Description
In April 1920, the British Air Ministry announced that it would hold two competitions for commercial aircraft, one for Landplanes and one for Seaplanes. The Supermarine Commercial Amphibian, was designed to compete for the Seaplane prize, and was a single-engined biplane flying boat with a wooden hull and unequal span wings. The engine was mounted between the wings in pusher configuration. The tail had a single vertical fin, and single tailplane mounted halfway up the fin.
The pilot was accommodated in an open cockpit just forward of the wings, and the passengers sat in an enclosed cabin further forward.
The competition was held in September 1920, with the Commercial Seaplane finishing second to the Vickers Viking, winning a prize of £8,000. It was badly damaged in a crash in October 1920, and was not rebuilt. It formed the basis for the Supermarine Seal amphibian of 1921.
