The CANT 13 was an amphibious aircraft designed for use on Regia Marina ships in response to a 1925 competition.

The CANT 13 was a conventional amphibious aircraft, a two-seater single-engined biplane amphibian with retractable undercarriage, made entirely of wood.

The hull had an open two-seat side-by-side cockpit with an internal passage that allowed the second member of the crew to reach the two defensive positions, front and rear, both equipped with a machine gun.

Propulsion was supplied by a Lorraine-Dietrich 12Db liquid-cooled V-12 delivering 400 hp (300 kW), driving with a fixed-pitch 2-bladed propeller placed between the two wings above the hull on a tubular steel central supporting .

In 1925 the Ministry of Aeronautics issued a specification for the supply of a new amphibious aircraft to equip naval units of the Regia Marina.
