Sopwith 1913 Circuit of Britain floatplane

The Sopwith 1913 Circuit of Britain floatplane was a single racing aircraft built by the Sopwith company to compete in the 1913 Daily Mail Circuit of Britain air race, a seaplane contest around the coasts of Britain and Ireland. It was a four-bay tractor biplane with a square-section fuselage, ailerons on both wings and a 100 horsepower Green E.6 engine, and it was the only one of four entrants to start the race. Harry Hawker flew it with Harry Kauper as passenger and, after a restart, covered about two thirds of the 1450 mile course before a landing accident near Dublin ended the attempt. Hawker still received a 1000 pound prize and a silver medal from the Royal Aeronautical Society.
