Abstract

(57) [Summary] [Purpose] To carry out tethered storage in small vessels that can prevent the adhesion and reproduction of shells and seaweed without protecting the bottom of the vessel with lead mixed paint. [Structure] A light-blocking sheet 1 having a size covering from the bottom of the ship to the upper part of the waterline, and means for attaching to the hull is provided at the outer edge of the sheet 1. This sheet 1 is made of dark-colored nylon woven fabric, and the reinforcing tape 2 attached to the outer edge is covered with eyelets 3
Is provided and a rope is passed through the eyelet 3 to attach it to a small vessel.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bottom cover for a small vessel that covers the bottom of a small vessel or yacht that is stored in a harbor or a marina in a tethered manner.

[0002]

[Prior art]

 Conventionally, 95% or more of so-called small vessels with a discharge of less than 5 tons have been moored at sea, and about 5% have been stored on land at port facilities. In recent years, floating docks have started to be used for storage on the shore, but it is said that land storage that is completely pulled up from the sea is the most preferable.

[0003]

[Problems to be solved by the device]

 However, land storage is not realistic due to lack of equipment and high cost, and storage of the sill by a floating dock is even more difficult. On the other hand, in the case of moored storage on the sea, shellfish and seaweed adhere to the bottom of the ship and propagate.Therefore, repair work such as scraping and repainting the adhered shellfish and seaweed, or applying paint mixed with lead etc. to the bottom of the shell , It is necessary to prevent the adhesion of seaweed. However, the former has a problem of work load, and the latter has a problem that lead and the like dissolved in the sea pollute the environment.

Therefore, with the aim of easily and safely mooring small boats that are often used for leisure at present, the adhesion of shells and seaweed without the need to protect the ship bottom with paint mixed with lead, etc. As a result, we investigated two issues: prevention of breeding and, as a result, reduction of repair work and elimination of pollution caused by lead-based paint.

[0005]

[Means for Solving the Problems]

 As a result, a light-shielding sheet 1 having a size that covers from the bottom of the ship to the upper part of the waterline, and a bottom cover for a small ship in which a means for attaching to the hull is provided at the outer edge of the seat 1 was considered. The cover may have a size that exceeds the waterline.

It is preferable that the light-shielding sheet 1 is formed of a dark-colored woven cloth, and a means for attaching it to the hull is a cover formed by passing a rope through the eyelet 3 provided in the reinforcing tape 2 portion attached to the outer edge of the sheet. The material of the sheet and the reinforcing tape may be the same or different, but nylon woven cloth is preferable. The eyelet may be integrally formed from the same material as the sheet, or may be made of metal and attached later. Sheet 1 should be black.

[0007]

[Action]

 In the bottom cover for a small boat of the present invention, the woven cloth as the material of the sheet 1 has good water permeability, which prevents invasion of grown shellfish and seaweed but allows seawater to pass through. As a result, when the seat 1 is attached to the bottom of the ship, the seawater caught between the seat 1 and the bottom of the ship is discharged to the outside of the seat 1 and adheres to the bottom of the ship, preventing the growth of shellfish and seaweed from adhering to the bottom of the ship. Furthermore, the dark color of Sheet 1 blocks the sunlight, and even if there are shellfish or seaweed attached to the bottom of the ship, it prevents their growth and prevents the reproduction of shellfish and seaweed.

[0008]

【Example】

 An embodiment of the ship bottom cover of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a leisure motor boat with a cover according to an embodiment attached thereto, and FIGS. 2 to 4 are side views showing a procedure of attaching the cover to the boat.

As shown in FIG. 1, the cover uses a black sheet 1 made of nylon fiber woven cloth, which covers the bow 13 to the stern 15 of the boat 11 and is twice as large as the deck of the ship. At the time of mounting, a reinforcing tape 2 made of nylon fiber woven cloth is attached to the outer edge of the sheet 1 that abuts the upper part of the water line 12, and metal eyelets 3 are attached at appropriate intervals.

To install the cover, first, as shown in FIG. 2, the tip of the seat 1 and the bow 13 are tied together with a rope 17 on the deck. Attach ropes 18 to the two corners of the rear end of the seat 1 and hold the rope 18 while the operator holds the rope 18 and unfold the seat 1 from the front of the bow 13 to the sea. Then, as shown in FIG. 3, while pulling the rope 18 on both sides, the seat 1 is dipped under the bottom of the ship. It is easier for the rope 18 to work than the captain.

An operator pulls up the seat 1 completely dipped under the ship bottom 16 from the stern 15 and ties the ropes 18 to the left and right of the stern 15 and fixes them. In this way, when the seat 1 is fixed with the rope 17 and the rope 18 at the bow 13 and the stern 15, respectively, both sides of the seat 1 are located near the waterline. Here, as shown in FIG. 4, when the ropes are sequentially passed through the eyelets 3 on both sides of the seat 1 and fixed, the cover attachment is completed. This mounting work can be completed in about 20 minutes with a general boat (captain of 8 m) as in the embodiment. Removal of the cover is the reverse procedure, and the required time is 5 minutes.

[0012]

[Effect of device]

 By using the bottom cover for a small ship of the present invention, shellfish and seaweed will not adhere and propagate on the bottom of the ship without the use of paint mixed with lead, etc., so that tethered storage can be performed with peace of mind. As in the past, there is no problem of environmental pollution due to lead, etc., and repair work such as repainting of the ship's bottom is not required, so maintenance costs can be reduced compared to the past.
