The Seal was designed to operate from either shore stations or warships, including the ability to land and take off from aircraft carriers.
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.
