Carolina F Boat
The 1918 Carolina Corp F Boat was a wood-veneer version of Curtiss F with major design changes, for USN evaluation. It was a two-place open cockpit biplane floatplane powered by a 100hp Curtiss OXX-6.
Although it was overweight to the extreme and incapable of flight, several design changes produced one attractive version that finally did fly, although only a distance of about 25′.
Unfortunately, the Navy demanded longer and higher.
Of three USN s/ns assigned; A4344 to 4346, all were cancelled except A4343.
