Definitions

  • the present invention has for its object a sail rig for water crafts, particularly for pleasure and race sailing boats, catamarans, sailboards and the like, the said sail rig comprising a movable mast carrying a sail.
  • the invention aims to provide a sail rig which should act upon the water craft so as to relieve its load during its heading, and to facilitate its gliding over the water even with not very strong winds, while reducing the heeling effect and eventually gaining speed with a rather simple and cheap sail which also allows to better catch the wind.
  • reference numeral 1 indicates the hull of a sailing boat provided with a fin keel 2 and a rudder 3.
  • the sail rig of said boat comprises a mast 4 with the respective sail 5 and the boom 6.
  • the mast 4 is articulately connected at an intermediate point along its length to the top end of a mast-supporting structure 7 consisting of a tubular mounting which is firmly fitted onto the structure of hull 1 so as to lie on the craft centre plane, but so as to be inclined astern.
  • the joint 8 for articulating the mast 4 to the mounting 7 is a cylindrical joint, with its axis of rotation extending longitudinally, more particularly extending in a direction parallel to the direction of the axis of boom 6; the mast may be thus caused to assume not only a position contained in a vertical plane passing through the boat center line, but also any desired inclined position about the axis of rotation of the said cylindrical joint 8, in order to attain'the most favourable rake for the best point of sailing of the boat.
  • the angle of this rake will be of 35° to 45° on either side.
  • the boom 6 is an arcuate, fork- or oval-shaped double boom of the so-called wishbone type as used in sailboards and it is articulated at its vertex by means of joint 9, very simply made in form of a simple tie rod or link secured to an eye 20 provided on mast 4.
  • FIG. 5 more clearly shows the configuration of a sail cut according to the preferred shape.
  • This sail has a substantially triangular shape and its depth side, and possibly also it lower side, may be convex rather than straight, and may be provided with battens.
  • the cut of the sail is such that the line along which it is properly set taut corresponds to the straight line extending from the joint 8 to the sheet point 38 on the boat deck. Since the cloth of such a sail would not be sufficiently stretched in the case of the points of sailing ranging from large--hauling to sailing free, a boom 6 is provided and used for maintaining constantly stretched the surface of the sail and for thus increasing the performance of the sail at high speeds.
  • a boom 6 provided with a universal joint 9 arranged on the stern side of the swingable mast 4.
  • the sail In order to make it possible to use this boom, the sail must be of course provided with an opening 22 such as to permit the continuity of the oval-shaped boom.
  • FIGs 1 to 4 there are illustrated also the devices which are provided for achieving the trim of the mast.
  • the said devices comprise two crosstrees or poles 35, one of which is arranged on the left side and the other on the right side of mounting 7.
  • the said running parts are fastened at points 24 and 25 on the mast 4.
  • the running parts 28 are led to the cockpit by means of transmissions 29-30-31.
  • FIG 6 there is shown a modified embodiment of the articulated connection of the swingable mast 4 to the mast-supporting structure 7.
  • the mast-supporting structure 7 presents at its top end a guide bore 39 and a guide pulley 40 for guiding through the said structure 7 a line 41 by means of which the swingable mast 4 is hoisted to its operative position. More particularly, the line 41 is secured to the mast 4 by means of a clove hitch 42 or any other suitable hitch.
  • the clove hitch connection permits to adjust, within certain limits, the position of the point of articulation of the swingable mast 4, along the mast itself.
  • the invention aims to provide a sail rig which should act upon the water craft so as to relieve the load therefrom during its heading, and to facilitate its gliding over the water even with not very strong winds, while reducing the heeling effect and eventually gaining speed with a rather simple and cheap sail, which also allows to better catch the wind.
  • this object is essentially attained by means of a sail rig in which the mast is articulated at an intermediate point thereof to the top end of a mast-supporting structure fitted onto the water craft and extending in the upward direction up to such a height that the mast can be at will caused to assume a substantially vertical position, or it can be inclined to any desired degree.
  • the mast articulated to the mast--supporting structure it is thus possible to cause the mast articulated to the mast--supporting structure to assume at will a standing position, i.e. a vertical, or preferably an astern-cast position with respect to its neutral position; moreover, this mast can be inclined in such a manner that its top end is brought to the weather side, while its bottom end is moved to the lee side.
  • the sail comes to form a sort of slanting wing with respect to the direction of the wind, so that the resultant of the wind force acting upon the sail is substantially directed upwards and can be resolved into the following three components.
  • a first, upwardly directed vertical component which is opposed to the weight of the boat, whereby its gliding over the water is facilitated.
  • a third, longitudinal forward component which is adapted for generating a propulsive force.
  • the sail behaves as if it were hauled on the weather side, or, in other words, the upper section of the mast being moved windward will come to perform the function of the boom in a sail of the spinnaker type.
  • the barycenter of the sail is near to the center line of the boat, whereby the boat sails on a more balanced point.
  • the articulated connection of the tiltable mast to the top end of the mast-supporting structure may consist of a ball or a universal joint, but preferably of a cylindrical joint with its axis of rotation extending in the longitudinal direction of the water craft.
  • the mast-supporting structure may be made in any desired manner, and may consist, for example, of a tripod or ' bipod structure, and may also be formed in the very framing of the craft and of the same material as the craft itself, or else it may consist of a plain, preferably tubular mounting made from light alloy, with or without windbracing.
  • the sail carried by the tiltable mast may be made in any desired manner, and preferably, but not necessarily, it presents an almost triangular shape with the head side on the tiltable mast, with a depth side at the rear, and a lower third side which is substantially parallel to the boat.
  • the sail is brought to the tiltable mast by the ordinary headrope system or even by any other system, such as the head tabling system.
  • the sail rig of the invention may also comprise a boom articulatingly connected to the tiltable mast, the said articulated connection of the boom being preferably located in proximity of the above-disclosed joint for the mast.
  • the said articulated connection of the boom may be a plain hinge joint of a universal joint.
  • it consists of a link fastened of the fore side of the mast.
  • the said boom may be replaced by a shaped batten threaded through a special tabling extending across the sail cloth.
  • the boom sheet acts in a plane containing the axis about which the sail is rotated and consequently it does not produce on the sail cloth any vertical strain which would give rise to a more taut upper portion of the cloth and to a slackening of the lower cloth portion underlying the boom.
  • the sail is thus naintained always in its shape and keeps its initially set tautness independently of the trim of the sail or of the position of the inclined mast.
  • one sheet of the conventional type as used for a conventional common nainsail, with or without a reduction block may be provided, or else two sheets may be provided, one on the starboard side and the other on the port side, just as for the conventional jibs.
  • mast-handling means for moving the swingable mast, mast-handling means nay be provided which consist of conventional running ropes led or not on crosstrees; preferably, however, the nast handling will be performed by acting upon the lower section of the mast with respect to the mast joint, more particularly, by exerting a pulling, or (if the case) a pushing action on the said section of the mast.
  • the mast mounting may be rigged with one or more fixed, outwardly extending symmetrical structures in form of crosstrees or poles which may be fixed in position or may be shifted along the mast mounting.
  • two running parts may be provided, one on each side thereof, with the standing part on the pivotable mast, and led over the boat cockpit so as to determine through their pulling trim (inclination) of the mast to the one or the other side.
  • the said running parts may be of the single pull type, or they may consist of two or more twines so as to reduce the mast handling effort, and the said right and left running parts will be generally connected together so as to form one single part in a closed path.
  • the two outwardly extending structures may be provided on the mast instead of on the mounting.
  • the running parts fastened to the ends of said structures will be led on the mounting, on the one or the other side thereof, whereby such a pulling effort will be exerted as to determine the trim of the mast.
