In autumn 1913, the Wright Company announced the Wright Model G Aeroboat, a seaplane developed partly through the work of young engineer Grover Loening, whom Orville Wright had hired that summer. Designed in 1913-1914 to compete with the Curtiss Model F, it had a boat-like fuselage and wingtip floats for stability on the water, and Loening, Wright, and Oscar Brindley tested it on this stretch of the Great Miami River. Compared with Curtiss' design, the aircraft had markedly different nose and tail shapes, was slightly larger and lighter, and used a sixty-horsepower six-cylinder engine. The Wright Company promoted it as well suited to sportsmen traveling over water, and Orville reportedly considered it suitable for air mail routes in remote environments. Although the U.S. Navy bought the first Wright G production model, it never added the aircraft to its fleet. The Model G sold poorly overall, and the Wright Company continued to decline after Wilbur Wright's death in 1912; Orville ran the company until 1915, then sold it in 1915 for $500,000 because he was not interested in running it without his brother.
