Rig for a sailing boat has a split mast with its top third/mast top swung leeward by a ball-and-socket joint in an increasing wind

摘要

A split mast has a flexible mast top (1) to swing leeward in an increasing wind. Torque in a hinged joint is transferred via a chain (6) and gearwheels (4,5) onto a lower mast third, where a flexible swiveling ballast weight (3) on the main mast swings windward near a ship's point of gravity and consequently prevents an injury.
