Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for protecting the outer surface of a hull submerged, which can be applied to a small boat such as a pleasure boat or a yacht in, for example, a yacht harbor or a marina.

[0002]

2. Description of the Related Art Conventionally, for example, in order to prevent marine products from adhering to the bottom of a ship, a bottom paint is applied to the bottom of the ship to prevent the marine products from adhering to the bottom of the ship. However, in view of environmental issues, including the challenge of preventing marine pollution, the use of high performance paints has been limited,
In reality, the bottom of the ship has to be cleaned and painted 5 to 6 times a year. In particular, in small boats such as pleasure boats, the adhesion of marine products to the bottom of the ship significantly reduces fuel efficiency.

[0003]

When cleaning and painting the bottom of the ship as described above, the hull is lifted up on land, the ship is mounted on an overhead boat, the bottom of the ship is cleaned, and the cleaned bottom of the ship is repainted. Therefore, there is a problem that a large amount of time and money are spent each time cleaning and painting the bottom of the ship, and in cleaning the bottom of the ship, the bottom of the ship is cleaned by polishing to clean the bottom of the ship. There is a possibility that the wall thickness may decrease, and even after repainting and landing, the pollution of the bottom of the ship will progress steadily, so it is inevitable that the fuel efficiency will surely gradually deteriorate. On the other hand, a floating type overhead device for mounting a hull is also conceivable, but the floating type overhead device is expensive and cannot be said to be highly practical.

Accordingly, the present invention eliminates the need to repeatedly clean and coat the outer surface of the hull submerged as in the prior art, and may reduce the thickness of the outer surface of the hull submerged by cleaning. So that it is lightweight and easy to carry and handle, and can be easily mounted on the hull submerged outer surface within a short time when mounting on the hull submerged outer surface. In order to prevent the deterioration of fuel efficiency by reliably preventing the adhesion of marine products to the outer surface of the submerged hull, it is possible to reliably reduce the maintenance cost by being inexpensive and practical. It is an object of the present invention to provide a cover for protecting the outer surface of a submerged hull.
