 fitted to a hydrofoil fitting part formed on the board side of a hull. An anti-rolling hydrofoil body 3 developable to the outside with the lower part rotatably supported through a horizontal shaft 4 is provided in the hydrofoil storage recessed part 5, and hydrofoil developing cylinder devices 6 for rotating the anti-rolling hydrofoil body 3 through the horizontal shaft 4 is provided in the hydrofoil developing machine rooms 7.

摘要： PURPOSE: To place an unloading board horizontally relative to a wharf without increasing the length of a vehicle ramp board by leading out a wire for turning the ramp board in a stored posture for providing a vehicle travel posture, and adjusting the leading length of the wire, depending on the tidal condition of the sea. CONSTITUTION: For placing an unloading board 16 on a wharf 15, an arm 22 is first swung toward a position aft of a hull 1 under the adjustment of the leading length of an oscillation wire 25 and a turning wire 26. Then, a posture selector sheave 28 is moved toward the forward end of the arm 22. As a result, a vehicle ramp board 10 at a stored posture X turns about a horizontal turning shaft 5, and becomes parallel to the deck 2 of the hull 1. Then, a cylinder rod is made to contract for oscillating the board 16 about the second horizontal shaft 14, and the board 16 is placed on the wharf 15, thereby keeping the board 10 at a vehicle travel posture Y. In this case, when the deck 2 of the hull 1 is located lower than the wharf 15, the wires 25 and 26 are taken up and an oscillation board part 13 is lifted, while being turned about the first horizontal shaft 12, thereby keeping the board 16 horizontal relative to the wharf 15.

摘要： PURPOSE:To enable floating navigation for a short time and restrain rock by providing an auxiliary hydrofoil projecting to the outside near the horizontal surface of a hydrofoil mounting part below a draft line in the front part of a hull in the high speed navigation, while providing a blade mounting angle adjusting device for pivoting the auxiliary hydrofoil about the axis in the direction of the broad side. CONSTITUTION:Auxiliary hydrofoils 4L, 4R are provided to project sideways on the front broad sides of both hulls 1, 2 below the draft line LWL in high speed navigation. The auxiliary hydrofoils 4L, 4R are constituted pivotably about the axis in the direction of the broad side to be pivoted respectively about the axis by mounting angle adjusting devices 11, 11 for adjusting the mounting angle. The mounting angles of the auxiliary hydrofoils 4L, 4R are adjusted according to the navigation speed. Thus, a large lift is obtained even in the low speed navigation to completely float up the hulls 1, 2 so that the navigation can shifted to the high speed one for a short time.

摘要： PURPOSE: To allow the extensive use of a car deck by leading the exhaust pipe from the engine room outboard of the hull and then inboard of the hull, and load vehicles in two stages by providing an intermediate deck on each side of the hull. CONSTITUTION: In a high speed ferry where large vehicles and passenger cars of small height are loaded together, an intermediate deck 4 is provided on each side part of a car deck 3 provided in the hull, where vehicles are loaded in two stages. The engine room 6 in which the main engine 5 is arranged is provided below the car deck 3. An exhaust pipe 7 from the main engine 5 is passed through a space 9 below a ramp 8 to the intermediate deck 4, and led outboard of the hull 2, and again led inboard of the hull 2 at the upper part of the hull 2. The exhaust pipe 7 projected outside of the hull 2 is covered by a covering body 11 whose forward and aft parts are inclined to reduce the air resistance during the navigation.

摘要： PURPOSE:To eliminate injuries of projected hydrofoils at mooring and reduce pitching and rolling, by providing all wave type hydrofoils on the positions of specified rate of hull length from the stern end part as a front wing and a rear wing, supporting them with the struts of the ship's bottom, and providing auxiliary wings on the right and left ends of the respective hydrofoils. CONSTITUTION:Rear wing fitting frames 3 are fitted to the positions of under 5% of hull length from the stern end part on the bottom parts of keels of a pair of leg parts 2 in the bow and stern direction on the ship's bottom, and an all wave type hydrofoil 7 and auxiliary wings 8 which are provided on both end and respectively independently driven, are provided thereon. The center part of the hydrofoil 7 is supported with the strut 11 of the ship's bottom. Front wing fitting frames 21 are fitted on about 60-70% of the hull length in front of the stern end part, an all wave type hydrofoil 22 is supported with a strut 23 thereon, and auxiliary wings 24 are fitted on both ends of it. By the positions of front and rear wings, weight distribution of the hull 1 is improved, and by fixing the hydrofoils 7, 22 between the leg parts so as not to project from the keels, resistance of the hull is reduced and mooring is easily performed.

摘要： PURPOSE:To provide a tunnel stern ship with sufficient motive forces whether the ship moves ahead or astern by attaching a flap means to the aft end of the tunnel stern ship at the rear of a pusher propeller in such a manner that the means freely rolls in the vertical direction, and submerging the other end portion of the ship, and enabling the lower portion of the aft end to be enclosed. CONSTITUTION:In a tunnel stern ship, an aft flap 16 serving as a stern power increasing device is attached at its upper end by hinge 13 to an aft transom 18 at the rear of a pusher propeller 19 in such a manner as to freely roll in the vertical direction. The aft flap 16 includes an upper plate 11 slightly narrower than the ship width and triangular side plates 12 secured to both of its hull cross end portions and integrated with the upper plate 11, and has warp-proof materials 14, 15 provided at appropriate portions. The aft flap 16 is kept rolling downward until the side plates 12 are pressed against an aft end 17 by water flowing into the pusher propeller 19 when the ship moves astern, and thereby air is prevented from flowing into the pusher propeller 19 and the pusher propeller 19 is surely submerged so as to provide sufficient astern power.

摘要： PURPOSE:To easily secure the straightness of a floating bridge, as for a power boat which holds the floating bridge laid on a river, etc. CONSTITUTION:A pressing force detecting device 10 is installed at the top edge of a power boat 2. Since the pressing force detecting device 10 contacts a floating bridge, the pressing force onto the floating bridge can be detected. The relation between the flow speed of the water on the upstream side from the floating bridge and the pressing force is previusly obtained, and the power boat is controlled so that the pressing force corresponds to the flow speed at that time. Accordingly, the floating bridge can be easily kept in a straight line form.
