A hunting accessory comprises a pair of essentially identical shells which are removably attachable to one another by hinges. At least one shell comprises an unbroken, continuous, waterproof hull useful as the lower portion of a blind in water or marshy areas. A second shell may include a separate openable portion with viewing openings disposed over the hunter's head and upper body when the assembly is used as a blind with a supine hunter concealed therein. The smaller portion is opened when the hunter has a shot at game in the vicinity. The device may also be used for the carriage of hunting equipment, and/or is useful as a closed container for containing and hauling loose materials (leaves, etc.) in an open vehicle. The two shells may be separated from one another, with one of the shells being useful as a game drag or the like.

A method according to claim 9, in which the first density is less than at least one of 300, 400, 500 and 600 kg/m3. 11. A method according to claim 10, in which the first density is greater than at least one of 200, 300, 400 and 500 kg/m3. 12. A method according to claim 9, in which the second density is less than at least one of 600, 700, 800, 900, 1000, 1100 and 1200 kg/m3. 13. A method according to claim 12, in which the second density is greater than at least one of 500, 600, 700, 800, 900, 1000 and 1100 kg/m3. 14. A method according to claim 9, further comprising: arranging reinforcing material over at least part of the buoyancy body before the overmolding so that the reinforcing material embeds in the polyurethane foam of the protective skin during the overmolding. 15. A method according to claim 14, in which the reinforcing material is fastened to the buoyancy body to inhibit movement of the reinforcing material during the overmolding. 16. A method according to claim 14, in which the reinforcing material is distributed unevenly over the buoyancy body, so as to impart a stiffness which varies over the protective skin in a preselected manner. 17. A method according to claim 14, in which the reinforcing material comprises glass fiber. 18. A method according to claim 9, further comprising: abrading at least part of the buoyancy body prior to the overmolding. 19. A method according to claim 9, in which the mold is provided with at least one locating formation that cooperates with the buoyancy body so as to position the buoyancy body in a preselected arrangement with respect to the mold. 20. A submersible vehicle having a hull comprising: a buoyancy body formed from polyurethane foam of a first density; a protective skin formed from polyurethane foam of a second density higher than the first density, wherein the protective skin is overmolded onto the buoyancy body, and at least one of the buoyancy body and protective skin includes an aperture for housing a control and/or power component of the submersible article; and at least one control or power component housed in the aperture. 21. A submersible vehicle according to claim 20, in which the first density is between 100 kg/m3and 600 kg/m3and the second density is between 300 kg/m3and 1200 kg/m3. 22. A submersible vehicle according to claim 20, in which the first density is between 300 kg/m3and 600 kg/m3and the second density is between 700 kg/m3and 1200 kg/m3. 23. A submersible article according to claim 1, wherein the protective skin provides a watertight enclosure for the buoyancy body. 24. A submersible article according to claim 1, wherein the submersible article has a non-circular cross-sectional shape. 25. A submersible article according to claim 1, wherein opposite ends of the submersible article are non-circular.
