Stabilised rotary sail rigging

Abstract

Stabilized rotating sailing rig for boats formed by a mast, a boom perpendicular to the mast, and one or more sails bent to the common boom and to the mast; rig capable of freely rotating with all its elements, around a vertical axis, with the important and novel characteristic that the top of the mast is stabilized by shrouds and/or stays which tie it to the periphery of the deck or decks of the boat without jeopardizing the rotation of the rig around its vertical axis. This top of the mast stabilization also permits the use of prow fixed sails.

1 . A stabilized rotating sailing rig, especially devised for the propulsion of sailing boats comprising:
 a vertical mast having a first side and a second,   a boom which extends horizontally at both sides of the mast, and   at least one sail bent to the mast and to the common boom,   rig which rotates with all its elements around a vertical axis,   wherein the rig includes sails having a triangular shape, the sails are selected from Marconi or Bermuda type sails, the rig is being supported by a plurality of shrouds and/or stays which stabilize an upper part of the mast by tying the mast to a periphery of a deck or decks of the sailing boat, in such a way that they are outside of a volume of the rig as rotates, thus allowing for even more than 360° rotation of the rig, the shrouds and/or stays are diagonally attached to an exterior part of the deck in order to maximize the size of the common boom.   
     
     
         2 . The stabilized rotating sailing rig, according to  claim 1 , wherein the fixed elements of vessel, (hull or hulls, shrouds and/or stays), and the rotating elements, (common boom, mast, and sails) are connected by a first bearing connecting the top of the mast to the shrouds and/or stays, and a second bearing connecting a lower part of the mast to the hull or hulls of the vessel. 
     
     
         3 . The stabilized rotating sailing rig according to  claim 1 , further including a mast fixed not only to the hull or hulls but also to the shrouds and/or stays, plus an external rotating mast of tubular shape, coaxial with it, rigid or textile, formed by one or more pieces, which rotates with the common boom and with the sails bent to both of them, including bearings between fixed and rotating elements. 
     
     
         4 . The stabilized rotating sailing rig according to  claim 1 , wherein a control of the rotation of the rotating elements of the rig is done from the deck or decks of the boat by a base platform or by a circular rail, backed up by an emergency sheet. 
     
     
         5 . The stabilized rotating sailing rig according to  claim 1 , further including additional rotating shrouds, stays, inner stays, which rotate with the rotating mast, the common boom, the rotating sails, and the rotating platform or rail; as additional stability or rigidity devices. 
     
     
         6 . The stabilized rotating sailing rig according to  claim 1 , wherein a vessel can have one or more rotating rigs, with fixed head sails or even with another type of rig.
