Abstract: A combination floating pontoon boat and air-cushion supported hovercraft having a frame and a plurality of pontoons pivotally and retractably mounted to the frame for pontoon boat mode, and a second position extending laterally outward from the frame in hovercraft mode. A skirt is attached to and extends from the frame, the skirt on a first position being retracted against the bottom of the frame. In a second position, the skirt extends downward from the frame and forms an air-receiving pocket beneath the frame for hovercraft operation. A first power system moves the frame through water when the pontoons are in their first position. A second power system drives air into the air-receiving pocket when the skirt is in the second or hovercraft position, and a third power system propels the frame in a longitudinal direction when air is driven into the air-receiving pocket.
