Abstract

Abstract An amphibious sail craft with a sail-wing system is disclosed, including a rotatably mounted mast, a rotatable boom pivotally mounted to the mast, and a sail-wing mounted to the boom and rotatable with the boom about horizontal and vertical axes for varying the attitude of the sail-wing among sail positions or wing positions or combinations thereof. Mechanism to turn the mast and to rotate and tilt the boom to thereby control the attitude of the sail-wing includes: sheets to rotate the boom about its axis; a control wheel to selectively pull one or the other of the sheets, or to pull them both to control the rearward tilt of the boom; and a control column and reaction gear to turn the mast away from the movement of the control column.
