The boom is rotationally supported in a lower journal fixedly engaged medially on the vessel at the center line. The luffspar is joined pivotally with a forward end of the boom and, when rigged for sailing is positioned below and in parallel with the mast. The luffspar is rotationally supported in an upper journal wherein the upper journal, upper end of the mast, and upper ends of the pair of lateral struts are all engaged in a common fixture held in place by the mast and the lateral struts. The upper and lower journals are arranged on a common journal center line. The lower ends of the lateral struts are engaged with the vessel at the port and starboard gunnels. The sail is engaged along a luff edge with the luffspar and along a toe edge with the boom. | |
