IMPROVEMENTS TO ROTARY GEAR FOR SAILING BOATS

摘要

The improvements are characterized in that the connection of the boom to the rest of the boat gear is such that, in the horizontal plane, the boom has to rotate in tandem with the rest of the boat gear but may move from top to bottom in a vertical plane for tensioning the sails; in that the axis can be extended in the width direction when flush over the deck thereby forming a wide and strong base so that the rotation of the whole boat gear can be controlled from said base, not only because all the necessary control mechanisms are provided there but also because all the remainder elements of the boat gear are also forced to rotate with said base; said base may also use rotary stays and shrouds to help support the mast.
