Definitions

  • the present invention relates to a watercraft in accordance with the introduction to the main claim.
  • a watercraft for use as a rescue, patrol or transport means, but not exclusively so.
  • watercrafts for official tasks especially those supplied to the forces of order, the fire service or the civil protection service are extremely costly, both to purchase and to maintain. They usually comprise propulsion means and specific equipment for intervention in their various scheduled tasks.
  • the fleet hence comprises a fire-fighting watercraft equipped for example with fire-fighting pumps, a watercraft equipped with lighting means, a watercraft equipped with rafts and the like for rescuing survivors, a watercraft for transporting materials, etc.
  • the various rescue units are often equipped with a single structure which at any given time is fitted with the means required for the specific rescue operation to be carried out.
  • the actual fitting of the means lengthens the rescue time on the site where they are required.
  • An object of the present invention is therefore to provide a watercraft which represents an improvement on the known art by virtue of low purchase and running costs, while ensuring the flexibility required by the emergency rescue patrol and transport operations.
  • a further object of the invention is to provide a watercraft by which the time required to fit the necessary equipment onto the watercraft is minimized, hence ensuring more rapid intervention on the site where this is to take place.
  • the watercraft 1 comprises a floating hull 2 of U-shape (by way of non-limiting example), well visible in Figure 2.
  • the hull presents a bow part 3 in which a plurality of sitting positions 4 for possible passengers are provided, together with a very spacious loading surface 5.
  • the watercraft is advantageously constructed of composite materials such as glass reinforced plastic, polymers (or metal materials), the whole structure being filled with self-floating foam.
  • a seat 7 to house at least part of a sea scooter 8 is provided at the stern 6 of the hull 2.
  • the sea scooter 8 is substantially of conventional type, comprising its own propulsion and guide means.
  • the seat 7 is of dimensions sufficient to house a large part of the length of the sea scooter and presents a pair of guides 10 associated with it.
  • the guides 10 are fixed to the hull 2 along the seat 7 by screws 11, which make the guides interchangeable. Consequently, the guides 10 associated with the seat 7 can present a different configuration, depending on the type of sea scooter 8 to be connected to the watercraft 1.
  • the guides 10 form retention means between the hull 2 and sea scooter 8, and connect these latter rigidly together.
  • the term "rigidly” signifies that when connected together, the sea scooter 8 and hull 2 present substantially the same roll, pitch and yaw. When connected together, minimal movements can arise between the sea scooter 8 and hull 2 due to the presence of damping means provided within the connection, consisting for example of rubber, polymer or similar profile pieces.
  • the guides 10 present a groove 12 for at least partially housing a perimetral projection 13 on said sea scooter. As known, this projection is covered with rubber to act as a bumper.
  • the seat 7 also presents, fixed to the hull by screws, a support 14 to at least partially support the sea scooter.
  • This support 14 also acts as a flow deviator preventing the water flow generated below the watercraft during movement from violently penetrating into the interstices between the hull 2 and sea scooter 8.
  • the retention means between the hull 2 and sea scooter comprise fixing means 20 which prevent the sea scooter from emerging from the seat 7.
  • fixing means comprise a pair of tie rods 20 connected by first rings 21 to the hull 2 and by second rings 23 to a common hook 22 provided on the sea scooter 8.
  • the tie rods 20 advantageously comprise conventional means 25 for manually adjusting their tension.
  • the fixing means prevent the sea scooter from leaving the seat 7 when the watercraft is moving in any direction. In particular they present a minimal elasticity to compensate the movements of the sea scooter along the longitudinal axis of the watercraft.
  • the sea scooter When the space, the loading capacity and transport capacity of a sea scooter 8 are insufficient, the sea scooter is driven into the seat 7 in the watercraft 1.
  • the rubber perimetral projection 13 on the sea scooter becomes inserted into the groove 12 such that the watercraft 1 and sea scooter 8 engage each other.
  • the tie rods are then fixed to the hook 22 on the sea scooter 8 to rigidify the two units.
  • the sea scooter 8 is started, its propulsion also driving the watercraft.
  • the sea scooter represents a propulsion (including reversing) and guide means for the watercraft 1.
  • the watercraft 1 connected to the sea scooter 8 provides much more space for loading equipment and material, especially for first aid. It also enables several people to be transported, in addition to the two transported by the sea scooter.
  • a first watercraft can for example be fitted out for lighting, provided with electrical generating modules for powering lighting towers also mounted thereon, and with floating lighting buoys, to be used in rescue operations and research. This craft can also be provided with a compressor to maintain self-ballasting lighting buoys under pressure.
  • a second rescue watercraft can be provided with inflatable rafts, for example of London type, to be launched into the water in proximity to those in danger, to protect them and then tow them to safety.
  • a third watercraft can be fitted with fire-fighting means (for example one or more monitors) operated by i.c. engine-driven or electric motor-driven pumps installed on said hull; advantageously the fire-fighting pumps can comprise remote control means, enabling them to be also operated at a distance, by parking the watercraft in proximity to the fire and withdrawing the operators.
  • a fourth watercraft can be provided for transporting materials or passengers, with individual or bench seats.
  • the sea scooter driver can "choose" which watercraft to use, so minimizing intervention times. In effect, it is no longer necessary to fit out the watercraft with the required rescue means, it being sufficient to choose that which most fits the purpose, from a plurality of ready and moored watercrafts, which can also be constructed with different cross-sections or keels, and of different lengths.
  • the watercraft can comprise independent steering and/or propulsion means, so that the sea scooter is at least able to contribute to the propulsion of said watercraft.
  • the guide means 10a (see Figure 4) present a profile 12a shaped to correspond to the outer profile 8a of the sea scooter, so that it can be adapted to any type of commercially available sea scooter by simply changing the guide 10a.
  • the tie rods 20 are replaced by a pair of jaws which, when closed, lock the sea scooter into the seat 7, by at least partially obstructing seat access.
  • the jaws present a projecting shaft with a final portion of elliptical configuration. This portion is insertable into an elliptical seat provided in a block 31 connected to the hull 2.
  • the jaw 20a assumes a locked configuration ( Figure 3) and cannot rotate in the direction of the arrow F. Raising the jaw enables the jaw to rotate (arrow F) and to release the exit for the sea scooter.
  • a pair of inflatable elements are fixed to the hull 2 to the side of the sea scooter 8 on the seat 7.
  • These inflatable elements are pressurized, they press against the sea scooter 8, clinging to the profile of said sea scooter (Figure 4, left) to prevent its exit from said seat 7.
  • These inflatable elements 20b comprise an internal pressure regulator circuit connected to a source of pressurized fluid.
  • Figure 4, right side shows an inflatable element 20b with the sea scooter absent from the seat 7.
  • the hull can be constructed with different keels, for example: cylindrical, flared, sharp edged flat, round, deep V planar, catamaran type and the like.
