Abstract
A watercraft (1) comprising a hull (2) and retention means (7, 10, 20, 20 a, 20 b) to connect a sea scooter (8) and said hull (2) together in such a manner that said sea scooter can at least contribute to the propulsion of said watercraft.
Description
- The present invention relates to a watercraft in accordance with the introduction to the main claim. In particular it relates to a watercraft for use as a rescue, patrol or transport means, but not exclusively so.
- In effect, 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 organizations overseeing these services often possess a fleet of specific watercrafts covering every situation and each necessary intervention.
- 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.
- All the available means are seldom used simultaneously in a rescue operation, only the most appropriate means for the required operation being used at any specific time.
- Consequently many of the available means often remain unused.
- Unfortunately, to limit investment relative to watercraft purchase, 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.
- These and other objects are attained by a watercraft in accordance with the technical teachings of the accompanying claims.
- Further characteristics and advantages of the invention will be apparent from the description of a preferred but non-exclusive embodiment of the watercraft, illustrated by way of non-limiting example in the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a watercraft of the present invention connected to a sea scooter acting as its propulsion and guide means; -
FIG. 2 is a perspective view of the watercraft ofFIG. 1 , without the sea scooter present; -
FIG. 3 is a plan view of a detail of an alternative embodiment of the watercraft ofFIG. 1 ; and -
FIG. 4 is a rear view of a detail of an alternative embodiment of the watercraft ofFIG. 1 . - Said figures show a watercraft indicated overall by 1.
- The
watercraft 1 comprises afloating hull 2 of U-shape (by way of non-limiting example), well visible inFIG. 2 . The hull presents abow part 3 in which a plurality ofsitting 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 asea scooter 8 is provided at thestern 6 of thehull 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 ofguides 10 associated with it. Theguides 10 are fixed to thehull 2 along theseat 7 byscrews 11, which make the guides interchangeable. Consequently, theguides 10 associated with theseat 7 can present a different configuration, depending on the type ofsea scooter 8 to be connected to thewatercraft 1. - Essentially, the
guides 10 form retention means between thehull 2 andsea scooter 8, and connect these latter rigidly together. In the present context, the term “rigidly” signifies that when connected together, thesea scooter 8 andhull 2 present substantially the same roll, pitch and yaw. When connected together, minimal movements can arise between thesea scooter 8 andhull 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 agroove 12 for at least partially housing aperimetral 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, asupport 14 to at least partially support the sea scooter. Thissupport 14 also acts as a flow deviator preventing the water flow generated below the watercraft during movement from violently penetrating into the interstices between thehull 2 andsea scooter 8. - The retention means between the
hull 2 and sea scooter comprise fixing means 20 which prevent the sea scooter from emerging from theseat 7. These fixing means comprise a pair oftie rods 20 connected byfirst rings 21 to thehull 2 and bysecond rings 23 to acommon hook 22 provided on thesea scooter 8. Thetie rods 20 advantageously compriseconventional 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 use of the watercraft is apparent from the aforegoing and in particular is as follows.
- When the space, the loading capacity and transport capacity of a
sea scooter 8 are insufficient, the sea scooter is driven into theseat 7 in thewatercraft 1. The rubberperimetral projection 13 on the sea scooter becomes inserted into thegroove 12 such that thewatercraft 1 andsea scooter 8 engage each other. - The tie rods are then fixed to the
hook 22 on thesea scooter 8 to rigidify the two units. - The
sea scooter 8 is started, its propulsion also driving the watercraft. Essentially, the sea scooter represents a propulsion (including reversing) and guide means for thewatercraft 1. Advantageously, thewatercraft 1 connected to thesea 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. - The use of this type of watercraft is particularly advantageous in an emergency rescue or patrol context as several watercraft can be provided pre-equipped with different fittings.
- 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.e. 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.
- During an emergency, 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.
- A watercraft conceived in this manner is susceptible to numerous modifications and variants, all falling within the scope of the inventive concept.
- For example, 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.
- In an alternative embodiment, the guide means 10 a (see
FIG. 4 ) present aprofile 12 a shaped to correspond to theouter profile 8 a of the sea scooter, so that it can be adapted to any type of commercially available sea scooter by simply changing theguide 10 a. - In a further embodiment (
FIG. 3 ), thetie rods 20 are replaced by a pair of jaws which, when closed, lock the sea scooter into theseat 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 ablock 31 connected to thehull 2. When the final portion is inserted into theblock 31 thejaw 20 a assumes a locked configuration (FIG. 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. - In yet a different embodiment, a pair of inflatable elements are fixed to the
hull 2 to the side of thesea scooter 8 on theseat 7. When these inflatable elements are pressurized, they press against thesea scooter 8, clinging to the profile of said sea scooter (FIG. 4 , left) to prevent its exit from saidseat 7. Theseinflatable elements 20 b comprise an internal pressure regulator circuit connected to a source of pressurized fluid.FIG. 4 , right side, shows aninflatable element 20 b with the sea scooter absent from theseat 7. - It should be noted that the hull can be constructed with different keels, for example: cylindrical, flared, sharp edged flat, round, deep V planar, catamaran type and the like.
