As a semi-submerged catamaran running at high speed,
No. 897 and Japanese Utility Model Publication No. 62-94998. These semi-submerged catamaran have lower and right struts with their upper ends fixed vertically to the upper hull.
In such a semi-submerged catamaran, in which a hull is formed and a draft line comes to the middle of the strut, an array sonar, a duct, etc. are provided in the lower hull, and a plurality of restoration wings-wings are provided. Was established.
No. 6, there is one disclosed in the public information No. 61-42675 No.
These things hold many restoration wings by a support plate,
Complicates the hull structure. The design concept of the conventional semi-submerged catamaran is based on the idea that the upper hull is supported via struts by the buoyancy of the lower hull. In other words, the design concept of the conventional semi-submerged catamaran includes:
A prominent example of the lack of the idea of the invention, which attempts to solve the instability due to the response of the buoyancy isolated in the water and the ring transfer effect by the structural and buoyant arrangement of the hull, is lacking the idea of the invention. (Strut) mounted vertically. Each of the systems and techniques devised to stabilize the buoyancy of the floating hull (lower hull) in a conventional semi-submerged catamaran has little effect, Insufficient as a deciding factor in the solution. To address the structural instability, a solution was conceived of as a rapidly increasing strut structure on the water surface very close to the waterline. In other words, in the conventional semi-submerged catamaran, the small sway of the hull is finely adjusted by the control mechanism, while the large sway is supported by the buoyancy of the thick upper strut. Made up of Therefore, for large waves and swells, the thick part of the strut hits the body from the front, and huge irregular buoyancy is generated, so efficient horizontal cruising with excellent wave penetration Cannot be expected.

In a conventional semi-submerged catamaran that has been put into practical use, the mounting angle of the strut with respect to the upper hull is vertical, and the buoyancy of the bow and stern on the strut draft line is insufficient. As a result, the buoyancy of the lower hull responds and shifts back and forth, longitudinally, horizontally and horizontally with respect to the swaying and tilting of the hull, so that the hull becomes more unstable and swings greatly. Therefore, there is a problem that it is extremely difficult to effectively and stably cruise by the anti-swing device when the waves, undulations, etc. exceed a certain size. In a conventional semi-submerged catamaran that has been put into practical use, the strut on the water surface that is very close to the waterline of the lower hull is V-shaped when viewed from the front. Since a huge buoyancy having a large line area is formed, there is a problem that various resistances are increased and propulsion efficiency is reduced due to irregular buoyancy generated by waves and swells.

The structure and shape of the lower hull (side body and floating body) of the present invention refer to how to stabilize the buoyancy of the floating body under water and isolated in water. It has been devised based on an ingenuity based on a very simple inventive idea. By devising the structure and shape of the hull, such as the arrangement and combination of buoyancy and the shape of the side fuselage, it is possible to reduce wave-making resistance and eddy-resistance during high-speed cruising and to generate irregular buoyancy due to waves and undulations. By combining the structural buoyancy arrangement, the buoyancy stabilization function of the side trunk is promoted, the buoyancy stabilization is promoted, and the buoyancy is stabilized. By modifying the shape of the side fuselage above the waterline and to the upper hull, it is possible to reduce the occurrence of irregular buoyancy due to waves, improve wave penetration, and act on the tail fin with an inclination angle. The force improves the straightness during high-speed cruising and the steering function. In addition, the buoyancy adjustment (automatic adjustment of ballast water) allows for a more stable and high-speed cruising system. Enables cruising. For small boats, a vertical adjustment system for the upper hull is added.

By attaching the left and right lower hulls, which consist of the side hull and the floating hull, to the upper hull gradually and downwardly, the buoyancy of the lower hull always acts with directivity in the left and right outward direction, for example, mounting When the angle is 30 degrees to the left and right in an expanded shape from the vertical as the base point, the buoyancy continues directionality until the hull tilts to the left or right direction until the inclination reaches the mounting angle of 30 degrees. The responsive ring transfer of buoyancy in the direction is controlled. By increasing the length of the side torso with respect to the floating torso in the front and rear vertical direction, the vertical buoyancy of the side torso is arranged in the front and rear direction of the vertical buoyancy of the floating part, and the floating Stabilize the buoyancy of the trunk before and after and in the vertical direction. For example, in response to the swaying or tilting of the hull, when either the front or the rear of the floating trunk 5 is going to ascend,
Since the floating trunk portion 5 and the side trunk portion 4 are integral with each other, the side trunk portion 4 also rises as much as it rises, and as much as it rises,
The buoyancy due to the side trunk 4 is lost, and a load corresponding to the lost buoyancy becomes gravity with respect to the buoyancy of the floating trunk 5, and the buoyancy of the floating trunk 5 is leveled horizontally. By setting the steady position of the waterline at the longest part of the side trunk, the control function of the buoyancy of the floating trunk in the front-rear and longitudinal response movements is maximized. The function of the hull structure of the side fuselage 4, whose thickness (width) and length has been sharply reduced from the waterline to the top of the water surface, has the role of a support plate for supporting the upper hull.
As a function, the buoyancy of the side trunk above the waterline is reduced to the utmost. Due to the structural reduction of the buoyancy of the side shells, which is extremely close to the waterline and above the water surface, it is possible to minimize the occurrence of irregular buoyancy generated by waves and swells, etc. Wave penetration is improved, and ideal horizontal running becomes possible. The arrow blade effect generated by the fluid acting force acting on the vertical tail unit 7 and the horizontal tail unit 8 formed on the tail unit 6 of the floating body unit 5 promotes the straightness during high speed cruising and suppresses the sway of the hull. In addition to the suppression, when the tail unit and the movable tip unit are operated as rudders, the fluid acting force generated by the inclination angle of the vertical tail unit 7 pushes down the inside of the hull in the turning direction of the hull and pushes up the outside, so that it is added to the hull. In addition, the steering function, such as a sharp turn at high speed, is improved against the centrifugal force in the straight running direction.
