Abstract

The present invention relates to a ship used as a fishing boat or for passenger transportation. The ship includes: a ship body (10) formed into a streamline shape at least forward, and having positive buoyancy in spite of overturning or breakage by having a lower specific gravity than water; a propeller (20) mounted on the rear side of the ship body (10), and generating thrust by receiving external power; and a steering house (30) built in an upper part of the ship body (10), and controlling propulsion and directions. The ship body (10) includes: a Styrofoam ship body block (11) formed in a set size and shape to form the vessel; and a synthetic resin protection cover (12) attached to the outer surface of the ship body block (11) to be finished and concealed from the outside. Therefore, since the ship body is formed of Styrofoam which has lower specific gravity than water, the ship does not sink due to regular positive buoyancy even when damaged and broken by running into rocks or being overturned, thus minimizing marine pollution and the loss of lives in spite of various marine accidents.

Description

Manufacturing method of small ship and small ship hull with sinking prevention structure}

The present invention relates to a method of manufacturing a small ship and a hull for a ship used for transporting fishing boats, fishing or passengers, and more particularly, the hull is made of styrofoam having a specific gravity lighter than that of water, so as to overturn, as well as aground or collision. The present invention relates to a method of manufacturing a ship and a ship's hull having a sinking prevention structure capable of minimizing marine pollution and human damage even in various marine accidents as it is not sank by positive buoyancy even if it is damaged or broken.

Typically, ships operating on rivers, lakes or seas are built in various forms using materials such as steel, wood, or synthetic resin.

Such a ship can maintain a lighter buoyancy than water by forming a sealed isolation space from the outside inside the hull.

However, if the containment space of the hull is damaged by overturning, stranding or collision due to various marine accidents, it loses buoyancy and sinks rapidly.

The sinking of such a ship has a problem of causing a major catastrophe that causes serious personal injury as well as marine pollution.

In recent years, in order to solve this problem, the isolation space of the hull has been doubled so that even if a part of the hull is damaged by a collision, it has minimal buoyancy.

However, in order to have a dual structure, it is difficult to do the welding because it is necessary to enter the inside of the hull and perform the welding work.

In other words, it is still not possible to fundamentally prevent the sinking of the ship, and even if multiple isolation spaces are formed, there is a problem that when the hull is broken into several pieces due to a serious collision, it will eventually sink.
