Definitions

  • Certain sailing sails of a sporting nature, such as for example windsurfers, have a mast high enough to support a large area sail. This results in difficulties in terms of stability, so that large races, in rough seas, can only be performed by very experienced pilots. In addition, the effort required to put the mast and the sail in place at the start is relatively large.
  • the invention brings important improvements to the points of view which have just been exposed and can be applied to all types of gear using a wing for their propulsion such as windsurfing boards, land yachts, all sailboats (monohulls, multihulls, etc.).
  • a first improvement, constituting the characteristic of the invention, according to claim 1 consists in giving the mast a curvature turned towards the front of the boat, the main sail or main sail being disposed on the mast on the side thereof or reigns the convexity of the curvature.
  • the wind passage corridor between the jib and the mainsail, opens between the luff of the jib and the mast, due to the curvature of the latter.
  • the sheet can be fixed in an adjustable way to the main sail holding system, so that the whole mainsail and the jib follow the rotation of the mast without having to modify the setting of the jib, at the less for small rotations.
  • FIG. 1 we see a small sailboat, like dinghy for example, whose mast 1, instead of being straight, or slightly curved towards the stern as usual, has on the contrary a curvature directed towards the bow.
  • the curvature of circular shape extends over an angle of approximately 30 °. This angle can vary, more or less, depending on the machine equipped and the results sought.
  • the curvature can have its origin at the root of the mast.
  • the mast is provided with a sail 2, attached by the usual means, to the rear of the mast, that is to say on the side thereof where the convex part of the curvature prevails. At its base, the sail is similarly attached as usual on a boom 3.
  • the sail area obtained with the curved mast, is increased. It follows that for the same sail area, it is possible to reduce the height of the mast, which is favorable to stability.
  • the sail is preferably provided with slats 4 to give it a certain stiffness and maintain as much as possible its falling edge 2a on a contour similar to that of the mast.
  • the sail To allow the sail to hold in the risers, it will advantageously be arranged so that part of its surface in the vicinity of its falling edge can spill under the action of a strong wind pressure.
  • the upper batten 4a of flexible material will be fixed to the mast at its end 4b, while the other slats are free relative to the mast, being only linked to the sail. While being flexible, the upper batten 4a will have a cross section sufficient to withstand a wind of normal force and to not bend, thus allowing a discharge of the sail, only in the event of strong risings.
  • Figures 2 and 3 show the curved mast applied to a windsurfing board.
  • the mast is mounted on a ball joint, so that it can turn on itself and take all kinds of inclinations, the control of rotation and tilting being done by a whiskey 5 held by the pilot.
  • the new mast has various advantages which are added to the possibility of reducing the height of the mast and consequently improving stability while reducing the effort to deploy to put the mast back in place. after a fall.
  • This configuration allows better penetration in the wind and accentuates the suction effect when going up close.
  • the invention makes it possible to take advantage of the curvature of the mast to mount the jib in a particular way which reinforces the advantages already exposed and makes it possible to obtain others.
  • FIG. 5 shows this arrangement in the particular case of a rotating mast controlled by a whiskey 5.
  • the luff 9 of the jib 8 is fixed to the mast at its upper end 10 and at its lower end 11, while at the top 12 of the jib (listening point) opposite the luff is attached a sheet 13 which can be fixed in an adjustable manner on the whiskey, for example by means of a cleat.
  • the jib 8 can be deployed opposite the mainsail 2 (FIG. 5) by forming a channel 14 (FIG. 6) which opens in the interval 17 between the curved mast and the luff 9 of the jib.
  • This channel delimited by the main sail and the jib, regularly deflects a large air stream by gluing the air streams, which provides good value for the propulsive thrust.
  • the mainsail and the jib form a set, the orientation of which can be easily adjusted by acting on the whiskey which is fixed to the mast, while for each orientation of the mainsail, the relative orientation of the jib can be modified by acting listening 13.
  • the invention makes it possible to solve the problem of setting up a jib in a rotary mast rigging, such as that of a windsurfing board.
  • the jib which constitutes an additional wing makes it possible to further reduce the height of the mast for an equal or even slightly larger total sail area, therefore to increase stability.
  • the vélique point is brought closer to the axis of rotation of the mast, which reduces the torque to be exerted by the pilot to maintain the whole rigging or to change the orientation.
  • the jib can take a different shape from the usual triangular shape.
  • it could have in its part 15 opposite the luff a rounded shape maintained by a stiffened edge so as to increase the surface of the jib and the covering of the mainsail, thereby promoting the effect of gluing of the air nets .
  • the curved mast can be made of any suitable material: light wood, aluminum, agglomerate of carbon fibers and resin, etc.
  • the amplitude of the curvature of the mast will depend on the materials used and the area desired for the wing.
  • the mast was given a shape in a broken line or by any other addition making it possible to obtain the advance from the top of the mast towards the bow.
