The Douglas XC-47C was a floatplane producing by fitting Edo Model 78 floats to a standard C-47. The prototype, with a 1942 serial number and powered by two Pratt & Whitney R-1830-92 Twin Wasp engines, handled well in the air, although could carry less cargo than the standard C-47. The single-step metal floats contained retractable wheels, located at the step, allowing the XC-47C to operate on land, but the tires were prone to fail.

The biggest problem with the XC-47C was that it could only operate on smooth water, greatly limiting its usefulness. Despite this 150 sets of floats were ordered from Edo, and the C-47C saw limited service in New Guinea and Alaska (where smooth water must have been in very short supply).

At Western Airlines in 1970 I flew with one of the test pilots of the float C-47. The only thing I can remember him saying was that EDO must have made a bundle of money as there were 50 floats in crates next to one of the hangers.

Add some motion to that big thing ...

Filmed circa 1942 in beautiful Kodachrome color at the EDO plant in College Point, NY and at Laguardia Airport. EDO manufactured attachable floats that converted conventional aircraft into seaplanes.

Re: why d Sony floats were built....

The USAAF probably thought they'd be useful in Alaska and Canada...where they could operate from smooth lakes and where there was a lot of construction work going on at that stage of the war.

If you put them on a turbine DC-3/C-47 today, you'd probably find a market for it flying cargo in Alaska...now, whether the FAA would allow it....
