The Supermarine Swan was a 1920s British commercial biplane designed by R.J. Mitchell. A single machine was built by Supermarine at their works at Woolston, Southampton. The world's first twin-engine amphibian aircraft, it was the precursor to the Supermarine Southampton.
The Supermarine Sea Eagle was a British, passenger–carrying, amphibious flying boat. It was designed and built by the Supermarine Aviation Works for its subsidiary, the British Marine Air Navigation Co Ltd, to be used on their cross-channel route between Southampton, the Channel Islands and France.
The Supermarine Commercial Amphibian was a passenger-carrying flying boat. The first aircraft to be designed by Supermarine's Reginald Mitchell, it was built at the company's works at Woolston, Southampton, for an Air Ministry competition that took place during September 1920. Based on the Supermarine Channel, the Amphibian was a biplane flying boat with a single engine, a wooden hull, unequal wingspans and a 350 horsepower (260 kW) Rolls-Royce Eagle engine.

The Supermarine Nanok was a British three-engined biplane flying boat built by Supermarine. Built to meet a Royal Danish Navy requirement, the single prototype was rebuilt as a private air yacht and renamed the Supermarine Solent.
The Hall PH was an American flying boat of the 1930s. It was a twin-engined biplane, developed from the Naval Aircraft Factory PN and could hence trace its lineage back to the Felixstowe flying boats of World War I. The PH was purchased in small numbers by the United States Navy and the United States Coast Guard. It remained in service with the Coast Guard until 1944, being used for anti-submarine and search and rescue duties.
