A mast is mounted onto a boat for 360°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.

A sailing system comprising: an elongated mast; a mainsail connected to the elongated mast; and means for mounting the mast onto a boat for 360°rotation about its own axis, and for bracing the mast against buckling, said means comprising a masthead at the upper end of said mast, including first journal means engaging the upper end of the mast and allowing the mast to rotate about its own axis relative to the masthead; second journal means mountable onto a boat hull, for engaging the lower end of the mast and allowing the mast to rotate about its own axis relative to the boat hull; a transverse spreader bar extending crosswise of an intermediate portion of said mast; third journal means between said mast and said spreader bar allowing said mast to rotate about its own axis relative to said spreader bar, but maintaining the spreader bar substantially perpendicular to the mast; and shroud means connectible between the masthead and the spreader bar and a boat hull.
