Description

  The present invention relates to a rescue boat, and more particularly, to a rescue boat suitable for rescue of a victim shed by a natural disaster such as a tsunami or flood.

Japan is one of the most earthquake-prone countries in the world, and many lives have been lost due to the earthquake.
Many of the victims of an earthquake lose their lives due to the earthquake itself, such as the collapse of a building, but many victims lose their lives as a result of the tsunami caused by the earthquake.

The use of rescue boats that can run at high speed on the surface of the water is an effective way to quickly rescue people drifting in the tsunami.
As a conventional rescue boat, for example, a small jet propulsion boat that can travel on water as disclosed in Patent Document 1 below is known. The small jet propulsion boat disclosed in Patent Document 1 is a two- or three-seater boat, and is configured so that a rescue team member can ride and operate on the upper part of the ship body.

However, such a conventional two- or three-seater small jet propulsion boat is suitable for use as a rescue boat for rescue of a marine accident such as a ship accident, but rescues a victim shed by a tsunami. This is not suitable for the following reasons.
A large amount of debris and wood washed away by the tsunami are floating on the water surface after the tsunami. Therefore, even in a small-sized rescue boat with two or three passengers, the hull is large, and there is a risk that floating objects may interfere with the victim.
In addition, combustible materials such as gasoline, toxic materials, and other dangerous materials may be floating on the water surface after the tsunami has occurred. In such cases, a rescue boat on a rescue boat will be used to prevent secondary disasters. Members cannot access castaways.
Furthermore, when a lot of rubble or aquatic plants are floating on the surface of the water, there is a risk that the suspended matter may collide with or get entangled with the screw or rudder of the rescue boat, preventing smooth running.
