The Aeromarine HS of 1921 was an Aeromarine conversion of surplus Curtiss HS-2L open cockpit flying boat, using the wings and engine structure with an Aeromarine hull. Possibly only one was built.
Lady Baltimore II pictured here was the short-lived Easter Airways’ plane, displaying part of a commercial “FOR NEURALGIA” message on the underside of its top wing… an additional source of revenue.
The Aeromarine aluminum hulled EO was built in 1924 and first flown in that June, with a shoulder mounted 80 hp Anzani radial engine. Developed from the Aeromarine AMC, the EO was a sesquiplane, the wings were braced by V-struts.
The EO is an open cockpit aluminum-hulled biplane seaplane with a single tractor engine center mounted in a nacelle on the top wing which also housed the fuel tank and oil tank. The upper wing is staggered well forward of the lower wing. The wings are constructed with spruce I-beam spars and ribs with aircraft fabric covering. The hull is built with four watertight compartments. The tip floats are all-aluminum. A cross-through tube accepted a wheel assembly for ground movement.
The Aeromarine EO was designed as an updated replacement to the Aeromarine Model 44 for the customer Earl Dodge Osborn. Osborn was a former accountant for Aeromarine, assistant editor of Aviation magazine and future founder of Edo Aircraft Corporation. The aluminum hull was scaled down from the Aeromarine AMC design, offering advantages in durability, weight and the inability to become waterlogged.
One EO is known to have been completed in 1924, re-engined with a 90 hp Kinner K-5 in 1929 and was destroyed in a crash at Cape May NJ on 12/15/31.
The first flight tests were performed by Osborn in June 1924. The EO was used for demonstration flights for the EDO company. It then transferred ownership several times with a planned flight to Peurto Rico. It was listed as “Washed Out” at Cape May, New Jersey and its registration was cancelled on 21 January 1932.
A reported second or modification to a larger fin, and increased dihedral may have become the Edo Model B.

Similar in configuration to the Curtiss HS series, the AMC (Aeromarine Metal Commercial) was an effort to introduce a civil flying boat of conventional two-bay biplane design that possessed a more modern airframe, most notably an all-duraluminium hull and a dural-framed empennage.
The 1923 AMC was built with spruce I-beam spars and ribs, dural-framed empennage; fabric-covered wings and tail; all-duraluminum hull. The AMC was designed to replace the 75s of Aeromarine Airways and first flew on 1 June 1923.
The AMC flew for the first time in June 1923 and soon afterwards commenced a trial route between New York and San Juan, Puerto Rico, however, Aeromarine and its airline subsidary ceased operations in late 1923, and no more AMCs were completed.
The Morro Castle II can be recognized by its shorter lower wings.
While not a commercial success, the AMC did establish a new standard for flying boats with more durable metal hulls.
Long before Photoshop, this bit of “creative enhancing” asks more than it tells. It could be a short-wing version of AMC, dubbed Morro Castle II, but its placement in an Egyptian setting is a mystery—perhaps for an ad with a relevant headline. The plane appears to be pasted on the background—a small seam below the rudder hinge is visible. If it is supposed to be landing, it is doomed. The prop is stopped and the pilot sits on the coaming away from the controls, which are set for a severe left hand dive into the Nile.

The Aeromarine 85 Ambassador of 1920 was the model 80 with increased gross weight. A flying-boat converted from HS-2L, with seating for four to six passengers
Fifteen examples have been identified altogether, including the Ambassador, the Biltmore, the McAlpin, the Florida, the Vanderbilt and the Morro Castle.
In 1921 Aeromarine modified a number of ex-Navy Curtiss HS-2L into six passenger flying boats as the Model 80.
At least one was place in service with Aeromarine Airways and another is known to have operated out of Baltimore during 1921 and 1922 with Easter Airways.

The Aeromarine 75s of 1920 were conversions of surplus USN Curtiss F-5Ls (actually ex-RAF Felixstowe F.5Ls). The conversion involved moving the two-place cockpit back to the trailing edge of the wings and installing passenger accommodations with side windows in the forward half of the hull.
Completed in late 1920, the first two model 75s began operating in 1921 with Aeromarine’s subsidiary, Aeromarine East India Airways, where they commenced scheduled operations between New York City and Havana, Cuba, via Atlantic City, Beaufort, South Carolina, Miami, and Key West, carrying 12 passengers. The two-day air journey took only half the time required by train and boat. In 1922, as more model 75s came into service, the carrier opened a new route across Lake Erie between Detroit and Cleveland and extended southern services to include Nassau and Bimini islands.
In late 1923, after three year of regular flights, Aeromarine ceased operations due to financial difficulties.
Between 1920 and 1921 Aeromarine Plane and Motor Company modified for the needs for its subsidiary company Aeromarine Airways 8 F.5L coming from the surpluses of the US Navy. Arranged for the transport of 10 passengers, these sometimes baptized apparatuses Navy Cruiser they were used as of November 1920 between Key West, Florida, and Havana, Cuba. One of these seaplanes carried out as of the 1 {{er}} November 1920 the first international air postal connection on behalf of the US Post Office). Aeromarine Airways also exploited the seasonal connections Miami – Bimini – Nassau, New York City – Atlantic City, and the line Cleveland – Detroit starting from July 14th, 1922. These apparatuses were baptized Santa Maria / Wolverine, Pinta , Niña , Colombus , Balboa , Ponce of Leon , Buckeye and Mendoza. This last is famous to have flown over New York with 27 people on board in May 1922. The Polar Bear is a Aeromarine 75 especially arranged for a polar forwarding of hunting organized in spring 1923 by Inglis Moore Uppercu, sole distributer of the cars Cadillac with New York and managing director of Aeromarine.
Seven HS-2L were also converted.
Two F-5Ls (Aeromarine Model 75) with accommodation for 12 passengers used on Key West-Havana run until 1923, when air mail subsidies withdrawn.

A 1922 version of the Aeromarine 52 with Aeromarine U-8D pusher engine. (also known as Model 55-L8)
A total of 4 or 5 of the 3 or 4 place 1919 Aeromarine 50 / 52 / 55 Limousine Flying Boat were built.
The models 50, 52, and 55 represented an ultimately unsuccessful attempt to offer civil versions utilising components of the Navy A40 trainer utilising the wings, tailplane, and general hull structure of the model 40F.
The model 50B of 1919, model 52 of 1921, and model 55 of 1922 all featured enclosed cockpits.
