Definitions

  • the invention relates to a boat which can be transformed alternately into windsurfing (wind surfing) and catamaran.
  • Windsurfing boards and catamarans are well known as independent boats, each intended for its own specific use and with its own particular structure, so that the user must necessarily have a different boat depending on the job. desired, which involves for him non-indifferent charges for the acquisition, as well as a considerable space to shelter them and difficulties when he wishes to change boat.
  • the invention therefore proposes to produce a boat which can be used, by simple and rapid operations, either for windsurfing (wind surfing) or for a catamaran and by affecting the structure and the functions of one or the other.
  • the invention provides two reciprocally specular shaped shells which can be assembled in a coplanar manner with one another and connected by means whatever it is suitable for this task, so as to make a windsurfing board each of whose hulls represents a longitudinal half, or else arranged parallel to one another and to a certain distance and connected by means of a structure of bracing whatever is interposed so as to achieve a catamaran.
  • the assembly of said two hulls in their correct position to obtain a windsurf board is obtained naked, according to the invention, preferably with interlocking means and, in particular, by making use of interlocking studs with double tail of dovetails.
  • the assembly of said two hulls in their correct position to obtain a catamaran is obtained, still according to the invention, by arranging them in profile after having overturned them by 90 ° on their longitudinal axes relative to the coplanar position of the board. sailing.
  • the dirty cross-bracing and bridging structure of the two hulls in their braced position in the catamaran preferably consists of one or two transverse branches which are also preferably fitted tees on the dovetail hulls and using the same notches provided for the reciprocal assembly of the hulls for windsurfing.
  • an inclined leg in whatever material, is fixed in proximity to the anterior end of each shell, on the outside of these, the legs provide a dynamic upward push.
  • the front part of the hull plunges into the water.
  • the reason must be sought in the fact that the amount of movement of the water hitting the inclined plane (leg) changes in direction.
  • the vector difference between the final momentum and the initial amount of movement of the water indicates the direction of the force with an upward component.
  • the figures show with 1, 2 the hulls constituting the two halves of a wind surfboard and which are specular to each other with respect to the median longitudinal plane of the windsurf board.
  • the two shells 1, 2 are assembled in this case by means of studs 4, 5, 6, 7 double dovetail fitting.
  • Each of said studs 4, 5, 6; 7 is fitted in half in a corresponding notch with a round tail 104, 105, 106, 107 provided in the shell 1, while the other half is fitted in a corresponding notch in dovetail 204, 205, 206 , 207 provided in the other shell 2.
  • the shells 1, 2 are thus clamped and assembled between them.
  • these double dovetail interlocking studs 4, 5, 6, 7 can be provided with an upper clip and a lower clip 8 which are connected to the stud by a long screw. 9 passing through the stud and staples.
  • Double dovetail studs are also used for the application of other operating parts of the windsurfing board 3.
  • the mast 10, the fin 11 and the rear fin 12 of the windsurf board are fixed to as many interlocking studs 4, 5, 6, 7 in double dovetail.
  • the two hulls 1, 2 can also be assembled to make a catamaran 13 as shown in FIG. 4.
  • the two hulls 1 and 2 forming the windsurfing board 3 are for this purpose separated by detaching the interlocking studs 4, 5, 6, 7.
  • Successively the two shells 1, 2 are placed in profile at a certain distance, that is to say by inverting each of them 90 ° about its longitudinal axis, outwards, so as to make it show up its formerly inner surface provided with indentations to tail t dovetail 104, 105, 106, 107 and 204, 205, 206, 207 (fig. 3).
  • the shells 1, 2 are tightened to each other by steel cables 16 provided with tenors 116, each of the ends of the cables being connected to one of the shells 1, 2.
  • a fabric can be stretched, or else a platform 20 can be provided, the latter can be constituted by rigid panels filled with polystyrene and nested one inside the other and in the two transverse branches so as to form a rigid plane on which the user can stand.
  • the catamaran 13 is governed by rudders 21 known per se.
  • the same mast 10 of the windsurfing board is used as the mast 110 of the catamaran 13, a part which can be joined by interlocking.
  • the boom of the sail board 3 can also be used for the tamaran 13.
  • you want to govern the catamaran 13 as a windsurf board you must be able to tilt the mast from the vertical position in another direction whatever either as is done on the windsurf board 3, which requires the presence of a ball joint.
  • its mast 110 is maintained in an upright position for example by means of two high shrouds, two low shrouds and two stays, or else by a single stay in the case where one wish to use a jib.
  • FIG. 6 shows a right tab 123 and a left tab 223 which are fixed on inclined supports 121, 221 by means of rivets R with inclined parts 122, 222 molded in one piece with said supports 121, 221. It has been established by experience that the inclination of the legs 123, 223 is particularly functional if established in 30 °.
  • the supports 121, 221 have grooves 121 ', 221' by means of which they are applied to the pegs 120, 220 of the shells 1, 2 so that the tabs 123, 223 are arranged on the outside of the latter.
