Abstract:

A vehicle adapted for airborne flight and waterborne sailing has a fuselage () with left and right wings () 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 () pivot about a respective second axis () that is generally perpendicular to the longitudinal axis to trim the wings () for sailing with a given relative wind direction. The wings () are mounted by a respective first pivotal joint () to the distal ends of respective stub wing/decks (). The stub wing/decks form a fixed central wing section (). Water hulls () are mounted below the distal ends of the stub wing/decks () on vertical pylons () to provide stable flotation. Vertical and horizontal stabilizers () are mounted on the back ends of the water hulls ().
