A hovercraft comprising a hull, whose lower part is laterally surrounded by an air duct for supplying air to form an air cushion, the duct being externally covered by air channeling members, known as skirts, and the hull supporting a propulsion system in its upper part, an air-flow generating system being also mounted to the hull. The hull further comprises a first upper part made of metal or a similarly rigid material, which is connected to a second lower part made of a plastic material, to create at least one zone between the first and second parts, for circulation of the air- cushion generating flow. The second part comprises a flexible plastic skin, which is placed at the bottom of the second lower part, at least one layer of a plastic material, in foam form, being interposed between the flexible plastic skin and the rigid frame. |
