Definitions

  • the invention relates to a sailing apparatus for towing a driving vehicle,comprising a sailing propulsor composed of a sail stretched by a supporting structure, which is considerably spaced from the driving vehicle.
  • the apparatus is particularly suitable to reach high speeds.
  • German Patent 560512 discloses a towing trimaran provided with a fin (f) to prevent the drift. It does not solve however the problem, since the overturning moment remains the same without any improvement.
  • U.S. Pat N° 3,094,961 relates to a sail supported by three fins, which support also the load (L). The load is not therefore spaced from the sail,and no steering means is provided.
  • U.S. Pat N° 3,631,828, U.S. Pat N° 3,646,902, U.S. Pat N° 3,831,539, and U.S. Pat N° 4,228,750 all disclose steering means formed by driving fins. Since the sails disclosed therein tend to get an aft wind tack, such fins can prevent this tendency only giving rise to a large turbolence in their immersion area so limiting the speed. Further, in consequence, large dangerous reaction forces are rised, which can break the structure or require an oversizing.
  • Analogously French Pat Application N° 81 15443 and U.S. Pat N° 3,981,258 disclose a forced steering of the sail with respect to the boat. These structures are suitable only for an aft wind tack; otherwise the force rised from the forced steering will give rise to a large turbolence around the fin keel and the rudder of the boat.
  • U.S. Pat N° 4,061,099, U.S. Pat N° 4,326,475 and French Pat Application N° 82 06114 disclose asymmetric catamarans which usually achieve good speed performances, but which are dangerous, since a sudden upset is always possible. They further imply a bulky structure.
  • French Pat Application N° 82 00743 discloses a sail which is in a fixed relationship with respect to the boat, which therefore can always steer only along the same single particular tack.
  • a sailing apparatus for towing a driving vehicle comprising:
  • a sailing apparatus for towing a driving vehicle comprises a sailing propulsor composed of a sail 10 stretched by a supporting structure.
  • the particular supporting structure is the main difference among the embodiments of Figures 7 to 13.
  • the sailing propulsor is connected to the towing point 7, placed on the driving vehicle, by the guys 23, 24, 25 and 26; the driving vehicle is formed, for example, by the surfboard 21.
  • the sailing propulsor is supported on the base surface of travelling, i.e. on the surface of the water, by two distinct rotating supporting members formed by floats, which slide on the surface of the water.
  • the first float 19 is connected to the right lower end 13 of the supporting structure
  • the secamd float 20 is connected to the left lower end 12 of the supporting structure.
  • the sailing propulsor is considerably spaced from the surfboard 21 of a distance corresponding to the length of the guys 23, 24, 25 and 26.
  • the sailing propulsor is free to rotate around the towing point 7, on the surfboard 21, always being at a distance corresponding to the length of guys.
  • the towing point 7 supports the feet of the surfer.
  • Each of the four guys 23,24,25 and 26 is connected to an end of the sailing propulsor in a particular connecting point, respectively 29, 30, 28 and 27.
  • the four guys 23, 24, 25 and 26 are connected to the towing point 7 of the surfboard 21 by means of the body of the surfer 22.
  • the relative distance from the towing point 7 of the left side 28, 29 of the propulsor,with respect to the distance from the towing point 7 of the right side 27, 30 is variable;and the relative distance from the towing point 7 of the lower side 27, 28 with respect to the distance from the towing point 7 of the higher side 29, 30 is variable.
  • the floats 19 and .20 are free to rotate by a nearly vertical axis, the true direction of such axis depends on the variability of the rake of the propulsor.
  • the left guys which connect the propulsor to the towing point of the driving vehicle,are connected together, as well as the right guys are connected together.
  • the handgrips 31 and 32 allow to hand easier the guy; the hand 40 of the surfer may let the guy slide or grip into the sleeve 41.
  • the couple of guys 24 and 26 may slide or be gripped directly in the right hand of the surfer, as well as the couple 23 and 25 in the left hand.
  • the left guys 23 and 25 are connected to the left end of a driving rod 35 and the right guys 24 and 26 are connected to the right end of the driving rod 35.
  • the grommet 8 allows to control the sliding and the gripping of the guys 24 and 26,as well as of the guys 23 and 25, so allowing to control the regulation of the relative distance from the towing point 7 of the lower side and of the higher side.
  • the regulation of the relative distance from the. towing point 7 of the left side and of the right side is achieved simply manually turning the driving rod 35 around it vertical axis.
  • each of the guys 23, 24, 25 and 26 comprises a winder arranged on the driving vehicle.

  • Each of the winders 45, 46, 47 and 48 is independently regulable, by the pins 49, 50 and 51, which are supported on the rod 56.
  • Each pin can engage one of the notches 52, 53, 54 and 55 provided on each winder 45, 46, 47 and 48.
  • Each winder can slide along a traverse, which is delimited by the supports 70, 71, 72, 73 and 74, so engaging or releasing the pins 49, 50 and 51.
  • the winder 45 is engaged with the respective pin, while the winders 46, 47, and 48 are released.
  • each of the notches 52, 53, 54 and 55 comprises an undercut 57 to lock the winder in its engaged position.
  • the crank 61 allows to wind or unwind simultaneously all the winders.
  • the crank 61 can be locked by the rod 62.
  • the relative winding of the winders 45 and 46, connected to the left guys 25, 23, with respect to the winders 47, 48, connected to the right guys, allows to regulate the relative distance from the towing point of the left side and of the right side of the propulsor.
  • the relative winding of the winders 46 and 47, connected to the higher guys 23, 24, with respect to the winders 45, 48, connected to the lower guys, allows to regulate the relative distance from the towing point of the lower side and of the higher side of the propulsor.
