Shielded boat hull of composite material with sealed cover or the like and method of fastening the sealing device

A sealing device for electrically sealing a hull in a closure area having a hatch and a removable cover, comprising:

• a first fixing surface on said hull in said closure area, said hull being made of a composite including fibers of an electrically conductive material which are exposed at said first fixing surface;
• A second fixing surface on said cover in said closure area, said cover being made of a composite including fibers of the same kind of electrically conductive material as in said hull and being exposed at said second fixing surface, wherein said closure area includes an overlap closure with stepped outer limitation of the cover and stepped inner limitation of the hull adjacent the hatch for forming flat, annular, adjoining surfaces of steps of the cover and the hull, respectively, said step surfaces including said first and second fixing surfaces;
• a first sealing member laminated to the first fixing surface on said hull by a flexible layered element having fibers of the same kind of electrically conductive material as in said hull;
• a second sealing member laminated to the second fixing surface on said cover by a flexible layered element having fibers of the same kind of electrically conductive material as in said cover;
• and
• wherein a part of said first sealing member is pressed against a part of said second sealing member when the cover is closed.

In a shielded hull having a hatch with a cover, both the hatch and the cover being made of a composite and each having fibers of the same kind of electrically conductive material, a method for fastening a sealing device for electrically sealing the closure of the cover adjacent that part of the hull which surrounds the hatch along first and second fixing surfaces, comprising:

• laminating a first sealing member to said first fixing surface on said hull by means of a fixing agent, said first sealing member having fibers of the same kind of electrically conductive material as in said hull;
• laminating a second sealing member to said second fixing surface on said cover by means of a fixing agent, said second sealing member having fibers of the same kind of electrically conductive material as in said cover;
• and
• pressing away excess fixing agent in the laminated material.
