The Grigorovich M-1 was a flying boat designed by Dmitry Pavlovich Grigorovich and built in Russia in 1913.

Translation from de.Grigorowitsch M-1

The Grigorovich M-1 is a single-engine flying boat of Russian origin. It is essentially similar to the French Donnet-Lévêcque built in 1912. The two-seater aircraft was of mixed construction, with pilots seated side by side. It was powered by a Gnome engine driving a wooden pusher propeller. Support floats at the end of the lower wing stabilized the aircraft in the water. The aircraft was fitted with attachment points for a dolly to bring the aircraft in and out of the water.

Dmitry Grigorovich shortened the nose by about one meter compared to the original, altered the wing profile (Farman F.16), and reduced the hull step of 200mm to 80mm. The aircraft first flew in the autumn of 1913 and fulfilled the expectations through improved handling.
