Supermarine Seal
The Supermarine Seal was a British amphibian biplane flying boat developed by the Supermarine company. The Seal was further developed into the Supermarine Seagull.
The Seal was designed to operate from either shore stations and warships including the ability to land and take off from aircraft carriers.[1]
Design and development
The Seal was a two-bay biplane with the lower wing mounted on top of the fuselage and the engine mounted below the centre-section of the upper wing. The primary structure of the fusealage was roughly circular in cross-section and was built of planking over a framework of formers and stringers covered with fabric, with the planing surfaces built as separate structures, divided into watertight compartments.[2]
