GLENN CURTISS was the first in the U.S. to take off and land on water, January 26, 1911. And within a year, he commercialized this achievement with the Curtiss Model F. In one variant or another, this Curtiss flying boat continued in service for 15 years. Its aviation firsts include aerial military action, autopiloting, marine catapulting, and delivering newspapers to Catalina.

Model F Basics. The Curtiss Model F was a flying boat; that is, unlike a floatplane, the fuselage itself provided its buoyancy. Its biplane layout was typical of the period; its single engine driving a pusher propeller was mounted high above the waterline. A pilot and one passenger sat side-by-side in an open cockpit.

The Model F was powered by a water-cooled Curtiss OXX-3 V-8, a derivative of the OX. The engine produced 100 hp. The Model F’s top speed was perhaps 69 mph.

According to Wikipedia, Model F operators included Brazilian Naval Aviation, Italy’s Regia Marina, New Zealand’s Walsh Brothers Flying School, and the Imperial Russian Navy.

More than 100 Model F variants were produced for military use. Another 16, called the Model 18 and Seagull, were sold for civilian applications.

An Autopilot First. On August 30, 1913, a Model F became the first aircraft to fly under automatic control. Elmer Sperry developed a gyroscopic stabilizer that evolved into today’s autopilot.

A Military First. A sibling of this Sperry-gyro Model F became the first heavier-than-air aircraft to be involved in a U.S. military action: It was launched from the U.S.S. Birmingham on April 25, 1914, in a scouting mission during the U.S. occupation of Veracruz.

Hitherto, balloons had been used for military observation roles, such as during the U.S. Civil War. And Didier Masson’s mission with his Martin pusher was as a freelancer with the Mexican Constitutionalists.

On November 5, 1915, the Sperry-gyro aircraft became the first to be catapulted off a moving ship, the U.S.S. North Carolina.

Civilian Use. Of the 16 Seagulls, 10 of them were sold to Rogers Airlines in Southern California. Emery Rogers was a partner with Syd Chaplin in Chaplin-Air-Line. The airline delivered Los Angeles newspapers to Catalina; Rogers’ Seagulls were in service as late as 1927.

Other early airlines employed Curtiss flying boats. Aeromarine Airways flew H-12 Curtiss craft, larger than Seagulls, on Key West/Havava routes as early as 1920. American Trans-Oceanic Company also flew H-12s on routes that included New York City/Palm Beach/Nassau/Havana. ds

    As of 2019 the only flight simulator version available of this aircraft is the model for Flightgear done by Emmanuel Baranger ( It is a very nicely made model.
