Description
Background and Field of the Invention
The present invention refers to a multiple use water vehicle whose object is a new type of floating vessel that may permit not only its motion under optimal conditions of floatability, but also, owing to its structure, it may permit the rescue of persons from the water, (especially in areas of wave break), to lift goods and structures of all types from liquid media, to transport goods and to practice sports or entertainment activities, etc.
Some types of pneumatic floating vessels are already known such as rubber boats and similar ones which are suitable to render some types of services and activities. These known pneumatic floating vessels raise several problems; among said problems is that they retain water between the pneumatic structures that form its walls and the floor.
Catamarans, whose structure is mounted on sets of floating pontoons are equally known. They also pose the problem of collecting water, which results in their instability (the floatation line varies and is uncontrollable); this fact makes them unsuitable for use in big wave areas such as the sea.
The new water vehicle described-in the present invention has faced and overcome the problems stated above by means of a floating structure that may be rigid (hard) or inflatable ,pneumatic with flexible walls in such a way that it not only has the advantage of not collecting water, but, if there happened to occur a breakage or puncture in one of the pontoons or in the principal float, the structure continues to operate without sinking, thus permitting it to arrive at a safe place to repair the damage.
Another advantage of the invention consists in including a stabilizer which is formed of a watertight compartment that can be fed through an orifice which is plugged from outside, thus permitting to add or to remove ballast (for example liquid), so as to vary the flotation line of the vessel and, consequently, to vary its stability. This makes it suitable to the conditions of the liquid medium wherein it moves (i.e. if the water is very calm the flotation line goes down and it is possible to navigate with larger projection of the vehicle above the water level, whereas in case of surge, the flotation line goes up and it becomes necessary to increase the weight by adding ballast into the stabilizer compartment).
Another advantage of the invention is the possibility of using the vessel for rescuing persons from the water; this can be done by means of lateral belts which permit hoisting the persons on board in a horizontal position relatively easily, taking into consideration that hoisting people from the water is usually a rather difficult operation.
Another purpose of the invention is to permit the use of the principal float as an emergency decompressor chamber, applicable to swimmers who, in the course of a diving practice, have had, for some reason, to rapidly ascend to the surface.
A further application of the vessel is to use it for quick motion with a small part under water (as the boat heels over separating its bow from the water), by means of the use of sliding skis provided on the base of the pontoons, which permit its motion in snow or ice with an eolic drive engine and which also permits varying the water line.
One further possibility is to use the stabilizer compartment as an auxiliary water or fuel deposit to the effect of increasing the autonomy of the vehicle or to permit the transport of liquids plus the additional feature that said compartment may come optionally with a partition wall for counteracting the rolling effect to some extent.
Apart from the above stated, further advantages and purposes of the invention will be disclosed in the course of the specifications.
For the above stated reasons, it is easy to imagine the acceptance of the invention is to have when put into practice, whatever may be its category and destination since, owing to its characteristics, it can be used for economical transport of persons and/or cargos as well as for rescuing operations, sports and entertainment, hoisting or removing goods from the water, etc.

Brief Description of the Preferred Embodiment
In general terms, the captioned water vehicle comprises an elongated floating assembly a) formed by an elongated principal float 1) which is arranged between two lateral pontoons 2), FIGS. 1 to 3. The floating structure a) consisting of a float 1) and pontoons 2), the structures may be made of a rigid material (for example glass fiber and resin), or inflatable pneumatic, structured of reinforced vinyl fabric (PVC) (at least the central float 1) so that it can be used as decompression chamber such as stated below.
More specifically, and such as can be seen in the figures, the pontoons 2) as well as the middle principal float 1) may have the same or similar length but are arranged in such a way that the bow extremity 1') of the float 1) projects longitudinally ahead with respect to the extremities 2') of the pontoons 2) whereas particularly on the opposite side, the float 1) ends in a rigid wall 1") which is arranged between the stern extremities 2") of the pontoons 2). The pontoons 2) are connected by means of a rigid transom wall 3 ) with bent edges 3'), which forms a transom and may include a rudder and also to mount an outboard motor m), etc.
The pontoons 2) are also joined to the middle principal float 1) by means of tighteners, welding seams, or a rigid brace structure g), etc.
The watertight compartment 5) is eccentrically lodged within the principal float 1). The compartment 5 is made of the same material as the hull and the compartment 5 which constitutes the stabilizer of the vehicle and which is reached through a loading orifice 6) as shown in FIG. 3. The compartment 5 may have partition walls that control the rolling effect of the ballast in the compartment 5 may be loaded with liquid 5') as ballast in a varying proportion in order to permit changing the gravity center or the floatation line in accordance with the conditions of navigability determined by the state of the water and, according to what has been explained in the first part of these specifications the compartment 5) can also be used for loading with water or fuel for the vessels achieving more autonomy (FIG. 2).
In the present case, the pilot and other passengers are riding on the principal body 1) that may include a windscreen p) and a steering wheel c); the propelling means m) may be any one that is suitable such as an outboard motor, a turbine, a wind propelling helix, a wing for alternative drive within the water such as a whale tail, etc. (FIGS. 4, 6 and 9). The propelling means m) is affixed to transom 3 at the stern end of the water vehicle, to propel the vehicle forward.
The assembly may also include lateral stirrups for support and gripping means such as the inverted U bar 4) arranged in the bow area (FIGS. 1, 3, 4 and 5) the ends of which are fixed on anchoring bases 13) provided on the pontoons 2); or reins fixed in the front of the float 1).
One of the preferred embodiments is the one shown by FIG. 7, according to which the rear wall 1") of the float 1) is provided with a hatchway 7) that may be closed tightly, as well as the tubing 11) which connects a manometer 10) with the inside of 1) and an entrance orifice in such a way that, in case a diver enters through the hatchway 7) and the latter has been closed, the chamber formed by 1) can be used as decompressor chamber in case of emergency by injecting air by means of valve 9 and conduits 8 and, controlling the pressure with the manometer 10) for the purposes stated in the first part of the specifications.
Similarly, and as has been said in the introduction herein, the vessel may be laterally provided with belts 12) that permit hoisting people from the water in case of accidents such as shown by FIGS. 5 and 6.
Finally, the invention may have an auxiliary hoist structure g) provided with a rigging set 14 and 15 to permit hoisting structures or products from the water (FIG. 8).
FIG. 10 shows an alternative detail of the fuel tank 18) of the vessel which is arranged such as stated, so that it may act as connection between the nucleus lid 1' of the principal float 1 and the transom 3).
Finally, in the embodiment of FIGS. 10 and 11, the pontoons 2) are supplied with wedges on which the skis 17) are fixed. The wedges may be short, long, with or without fins, etc. and having a substantially transversal "U" profile, its borders are supported against the walls of the pontoons 2).
There is no doubt that, in embodying the invention, modifications may be introduced with respect to certain construction and form details, without this implying getting away from the fundamental principles outlined in the following claims:
