Supermarine Sea Urchin
|Manufacturer||Supermarine Aviation Works|
The Supermarine Sea Urchin was an unbuilt British racing biplane flying boat designed by the Supermarine Aviation Works to compete in the 1924 Schneider Trophy. It was to be a single seat biplane, powered by a Rolls-Royce Condor V-12 water-cooled engine buried in the fuselage, driving a pusher propeller mounted on the upper wing via geared shafts. It was abandoned without being built owing to problems with the engine and the transmission required to drive the propeller.
