Sea Lion III was entered for the 1923 Schneider Trophy contest at Cowes. Supermarine's test pilot Henry Biard flew the aircraft and managed third place, reaching a speed of 151.16 mph (243.27 km/h). The performance of the Sea Lion III led to Supermarine designing seaplanes instead of flying boats as racers.
