Supermarine's Sea Otter entered service in 1938 as an air-sea rescue flying boat crewed by three with a 14-metre wingspan. Powered by a single engine and achieving 262.3 km/h, its 12.1-metre fuselage proved practical for rescue operations. The Sea Otter balanced performance with the stability necessary for maritime emergency work.
