The Aeromarine 50, also called the Limousine Flying Boat, was a luxury seaplane first flown in 1919 and introduced at the Chicago Air Show. The aircraft was a biplane seaplane with a two-pilot open cockpit and enclosed seating for three passengers. The 150hp Hispano Suiza engine was mounted in a pusher configuration.
The 50B of 1919 was a fully enclosed variant (also called Cabin Flying Boat) with 180hp Aeromarine U-8 (>B-8) pusher. An undocumented 50-B-2 Limousine Flying Boat version was also built.
Aeromarine 50-C
Other versions include 50-C, 50-L, and 50-S Limousine Flying Boat also known as Model 50-U8D; all-metal fuselage; 180hp U-8D or Hisso pusher. The model 50-S entered airline service with Aero Limited over the 100 mile route from New York to Atlantic City, New Jersey during 1919. Ostensibly as a passenger carrier, but more likely for the purpose of moving alcoholic beverages following the passage of the Prohibition Act earlier the same year. Those built included N2990 and N7691.
Aeromarine Airways also operated Model 50 flying boats on NYC-Atlantic City service.

The Aeromarine Model 40 was a two-seat floatplane trainer aircraft serving the United States Navy. The aircraft was produced by the Aeromarine Plane and Motor Company of Keyport, New Jersey, and had already made a name for itself by supplying the US Navy with its first carrier-landed aircraft in the Aeromarine Model 39. Whereas the Model 39 could be utilized as a land-based and floatplane aircraft equally (requiring the conversion of the undercarriage to suit each task), the Model 40 was a dedicated flying boat using wing panels and struts of Model 39 on a new flying boat hull.
One or two 40-F may have been tested by the Coast Guard.
Design was conventional for the time, consisting of a contoured boat-like hull fitted to a boxy fuselage mounting a large unequal-span biplane wing configuration. Single pontoons were fitted as outrigger floats, one per each lower wing assembly. The upper and lower wing assemblies were joined by parallel struts making up two bays and fitting appropriate cabling. The student and instructor sat side-by-side just behind the nose and in front of the wing structure in an open-air cockpit. The view was superb from this position with their forward views protected by two simple curved windscreens. The empennage was adorned with a conventional large-area vertical fin and horizontal tailplane system showcasing rounded edges. The powerplant was placed within a strut configuration supporting the upper and lower wing assemblies at mid-span. The engine was situated well above and just behind the pilots, sporting a two-bladed pusher propeller system powered by a single Curtiss OXX-6 series V-8 water-cooled engine producing an output of roughly 100 horsepower (some later Model 40’s were known to fit a Hispano-brand engine in its place). Performance from this pusher arrangement allowed for speeds of up to 71 miles-per-hour with a service ceiling of nearly 1,900 feet. Endurance was listed at about 4.5 hours of flight time.
The Model 40 was designed and built in response to a 1918 Navy Department order for a two-seat seaplane trainer, 200 Model 40’s were initially ordered by the US Navy in 1918.
Very similar in general design to the Curtiss model MF trainer, which it was intended to augment, serialed A5040-5089, fifty 40-Fs were built.
Although the first civil model 40 may have flown in 1918 with a 150 hp Aeromarine U-8 engine, the first documented flight of the Navy model 40F occurred in 1919. When World War I ended, the original Navy order for 200 aircraft was reduced to 50, and all examples were delivered after the armistice. The model 40-F was operated by the US Navy as a trainer. The end of the war in November ultimately signified the end of the production contract, leaving only 50 Model 40 examples produced. Model 40’s still managed to see service in the post-war world solely with the United States Navy. Overall, their operational use proved the airframe too fragile for the constant rigors of water-born operations, to which these results helped in future American flying boat designs. During service, some model 40Fs were reportedly refitted with 150 hp Hispano-Suiza engines to improve performance and payload.
The civil versions (40 and 40B, 140 hp Hispano-Suiza engine; 40C, 150 hp Aeromarrine engine; 40L 130 hp Aeromarine L engine; 40T, 100 hp Curtiss OXX-6 engine; and 40U, 100 hp Aeromarine U-6 engine) were produced in 1919 and sold for around $9000 each. An estimated six civil models were built.
The Aeromarine Model 40 was further developed into the Model 41 to which some existing Model 40’s were converted to this newer design.
The Aeromarine 41 flying boat were conversions of Model 40s mentioned in 1922.

Three years of design work and almost eighteen months construction by Aero Gare of California saw two prototypes constructed, and resulted in flight testing in 1985. A Sea Hawk wing kit, assembled and static load tested, failed in excess of 9.5G loading. Analysis revealed deficiencies in construction technique with changes resulting in a wing capable of withstanding loads in excess of 10G’s without weight penalty. The Sea Hawk was designed from the beginning to utilize composite construction. The Sea Hawk’s unusual biplane appearance has not detracted from its popularity with 150 kits sold in three months from release date. The design has the ability to use many different engines in the 100 to 160hp range.
Tim Good was at AirVenture 2019 and spotted the original prototype Sea Hawk by Garry LeGare hidden behind a garage just off Ripple Ave near Camp Scholler.

Aerocat co-designer Kirk Creelman has been working in the field of Composite Aircraft Design for over a quarter century and the Aerocat marks the culmination of his experience with composite design, form, flow and function. With rivetless seams, a low-drag coefficient and retractable gear, the Aerocat is a four-place aircraft on the kitplane market. The cabin measures 59″ wide across the pilots chairs and 63″ wide across the passenger and baggage area. This aircraft capable of a 180 mph cruise (at 55%) with either twin 135 hp Jabirus or 250 hp turbocharged engine. Range at 55% Cruise is a 1,100 nm. Aerocat Amphibian also offers the multi-platform concept, designed to house a single or twin configuration, and a purchase option which may or may not include floats. All Aerocats come off the production line with a “Floats-Capable” airframe. The design is by co-designers Y.C. Cheng and Kirk Creelman. They devised an airframe that could accommodate a choice of twin or single powerplant options. The power arch configuration allows for a single 210 to 300 HP engine mounted in the middle of the arch or the twin 135 Jabiru Option mounted on each side of the arch. The pusher type propulsion mounted high on the arch also serves to keep the props high and dry for on-water applications.

The prototype MC.94 commercial amphibian flew for the first time in 1935 powered by two 574kW Wright SGR-1820-F air-cooled radial engines, and fitted with retractable wheels which swung forward into streamlined casings in the leading edges of the wings. The two pilots had a fully enclosed cockpit, and up to 12 passengers a main cabin equipped with a toilet to the rear, baggage in an aft compartment and marine gear in a nose compartment. The first five production MC.94 (without the retractable wheels of the prototype) were similarly powered. The only other production aircraft were six similar flying-boats with 596kW Alfa Romeo 126 RC.10 engines. All MC.94 served initially with Ala Littoria.
