The present invention relates to a method for manufacturing a hull for vessels, containers or equivalents. The method comprises the steps: preparing an elastic or viscoelastic glue through mixing of at least two components; monitoring and/or controlling the mixing for determining if a correct desired mixing product has been achieved; applying a layer of the glue onto the hull (2) or on a first side of a sheet (4) of cellular plastic or other light weight material; mounting the sheet onto the hull, the sheet being equipped with a multiplicity of through-going air evacuation holes (12); placing an air permeable material (6) on top of the other side of the sheet (4), mounting a vacuum foil (8) onto the other side of the sheet; gluing by vacuum suction; observing visually if the glue exits out of the air evacuation holes on the other side of the sheet.
