Chantiers Aéro-Maritimes de la Seine, most usually known as CAMS was a French manufacturer of flying boats, founded in Saint-Ouen in November 1920 by Lawrence Santoni. Initially, the company built Società Idrovolanti Alta Italia (SIAI) designs under licence, but in 1922 it lured Raffaele Conflenti away from SIAI to become head designer, after which it generated its own aircraft designs. CAMS' most noteworthy products were flying boat designs that saw widespread long-term use in the French Navy. CAMS was purchased and absorbed by the French aircraft manufacturing firm Potez in 1933.
