Definitions

  • the present invention relates to a sail unit, in particular to a sail unit of reduced dimensions and weight, which is easy to transport and simple to equip.
  • this consists, in fact, of a board with a sail that is mounted on an articulated mast, which is sustained and controlled by the windsurfer only by means of the boom. Since it is without a rudder or helm, the board is directed both by acting on the inclination of the mast and by exerting a thrust with one's feet, also according to the condition of windsurfing (displacement or planing).
  • the sailboard is not usable simultaneously by two persons.
  • the term “dinghies” is a heterogeneous group of watercraft of relatively small dimensions, without a cabin, which have in common the fact of having a centreboard.
  • dinghies Apart from some watercraft designed for children (Optimist type), dinghies generally require carriers for road transport and launching, given that they can even reach dimensions and displacements that are by no means indifferent (for example, respectively, a little more than 6 m and approximately 160 kg in the case of the Flying Dutchman).
  • the main aim of the present invention is to provide a sail unit that will overcome the drawbacks described above.
  • a purpose of the present invention is to provide a sail unit that is easy to transport.
  • Another purpose of the present invention is to provide a sail unit that can be used simultaneously by two persons.
  • a further purpose of the present invention is to provide a sail unit that will be convenient and comfortable to use, as compared to a sailboard.
  • Yet another purpose of the present invention is to provide a sail unit that will present a good nautical quality.
  • Not the least important purpose of the present invention is to provide a sail unit that is reliable and relatively easy to produce at competitive costs.
  • the sail unit comprises two half-shells that are joined together, which define:
  • the bottom body is moreover provided with a slit for the passage of a mobile centreboard, whilst the transom is provided with means for fixing a helm.
  • the deck surface is provided with a mast step for resting and supporting a mast, as well as with fixing points for the standing rigging of said mast.
  • One of the main advantages of the sail unit according to the invention derives from its constructional simplicity and from its reduced dimensions.
  • the fact that the structure made up of two half-shells in fact makes it possible to obtain, in a relatively simple way, a unit that combines the characteristics of transportability and manoeuvrability typical of sailboards with the nautical characteristics typical of classic sailing boats of the centreboard type.
  • the unit according to the invention is of relatively reduced dimensions and hence easily transportable, it can be used simultaneously by two persons and, as compared to sailboards, affords the possibility of being manoeuvrable even from a sitting position and hence with a relative degree of comfort and convenience.
  • the sail unit 1 in its most general embodiment, comprises a structure made up of two half-shells 10 and 20 illustrated in detail in Figures 1 and 2 .
  • the half-shells 10 and 20 are joined through coupling surfaces (not illustrated) and define the structure of the sail unit 1.
  • Said structure is constituted by a bottom body 30 of the double-hull type, in so far as it comprises a first hull 31 and a second hull 32, joined together by a substantially plane portion 33.
  • the top half-shell 10 defines a cockpit 11 with the stem 12 open and a deck surface 13 raised with respect to said cockpit 11.
  • the deck surface 13 is provided with a mast step 61 for resting and supporting a mast 60 (illustrated hereinafter), as well as fixing points 62, 63 and 64 for the standing rigging of the mast 60.
  • the transom 12 is provided with means 51 for fixing a helm 50, illustrated in greater detail in what follows.
  • the bottom body 30 is provided with a slit 34 for the passage of a centreboard 40.
  • the sail unit 1 has in fact all the features typical of a dinghy of a classic type (centreboard, rigging and equipment, cockpit, and other characteristics that will be presented in what follows) allied to the ease of transport typical of sailboards. Furthermore, the shape of the bottom body, with double hull, bestows upon the unit excellent nautical performance in terms of speed.
  • first and second hulls 31 and 32 are conveniently the same as one another and have particularly effective waterlines.
  • said hulls have a cross section that is asymmetrical with respect to said longitudinal plane, with an outer half-hull 315 and 325 and an inner half-hull 316 and 326, the outer half-hull 315, 325 having a larger convexity than the inner half-hull 316, 326.
  • the substantially plane portion 33 that joins the first hull 31 to the second hull 32 has, in a position corresponding to the forward part of the sail unit 1, a substantially rectilinear edge 331 that joins the top part 317 and 327 of the stem of said first and second hulls 31 and 32.
  • the two half-shells 10 and 20 can be conveniently shaped in such a way that from their union the deck surface 13 will define an internal space that presents at least one opening that gives out onto said cockpit 11.
  • two openings 130 and 131 are present, which given out onto the cockpit 11 and enable accessibility to the internal space, which can be used for stowing equipment or else be kept free as reserve buoyancy.
  • the cockpit 11 has an open stem 12, it is conveniently delimited, for at least a portion thereof, by raised surfaces that define sitting surfaces for the person or persons that use it.
  • the unit according to the invention can be used also by two persons simultaneously.
  • the presence of the sitting surfaces affords the possibility of manoeuvring from a sitting position, thus preventing the need for a tiring position imposed by sailboards.
  • the present invention then combines the peculiarities of the sailboard with those of centreboard watercraft.
  • the equipment of the unit can be of the type traditionally used in dinghies.
  • the equipment is constituted by a mast 60, and the corresponding standing rigging comprises a first backstay 71 and a second backstay 72 (only one of which is illustrated), which are set symmetrically with respect to said mast 60, and a forestay 73.
  • the sail unit 1 moreover has a centreboard 40, which, as illustrated in the examples of the attached Figures 3-5 , conveniently rotates around a pin 410 between a first position 40A, in which it is entirely lifted up within the bottom body 30, and a second position, in which it is extended on the outside of said bottom body 30 in a position of hydrodynamic lift.
  • a centreboard 40 which, as illustrated in the examples of the attached Figures 3-5 , conveniently rotates around a pin 410 between a first position 40A, in which it is entirely lifted up within the bottom body 30, and a second position, in which it is extended on the outside of said bottom body 30 in a position of hydrodynamic lift.
  • the helm 50 fixed to the stem 12, conveniently rocks between a raised position 50A and a working position in which it is immersed.
  • the mast step 61 comprises an articulated joint, for example a universal joint, which enables the mast 60 to assume different inclinations.
  • the mast can be inclined, for example, from the position 60 to the position 60A; in this way, the position of the sail centre and/or of the angle of incidence of the boomsheet with respect to the wind can be varied according to the requirements and the sailing modes.
  • the standing rigging comprises a first curved spar 81 and a second curved spar 82 (only one of which is illustrated) positioned symmetrically with respect to the mast 60.
  • Each of said spars 81 and 82 has both a first end 811 and 821, fixed to the mast 60, and a second end 812 and 822, fixed in the deck.
  • the two spars 81 and 82 are joined together so as to form a single rigid structure for supporting the mast 60, said structure being fixed in the deck, in a position corresponding to the ends 812 and 822, ahead of the mast, in a position corresponding to the point where the two spars 81 and 82 meet.
  • This equipment of an innovative type constitutes a considerable advantage as compared to traditional equipment constituted by shrouds and stays, both on account of the ease with which it can be fitted and on account of the possibility that is afforded of adjusting the position and inclination of the mast.
  • the point of fixing of the standing rigging in the deck can be varied easily, for example by sliding the end of the spar 82 from point 822 to point 822A.
  • the mast will come to occupy the position 60A, with consequent variation of the sail centre, and will be sustained by the supporting structure comprising the spar 82 that will be in the position 82A.
  • the mast step 61 comprises a rail, which enables longitudinal movement of the foot of the mast.
  • the foot of the mast from the position 61 (typical, for example, when sailing close to the wind) to the position 61B (typical, for example, when sailing close off the wind) by varying at the same time the position of the boomsheet (from 90 to 90B) and hence maximizing the efficiency of the unit 1 at all sailing modes.
  • the sail unit 1 affords the possibility of reefing the boomsheet, for example reducing it to approximately the surface 90C.
  • the technical solutions adopted for the sail unit according to the invention enable the pre-set tasks and purposes to be achieved fully.
  • the sail unit according to the invention presents certain advantages typical of sailboards, such as ease of transport, for example on the roof of an automobile, hence not requiring carriers for road transport or for launching, as is typically the case for centreboard sailing boats.
  • the sail unit according to the invention maintains certain characteristics and peculiarities of centreboard boats, such as nautical performance, corresponding convenience of use, possibility of use also by two persons simultaneously, features that are, instead, not found in sailboards.
  • the materials used may be any whatsoever according to the requirements and the state of the art.
