Definitions

• the present invention refers to the field of sailing and/or motor boats, like catamarans and trimarans, with variable width.
• Catamarans are boats, sailing and/or motor boats, well known in the art, consisting of two substantially parallel hulls, connected together through connection means, and living quarters made in a space between and/or on the two hulls and connected to such hulls and/or to such connection means.
• Trimarans are very- similar to catamarans, but they have a main central hull and two substantially parallel smaller side hulls, which carry out a- stabilizing function, the side hulls being connected to the central hull through connection means, in an analogous way to those used in catamarans.
• connection means in an analogous way to those used in catamarans.
• a problem connected to sailing and/or motor boats with variable width consists of exploiting the space intended for the living quarters as best possible, during the sailing phases, whatever the width of the boat with variable width may be at the time, so as to obtain positions suitable for hosting at least one person in charge of steering the boat.
• the variable width of the boat is at its minimum, and therefore in a position such that the hulls are virtually next to each other.
• the space intended for the living quarters between the hulls is practically erased, and therefore it is not possible to foresee a position on the boat suitable for hosting at least one person in charge of steering the boat itself. In this situation of minimum distance between the hulls, the boat is therefore not set up for sailing.
• Patent FR 2,663,899 describes a boat designed to house a means that allows its width to be reduced to that of a single monoblock by means of a special symmetrical device.
• Such living quarters whatever the width of the boat at the time, have a walking surface that always remains above the height of the hulls, making the boat very slim towards the top, and therefore not very suitable for sailing.
• the width of the boat described here is reduced to the minimum, with the two hulls next to each other, excluding the possibility of obtaining a living quarters with a walking surface arranged in the intermediate space between the hulls .
• the problem remains of obtaining a boat that, whatever its width at the time, has a living quarters with a walking surface obtained between the hulls, capable of hosting at least one member of the crew, whilst still maintaining the criteria suitable for sailing.
• Another problem consists in the fact that the walking surface of such living quarters of sailing and/or motor boats with variable width of the prior art is always very narrow, preventing the living quarters from comfortably hosting many people at the same time and preventing more control stations from being obtained inside of it.
• Another further problem connected to sailing and/or motor boats with variable width consists in the difficulty encountered by the crew of such boats in operating so as to be able to vary the width of the boat, during the sailing phases, without running into enormous difficulties due to the particularly unstable sailing trim of the boat at that particular time.
• connection means between the hulls with variable width can, for example, be carried out by means of crossed beams that are generally fixed to the hulls themselves through fixed locking systems, like for example belts, bolts or conical catches.
• fixed locking systems have the drawback of having to be installed/removed each time during the assembly steps of catamarans, like for example the step of preparation for their lowering, and/or disassembly steps, like for example the step for their transportation by road through suitable transportation means, or the step for their harbourage at suitable sites for long periods of time, like small harbours and/or buildings equipped for warehousing or garaging.
• these assembly/disassembly operations require lots of time and attention in the way with which the various components of the boat are handled so as not to be damaged, creating situations of inconvenience and loss of time.
• connection systems between hulls consisting of hinged beams or folding beams have been described in the prior art: such solutions, however, have proved difficult to carry out and very expensive.
• connection system between hulls consisting of at least one telescopic connection beam is used, so as to be able to reduce the width of the boat from a maximum width to a minimum width.
• Connection means between the hulls consisting of at least one telescopic beam suitable for varying the width of the sailing and/or motor boat with variable width, of the catamaran type, used in the present invention are, for example, those described in the patent GB 2,306,406.
• the telescopic beam therein described is essentially formed from a central body, two intermediate sliding bodies and two peripheral bodies fixed to the hulls.
• the central body having a length similar to the width of the boat in conditions of minimum width, reduces the distance between the hulls by sliding between the two intermediate sliding bodies; these intermediate sliding bodies, having a width approximately equal to that of the hulls, in turn slide along the two peripheral bodies that are each fixed to one of the two hulls.
• the therein described telescopic beam allows the boat to have two configurations: the first, known as sailing configuration, in which the width of the boat is at its maximum; the second, known as rest configuration, for harbourage and/or transportation, wherein the width of the boat is reduced to the minimum, with a width approximately equal to that of the hulls .
• Such a telescopic connection beam is activated/deactivated by an activation element that transmits a movement to such a telescopic beam, this activation element being based upon the use of conventional means for boats like, for example, winches.
• the solution proposed in the patent GB 2,306,406, has the drawback that such a telescopic beam can only be activated/deactivated in certain operating situations wherein the boat is not in the sailing phase. Indeed, the operator that acts upon the activation/deactivation element of the beam described therein can only act in completely calm conditions, like, for example, when the boat is on land or in protected waters, where by protected waters are meant waters sheltered from waves and/or wind, like for example in small harbours.
