Borel hydro-monoplane (France)
The twin-float Borel of 1912 was a single-seater and was no more than a seaplane version of the Morane-Borel. One was entered in the round-Britain Hydro-Aeroplane trial. In 1913 Borel produced a two-seat hydro-monoplane. About eight hydromonoplanes (with 59.6 kW; 80 hp Gnome rotary engines) were acquired by the Royal Navy. They remained in use as ship spotters at the beginning of World War I. Others were flown in France and Italy.
