The Humphreys Biplane was the first serious attempt to build a flying boat in the United Kingdom. Also known as the Wivenhoe Flyer it was designed by dentist Jack Humphreys; it failed to fly.
Design and development
With the help of Forrestt's boatyard, construction by Humphreys of the biplane started in 1908 near Wivenhoe on the River Colne, Essex.[1] With a span of 45 feet it was a sesquiplane biplane with a single-seat hull.[1] The biplane had a Шаблон:Convert JAP V8 air-cooled engine which drove two counter-rotating propellers.[1]
The biplane was launched on 3 April 1909 but it turned turtle and sank due to an accident.[1] Recovered and tested again, The Times reported in April 1909 that a further trial was abandoned when the gearing between the engine and the propellers failed.[2] In May 1909 it did manage to skim the water at speed of 12 knots but failed to overcome the drag in the design and failed to fly.[1]
