A powered transportation vehicle uses hydro and aero pressure lift on flat bottom surfaces for providing increased efficiency of operation. An elongate hull has a bottom surface having a large length to width aspect ratio operates in water, with a smaller aspect ratio for a second lifting body operating substantially in air. Trailing edges of the bottom surfaces form a seal with water for creating stagnation areas for the water and air for providing lift to the vehicle having a center of lift of the hull forward the center of gravity of the vehicle. A forward portion of the hull bottom surface is upwardly angled from an aft portion as measured from the center of gravity.
