A vehicle adapted for airborne flight and waterborne sailing has a fuselage (20) with left and right wings (52, 54) that pivot independently about a respective longitudinal axis from a generally horizontal orientation for flight to a generally vertical orientation to provide wind-driven propulsion for sailing. Further, the wings (52, 54) pivot about a respective second axis (66) that is generally perpendicular to the longitudinal axis to trim the wings (52, 54) for sailing with a given relative wind direction. The wings (52, 54) are mounted by a respective first pivotal joint (56, 58) to the distal ends of respective stub wing/decks (48, 50). The stub wing/decks form a fixed central wing section (46). Water hulls (28) are mounted below the distal ends of the stub wing/decks (48, 50) on vertical pylons (30) to provide stable flotation. Vertical and horizontal stabilizers (40, 60) are mounted on the back ends of the water hulls (28).
