A mast is mounted onto a boat for 360 DEG rotation about its longitudinal axis, relative to the sailboat and the rigging for the mast. The rigging braces the mast against buckling and comprises a masthead, a transverse spreader bar and shrouds. A forwardly directed longitudinal channel in the mast receives bolt ropes at the forward edges of two soft fabric panels which together make up the mainsail. Each mainsail panel extends from its bolt rope within the channel out through a narrow slot in the mast. When sailing generally into the wind, each mainsail panel curves partially around its side of the mast and then extends rearwardly from a line of tangency with its side of the mast, generally contiguous the mainsail panel. Each side panel of the mainsail is secured along its lower edge to a separate boom, so that the two booms can be swung apart to move the two sail panels into a "wing-out" position, for use when sailing with the wind.
