Abstract: This invention provides a new form of landing gear for a water plane that will minimize the time and power required to accelerate it from the at-rest, displacement-borne phase to the planing phase and takeoff phase of its operation. The landing gear of the invention is of hydrofoil type and separates the buoyant support function from the planing support function and recombines them in a way which causes them to interact, mutually assisting each other in all phases of operation, simultaneously providing a much lighter and stronger structure, having less drag and requiring less power input than devices and combinations heretofore used or proposed. Thus, the plane body is of any suitable water borne hull shape with two wings whose roots are submerged while floating to give transverse stability.
