底後方部における各脚部２の外側には水面貫通型の後部
水中翼４がそれぞれ斜めに取り付けられている。A V-shaped submerged front hydrofoil 3 is attached between the legs 2 at the front of the ship's bottom, and a water surface-penetrating rear hydrofoil is attached to the outside of each leg 2 at the rear of the ship's bottom. 4 are each attached diagonally.

側は水没した状態となる。[0011] When the above-mentioned twin-hulled hydrofoil boat is traveling,
The bow side is floated upward from the water surface by the front hydrofoil 3, and the stern side is floated upwards from the water surface so that the hull 1 does not completely rise from the water surface and reaches the water surface a (indicated by imaginary lines) in FIGS. 1 to 3. is lifted by the rear hydrofoil 4 with the bottom submerged in water. In other words, the bow side rises above the water surface, but the stern side remains submerged.

態で航行させることができる。[0012] In this way, the hydrofoil itself is made into a twin-hulled type in order to stabilize it, and when sailing, the hull 1
In other words, the front hydrofoil 3 is kept completely submerged in the water, so at least the front hydrofoil 3 is not hit by waves, and the hull 1 is therefore protected from the water. It can be operated in a stable state.
【００１３】また、前部水中翼３と後部水中翼４とは、

翼３は、後部水中翼４によって発生させられた波の影響
をまともに受けることがない。[0013] Furthermore, the front hydrofoil 3 and the rear hydrofoil 4 are as follows:
Since the front hydrofoils 3 are provided at positions where they do not buffer each other, the front hydrofoils 3 are not seriously affected by waves generated by the rear hydrofoils 4.
【００１４】なお、前部水中翼３および後部水中翼４と
も上反角が付けられているため、船体の横揺れを防ぐこ
とができる。次に、本発明の第２の実施例を図４〜図６
に基づき説明する。[0014] Since both the front hydrofoil 3 and the rear hydrofoil 4 are dihedral, it is possible to prevent the hull from rolling. Next, a second embodiment of the present invention will be described in FIGS. 4 to 6.
The explanation will be based on.

を避けるようにするとともに、横揺れを防止している。In FIGS. 4 to 6, reference numeral 11 denotes the hull of a twin-hull hydrofoil boat having a pair of left and right legs 12 extending in the bow and aft direction from the bottom of the boat. A V-shaped submerged front hydrofoil 13 is attached between both legs 12 at the front of the bottom, and an inverted V-shaped water-penetrating rear hydrofoil is installed between each leg 12 at the rear of the bottom. 14 is attached. That is, the front hydrofoil 13 has an upward dihedral angle, and the rear hydrofoil 14 has a downward dihedral angle, and in this case, the influence of waves caused by both hydrofoils 13 and 14 on each other is also reduced. It also prevents rolling from side to side.

した状態となる。The central bent portion of the rear hydrofoil 14 is supported by a strut 15 hanging down from the hull 11 side. When the twin-hulled hydrofoil boat in the second embodiment runs, the hull 1 floats up to the water surface (indicated by imaginary lines) a shown in FIGS. 4 to 6, but the hull 11 is completely It doesn't rise above the water. That is, the front hydrofoil 13 is submerged below the water surface, and the rear hydrofoil 14 penetrates the water surface.

4 is shaped like an inverted V-shape to penetrate the water surface, but in the third embodiment, as shown in FIGS. Front hydrofoil 2
3 is shaped like an inverted V-shape to penetrate the water surface, and the rear hydrofoil 24 is shaped like a V-shape to be submerged in water, which also has the same effect as the second embodiment.
