Pan American Seaplane Tender PANAIR XX-P


PANAIR XX-P, a 1940 build from Julius Petersen for Pan American Airways.

Just completed, another 3D Printing exercise. This is one of a fleet of 36 foot seaplane tenders ordered by Pan American Airways in 1939. The boats were sent to PAA stations around the world, and tended to the big Martin and Boeing seaplanes– the Pan American Clippers. The boats were equipped search lights, towing and rescue gear, but rarely left the harbor except to “sweep” the landing areas for any floating debris.

This boat though, PANAIR XX-P, was stationed at Honolulu, and became a war veteran on December 7, 1941. Her fire fighting gear was put into use in several locations around Pearl Harbor; the photo below shows her (along with the famous tug HOGA) assisting at the West Virginia.

The model is 27 inches long in 1:16 scale, and is almost entirely 3D printed. Even many metal fittings were investment cast from 3D printed wax patterns. Read all about my discovery of these boats, and the construction of the model, at my RC Groups build log:



Hull and cabin were each printed in two parts to fit in the printer.

      Not sure what “32 rc snowball” means… but I’d need the plans of the original boat…
      several hundred dollars for design time… several hundred more for the 3DP hull.
      Sintered nylon would be used, and yes that could be glassed over… probably unnecessary though.

      BTW, your e-mail address is no good.
