Definitions

  • the present invention relates to an anchoring device and a mooring device for boats, and to a mooring system comprising these devices .
  • mooring can be carried out by means of one or more anchors which grip the sea bed.
  • the boat can be moored by tying it to a buoy with cables or chains, or to a sinker, the mooring chain being recovered from the sea bed and secured to a bitt.
  • These systems are relatively difficult to use, and require a rather large number of cables or chains.
  • Italian patent application no. PA99A000008 discloses a mechanical system for anchoring boats to docks, in anchorages, or to tugs.
  • This system comprises a lower section, movable on a rail positioned, for example, on a dock, and an upper section provided with a hydraulic piston.
  • This piston is provided at one end with a bar having a rounded end, on the sides of which a notch is formed, this notch being capable of engaging in a corresponding formation on a structure of a vessel.
  • This system is suitable for large boats and requires a complex control unit for its movement.
  • the object of the present invention is to provide a mooring system for boats which is simple to construct and use, and which is particularly suitable for small and medium-sized vessels, for example recreational boats (yachts) .
  • a mooring device for a boat having the characteristics specified in Claim 1 is proposed.
  • a mooring system for a boat having the characteristics specified in Claim 14 is proposed.
  • the number of lines immersed in the water is significantly reduced according to the invention, by comparison with conventional mooring systems using anchors which grip the sea bed. This is particularly desirable where there is a large number of moored boats, and the lines, which frequently become entangled in propellers, impede mooring manoeuvres .
  • the system according to the invention is remarkably versatile, since it can be installed in any area of a harbour, being suitable for docks and buoys, and can also be used in the vicinity of marine reserves, since it avoids the use of conventional anchors which break up the sea bed.

  • the flexible spacer elements D located on the starboard and port sides of the boat S are used to prevent the boat from approaching the dock P, while also maintaining its alignment with respect to the dock.
  • the operator actuates the transmitter 120 in such a way as to cause the reverse rotation of the actuating elements 63 of the fixed receiving devices, thus releasing the ball elements 52 and allowing the anchoring devices 200 to be extracted manually and recovered.
