Claim:
A combination floating pontoon boat and air-cushion supported hovercraft, comprising: a frame; a plurality of pontoons pivotally and retractably mounted to the frame, the plurality of pontoons having a first position extending downward from the frame and a second position extending substantially laterally outward from said frame; a skirt attached to and extending from the frame, the skirt in a first position being retracted against a bottom of the frame, the skirt in a second position extending downward from the frame and forming an air-receiving pocket beneath the bottom of the frame; a first power system adapted to move the frame through water when the plurality of pontoons are in said first position; a second power system adapted to drive air into the air-receiving pocket when the skirt is in said second position; and a third power system adapted to propel the frame in a longitudinal direction when air is driven into said air-receiving pocket.
