Swivel device

Abstract

The invention relates to a mast and boom coupled thereto by means of a coupling means for a sailing boat, which includes: an elongate structure which bounds a cavity extending in a longitudinal direction; a slotted hole extending on the top side thereof in the longitudinal direction; and a winding member rotatably drivable by drive means and extending in the cavity in the longitudinal direction for winding up and unwinding a sail movable through the slotted hole. The combination of the mast and the boom according to the invention has the special feature that the coupling means includes: a first support coupled to the mast, a second support coupled thereto for rotation round a rotation axis in a plane extending at least more or less perpendicularly of the mast, to which second support, and particularly to the underside thereof, the boom is fixed, and which second support has a continuous slot-like opening which lies in register with the slotted hole in the boom and serves for passage of the foremost zone of the sail facing toward the mast, this such that the edge of the foremost zone of the sail extends in the region of the rotation axis.
