Designed by Felix Knoll and built by Brayton Aeronautical Corp, the Sachem appeared in 1931 as a three place, parasol wing amphibian powered by a 160 hp Menasco B-6 pusher enclosed in a streamlined nacelle. The single step hull was all metal while wings and tail surfaces were fabric covered. Strut mounted sponsons also contained retractable landing gear.
The pontons proved to offer too much resistance in the water and limited speed sufficiently to prevent lift-off from water. Although the craft was equipped to take off and land on the ground, attempts were to wait until water lift-off was achieved.
The Sachem was entered into Govt. competition won by Grumman. Destroyed in New Bedford Ma. 1938 Hurricane
