A method for manufacturing an improved hull for vessels, containers or equivalents, comprising the following steps: - preparing an elastic or viscoelastic glue through mixing at least two components (23,24), - monitoring and/or controlling of the mixing for determining if a correct desired mixing product has been achieved, - using at least one sheet of cellular plastic or other light weight material, having an inner side and an opposite outer side, - applying a layer of the correct mixture of the glue onto the hull or on the inner side of the at least one sheet, - mounting of the at least one sheet onto the hull, the sheet being equipped with a multiplicity of through -going air evacuation holes which exits on the inner and outer side of the at least one sheet, respectively, - placing a net, a web, a wire or equivalent air permeable material on top of the outer side of the at least one sheet, wherein the net, web, wire or equivalent air permeable material is coated with a bonded release agent, - fixing the at least one sheet towards adjacent sheets, wherein at least one fastening element is arranged over a joint between the sheets, - mounting a vacuum foil onto the outer side of the at least one sheet, for achieving a vacuum between the at least one sheet and the hull when gluing by vacuum suction, - observing visually if the glue exits out of the air evacuation holes or not on the outer side of the sheet, - removing the vacuum foil and the net, the web, the wire or equivalent air permeable material, - enlarging the joints between the sheets and refilling with putty compound or strips of cellular plastic together with a bonding agent, and - shaping/smoothing the surface of the glued on sheets with abrasive tools. - preparing an elastic or viscoelastic glue through mixing at least two components (23,24), - monitoring and/or controlling of the mixing for determining if a correct desired mixing product has been achieved, - using at least one sheet of cellular plastic or other light weight material, having an inner side and an opposite outer side, - applying a layer of the correct mixture of the glue onto the hull or on the inner side of the at least one sheet, - mounting of the at least one sheet onto the hull, the sheet being equipped with a multiplicity of through -going air evacuation holes which exits on the inner and outer side of the at least one sheet, respectively, - placing a net, a web, a wire or equivalent air permeable material on top of the outer side of the at least one sheet, wherein the net, web, wire or equivalent air permeable material is coated with a bonded release agent, - fixing the at least one sheet towards adjacent sheets, wherein at least one fastening element is arranged over a joint between the sheets, - mounting a vacuum foil onto the outer side of the at least one sheet, for achieving a vacuum between the at least one sheet and the hull when gluing by vacuum suction, - observing visually if the glue exits out of the air evacuation holes or not on the outer side of the sheet, - removing the vacuum foil and the net, the web, the wire or equivalent air permeable material, - enlarging the joints between the sheets and refilling with putty compound or strips of cellular plastic together with a bonding agent, and - shaping/smoothing the surface of the glued on sheets with abrasive tools.
