In the patent application for this design, Pruszenski's "Ground-Air-Water Craft" was described as having a box wing with a total wing span in the range of 5 to 10 feet. It had a canard wing at the front to provide pitch control and the canard span was to be no greater than 10 feet. Front and rear wheels could be retracable. The body portion of the fuselage was to be water tight with a hydroplane bottom surface for reduced resistance when the craft was used on the water.
The designer must have visualized flying this machine at unusual attitudes. The rear wheels were to be "beneath said lower main wing at such longitudinal position that they prevent the said lower main wing from contacting the ground when the craft is flying at an extreme upward pitch".
