Development of the Caudron C.51
In early 1921, René Caudron completed the design of the Caudron C.51, a new multi-purpose seaplane. This model was conceived as a two-seater, two-bay biplane, a robust configuration for its time, and was powered by a 130 hp Clerget engine.
A Unique Specimen and its Competitive Debut
Only a single example of this seaplane was built, receiving the civil registration number F-AIBL. This aircraft made its first public and competitive appearance at the seaplane races held in Monaco.
The competitions took place from April 13 to April 20, 1921. Piloted by Poirée, the Caudron C.51 covered a 125-kilometer route from Monaco-Cannes-Menton-Monaco in an impressive time of 45 minutes and 27 seconds, securing a prize of 12,000 francs.
