[1] It kept the same general arrangement, a parasol winged machine with a centrally mounted push-pull pair of engines and sponsons for stability on the water.

The Latécoère 23 carried full span ailerons in three sections per wing, fitted with trim tabs.

[1] The fuselage of the Latécoère 23 was 1.30 m (2 ft) shorter than that of its predecessor and the major hydrodynamic alteration was the inclusion of two steps rather than one.

The broad sponsons of airfoil section and almost rectangular plan were also mostly made of wood apart from four duralumin longerons.

The tail unit of the Latécoère 23 was much cleaner than that of its predecessor, with control surfaces merging smoothly into the lines of tailplane and fin.
