ABSTRACT:
A sailing craft having a hull with a longitudinal midplane. A primary boom is pivotally mounted on the hull for 360.degree. continuous rotation in either direction about a central vertical axis. The primary boom is connected by lines to a sail boom. At least one angled mast is mounted to the hull and extends upwardly. The mast has a top, the top is disposed approximately above the central vertical axis of the primary boom. A sail is carried by the sail boom and extends upwardly and substantially symmetrically about the central vertical axis. The sail is supported from the top of the at least one mast. The sail boom with the sail thereon has completely free 360.degree. rotation in either direction avoiding contact with the mast. The sail has flake lines swivelably connected to the top of the mast permitting rotation of the sail and flaking of the sail. A tension device maintains tension on the top of the halyard so the sail luff becomes tight when the primary boom rotates either end forward.
