Description

DESCRIPTION

Pleasure boat

Technical field

[0001] The present invention relates to a pleasure boat or craft.

[0002] More particularly, the present invention relates to a luxury pleasure boat, for example a yacht.

Prior art in this field

[0003] Some boats or pleasure boats comprise a hull and a deck in which a superstructure is included that can house or accommodate -for example- the passenger cabin and / or the wheelhouse for the ship owner or owner of the boat.

[0004] In some known types of ship, said structure extends along the entire transverse width of the deck, in such a way that the side walls of said superstructure are practically aligned with the hull on both sides of the ship.

[0005] This configuration (also called 'full beam' or 'maximum beam'; or 'Full Beam', in English) has an advantage: it allows you to maximize the space inside the superstructure, which allows to obtain an environment more spacious and comfortable.

[0006] However, since the superstructure extends along the entire width or width of the deck, this entails the need to pass through or over it when moving from the aft of the deck to the bow of the deck, or vice versa. This is a great drawback, both from a practical point of view and from a point of view related to the privacy of the users, especially when the superstructure houses a passenger cabin.

[0007] In other known types of ship, the superstructure has a width less than the deck, in such a way that passageways or corridors are created on both sides of said superstructure between the side walls of the latter and the side walls of the ship.

[0008] This second configuration (also called 'walk' or 'detour'; or 'Walk Around', in English) has an advantage: it allows you to easily move from the stern to the bow of the deck without having to cross the superstructure .

[0009] On the other hand, it entails a significant decrease in the space that can be used inside the superstructure with respect to the 'maximum beam' configuration.

[0010] In order to find a balance or intermediate solution between the two configurations disclosed above, it is possible to provide a single side passageway to move from the aft of the deck to the fore of the deck while remaining outside the superstructure: on a flank or side of the ship, the side wall of the superstructure is practically glued or aligned with the hull; conversely, on the opposite side of the ship, the superstructure terminates before reaching the hull, leaving a clear passageway on the deck between the opposite side wall of the superstructure and the side wall of the ship.

[0011] On the one hand, this intermediate solution allows greater practicality or functionality when moving from one area of the deck to another and, on the other hand, provides - for a deck with a given size a space within the superstructure that is greater than in the case of a 'detour' configuration. In documents WO 2013/034935 and US 4064 584, for example, boats or pleasure boats are disclosed containing a superstructure with this design

However, even this solution is not free from drawbacks or drawbacks.

[0013] More particularly, the asymmetric arrangement of the superstructure with respect to the hull entails an aerodynamic imbalance, since the boat has a front surface that is exposed to the wind in the direction of navigation and which is not symmetrical with respect to the hull, with the consequent formation of different turbulences on the two opposite sides of the hull. Consequently, instead of moving in a straight line, the boat has a tendency to turn or veer towards the side on which the superstructure is located, that is, towards the side that offers greater resistance to air or wind. Consequently, to keep the boat going straight ahead constantly, it is necessary to make continuous rudder corrections.

[0014] The higher the browsing speed, the more evident this disadvantage becomes. Also, how much The larger the size of the ship, the more obvious this disadvantage becomes.

[0015] It is necessary to avoid this type of disadvantage and inconvenience, especially in luxury pleasure boats (such as yachts), where the high selling price should guarantee optimum performance.

[0016] Likewise, if the ship has an upper bridge or flying bridge on the superstructure, the asymmetric arrangement causes said flying bridge to project or be 'cantilevered' on the side of the lateral passage, which can cause possible fluctuations phenomena of pressure that must be eliminated by increasing the support structures -which would lead to problems related to weight- or by adding separate supports (struts or uprights), which would be unsightly.

In any case, the asymmetrical arrangement of the superstructure with respect to the hull gives the ship a general irregular, clumsy and cumbersome structure and an unpleasant appearance.

[0018] The asymmetrical arrangement cannot be clearly appreciated when looking at the ship from the side. On the contrary, it is evident when the boat is viewed from the front or from behind, for example when the boat is docked and has the bow or stern facing the dock.

[0019] Again, this disadvantage is of great importance in the case of yachts and other luxury pleasure boats, in which the appearance or appearance is one of the parameters that determine the success (or failure) of a model in the market.

Consequently, and despite the practical advantages that can be obtained, a solution that opts for an asymmetrical arrangement of the superstructure with respect to the deck is unfeasible, at least with regard to its application in luxury boats such as the yachts, in which high standards are required both from a technical point of view and from an aesthetic point of view.

[0021] The document 'X-Sym 125 Yacht with asymmetrical design and exclusive curves by S-move design | Tuvie '(http://www.tuvie.com/x-sym-125-yacht-with-asymmetrical-design-and-exclusive-curves-by-s-move-design/) and the document' Beneteau Swift Trawler 30 - Reviews, performances, compare, price, warranty, specs, Reports Specifications Layout, video | BoatTEST.com '(https://www.boattest.com/review/beneteau/3493_swift-trawler-30) unveil pleasure boats that incorporate symmetrical and asymmetric components.

[0022] However, in the pleasure boats shown in these documents, the simultaneous presence of symmetrical and asymmetric elements has a purely aesthetic purpose.

None of these documents solves the technical problem of eliminating aerodynamic imbalance due to the fact that the ship or vessel has a front surface that is exposed to the wind in the sailing direction and that is not symmetrical with respect to the hull.

[0024] Therefore, none of these documents provides a pleasure boat with a structure capable of effectively eliminating the mentioned aerodynamic imbalance.

[0025] The main objective of the present invention is to solve the disadvantages and disadvantages of the prior art in this field by providing a pleasure boat that allows to combine advantageous practical solutions with directional stability during navigation and with an attractive and pleasant appearance. This and other objectives for the pleasure boat are achieved as claimed in the appended claims.

Summary of the invention

[0026] The pleasure boat -or pleasure boat- according to the present invention comprises a hull and a deck in which a superstructure is included which is arranged asymmetrically with respect to the plane of symmetry (that is, the plane located in the fore-aft direction) of said ship, in such a way that, on a first flank or side of the ship, the lateral wall of the superstructure is practically glued or aligned with the hull, while on a second flank or opposite side, it is creates a free walkway or passageway on the deck between the side wall of the superstructure and the side wall of the ship.

Thanks to the fact that the present invention provides at least one bulkhead that extends from said second side of the hull in a direction that is practically transverse to the plane of symmetry of the ship and has a suitably selected width - or width -, the frontal surface that opposes the wind in the navigation direction contains practically no gap or space between said bulkhead and said superstructure.

Thanks to this solution, any imbalance (even the slightest) in the aerodynamic profile of the boat is compensated, so that the boat does not have any tendency to deviate from its predetermined route during navigation.

[0029] Likewise, and also thanks to the bulkhead according to the present invention, when an observer looks at the ship in a direction parallel to the plane of symmetry of the ship itself, due to the previously explained solution, the optical effect for the observer is that the general structure is practically symmetrical.

Consequently, thanks to the invention, the asymmetric arrangement of the superstructure does not adversely affect the aerodynamic profile or the aesthetic appearance of the ship and all the practical advantages derived from this arrangement can be fully exploited, so which, at the same time, maintain directional stability during navigation (without the need for continuous corrections) and a prestigious appearance.

[0031] The mentioned -at least one- bulkhead is practically coplanar with one of the transverse walls of the superstructure, more particularly the transverse wall of the forward side.

[0032] In this way, the bulkhead functions as a deflector and provides -on its side of the hull- an aerodynamic behavior that is very similar to that provided by the superstructure on the opposite side of the hull, thus eliminating (or, at least, reducing drastically) the imbalance in the aerodynamic profile.

[0033] In a preferred embodiment of the invention, said -at least one- bulkhead has practically an 'L' shape and comprises a first wall that is practically coplanar with respect to one of the transverse walls of the superstructure -specifically, the forward-side transverse wall - and a second wall that is substantially orthogonal to the first wall and extends along the flank or side of the hull toward the center of the superstructure.

In fact, experimental tests have shown that a bulkhead that only includes the first wall -which is practically coplanar with respect to one of the transverse walls of the superstructure- may not be enough to eliminate the tendency of the ship to deviate. of the predetermined route, while in the case of an 'L' shaped bulkhead, the second wall - which runs along the flank or side of the hull effectively contributes to ensuring a satisfactory aerodynamic profile.

[0035] In a preferred embodiment of the invention, two bulkheads are provided: one of them is practically coplanar with the transverse wall of the superstructure on the forward side and the other is practically coplanar with the transverse wall of the superstructure on the forward side. aft.

[0036] In a particularly preferred variant of the aforementioned embodiment, the aforementioned bulkheads both have practically an 'L' shape and comprise a first wall -which is practically coplanar with the corresponding transverse wall of the superstructure- and a second wall -which it is practically orthogonal to the first wall and extends along the flank or side of the hull towards the center of the superstructure.

[0037] In a preferred embodiment of the invention, an upper bridge or flying bridge is provided on the superstructure, such that this flying bridge extends transversely over the entire width or width of the wheelhouse, from one side of the ship to the other. ; thanks to the presence of said flying bridge, the asymmetric arrangement of the superstructure is not visible when the ship is observed from above.

[0038] Advantageously, when a flying bridge is provided, the -at least one- bulkhead of the ship according to the present invention plays an important structural role, since it supports the side of the flying bridge that is opposite to the side on the that the superstructure is located; In the absence of such a bulkhead, the flying bridge would be cantilevered on the underlying superstructure (narrower), which would cause considerable bending stresses or would make it necessary to increase the support structures -which would lead to problems related to weight- or add supports separated and unsightly.

Detailed description of some preferred embodiments

[0040] Referring to Figures 1 to 4, a pleasure boat -or pleasure boat- according to a first embodiment of the invention is shown, so that said boat is indicated as a whole by reference number 1.

The ship or vessel 1 comprises a hull 3, in which a bow 3a, a stern 3b and two flanks or sides 3c, 3d are detailed, which connect the bow 3a and the stern 3b on opposite sides of the hull 3.

The ship 1 also comprises a deck 5, in which a superstructure 7 is included whose function is to house or accommodate one or more passenger cabins and / or wheelhouses for the ship owner or owner of the ship.

[0043] According to the invention, the superstructure 7 is arranged on the deck 5 in an asymmetric position with respect to the plane of symmetry L of the ship 1, that is, the plane that is perpendicular to the deck 5 and passes through the bow 3a and the midpoint - or intermediate point - of the stern 3b. More particularly, the outer perimeter of the aforementioned superstructure 7 comprises: a first lateral wall 7c that extends for a section -or length- determined along a first flank or side 3c of the hull between the bow and the stern, so which is basically aligned with the mentioned first side of the hull; a first transverse wall 7a extending from the forward facing end of said first side wall 7c in a direction substantially transverse to the plane of symmetry L of the ship; a second transverse wall 7b extending from the aft-facing end of said first side wall 7c in a direction substantially transverse to the plane of symmetry L of the ship; a second side wall 7d connecting the ends of the transverse walls 7a, 7b opposite those that are connected to the first side wall 7c.

[0044] The distance between the side walls 7c, 7d of the superstructure 7 -or, in other words, the width or width W of the superstructure- along an axis that is transverse to the plane of symmetry L of the ship is, at each point of the superstructure, less than the distance between the flanks or sides 3c, 3d of the hull 3 -or, in other words, than the width or width W of the deck 5- along an axis that is transverse to the plane of symmetry L of the ship, in such a way that there is a free lateral passage 9 in the deck 5 between the second lateral wall 7d of the superstructure 7 and the second side 3d of the hull 3. Said lateral passage must have a sufficient width to allow the passage of at least one person.

In any case, in order to obtain sufficient space in the superstructure 7, said superstructure must extend -in a direction perpendicular to the plane of symmetry L- from the first side 3c of the hull to the second side 3d of the hull, beyond of the aforementioned plane of symmetry, at least along a significant part or portion of its length.

Also, for reasons that will become apparent later, preferably the superstructure 7 does not have a uniform width or width in the direction perpendicular to the plane of symmetry L of the ship, but rather has a reduced width - that is, it is conical or tapered. - at least at one of its ends in the longitudinal direction.

[0047] More particularly, in the preferred embodiment shown in Figures 1 to 4, the superstructure 7 comprises a part or portion with a reduced width at the end facing the bow of the ship. Accordingly, the width or width of the first transverse wall 7a is less than the width or width of the second transverse wall 7b in a direction that is transverse to the plane of symmetry L of the ship, and the second side wall 7d comprises a first part or portion 7d 'that extends from the end of the second transverse wall 7b in a direction that is basically parallel to the plane of symmetry L of the ship and a second portion 7d' 'that extends in an oblique direction and joins the first portion 7d 'of the second side wall 7d with the first transverse wall 7a. In other words, the plane of the superstructure 7 is in the shape of a rectangle with a scalene trapezoid superimposed, so that its smallest base faces forward (see Figure 3).

[0048] This configuration is not intended to be limiting in any way and therefore different variants are also possible. For example, instead of being made up of two parts or portions with different orientations, the second side wall 7d of the superstructure 7 could have a profile that curves towards the bow.

[0049] In general, the first transverse wall 7a has a width along an axis perpendicular to the plane of symmetry L that is less than the maximum width W '' of the superstructure 7, that is, relative to the maximum distance between said first side wall and said second side wall of said superstructure along an axis that is perpendicular to the plane of symmetry L.

Taking the above into account, it is clear that the pleasure boat 1 according to the invention has a general structure that is clearly asymmetrical.

[0051] Said asymmetry is relevant when the ship is observed from the front (or from behind), that is, in a direction that is parallel to the plane of symmetry L (fore-aft direction).

[0052] As previously explained, the asymmetric arrangement of the superstructure 7 entails relevant practical advantages and, more particularly, makes it possible to increase the available space within the aforementioned structure compared to a symmetrical arrangement with lateral passageways on both sides ( configuration 'of paseo' or 'of rodeo'; or 'Walk Around Configuration', in English). More specifically, for a deck with the same size, in the ship according to the invention the space inside the superstructure 7 can be 12-15% greater than in a 'rodeo' configuration.

However, the asymmetric arrangement of the superstructure 7 causes an imbalance from the point of view of aerodynamics, since the part or portion of the ship located between the plane of symmetry L and the side 3c of the hull 3 (that is , the part completely occupied by the superstructure 7) offers a significantly greater resistance to air or wind than the part of the ship located between the plane of symmetry L and the opposite side 3d of the hull 3 (that is, the part only partially occupied by the superstructure 7), so that different turbulences are created on the two opposite sides of the hull; the greater the speed of the ship and the greater the size of the ship, the more pronounced or relevant the effects of the aforementioned imbalance will be.

[0054] Also, the asymmetrical arrangement of the superstructure 7 gives the ship 1 a clumsy and inelegant profile and causes a bad impression on the observer from an aesthetic point of view.

[0055] To eliminate this imbalance in the aerodynamic profile and hide the asymmetric arrangement of the superstructure 7, the pleasure boat 1 according to the present invention has the presence of a bulkhead 11 on the deck 5, so that the bulkhead comprises at least a first wall 11a that extends from the second flank or side 3d of the hull 3 in a direction that is basically transverse to the plane of symmetry L of the ship 1 and basically coplanar with the first transverse wall 7a of the superstructure 7, of so that it has a width such that the distance d of the end of said first wall 11a of said bulkhead 11 adjacent to the first transverse wall 7a of the superstructure 7 from the plane of symmetry L of the ship is equal to or less than the maximum distance d 'of the second lateral side 7d of the superstructure 7 from said plane of symmetry L.

[0056] Preferably, the height of the first wall 11a of the bulkhead 11 is practically equal to the height of the walls 7a-7d of the superstructure 7.

Thanks to this solution, when the ship 1 is viewed from the front, there is no gap or space between the wall 11a of the bulkhead 11 and the superstructure 7, so that the aforementioned bulkhead functions as a deflector and the ship presents in the air or the wind a symmetrical and practically continuous impact surface, thus eliminating any imbalance in the aerodynamic profile and giving the boat directional stability as a result.

[0058] Likewise, the presence of the bulkhead 11 reduces the impression of a strong asymmetry on the observer and causes a more pleasant impression on said observer.

Taking into account the presence of the bulkhead 11, for those skilled in this field it will be clear why the superstructure 7 has a part or portion with a reduced width at the end facing forward, that is, close to the aforementioned first transverse wall 7a; Thanks to this configuration, the lateral passage 9 extends continuously from the stern to the bow, without it being necessary to include doors or passages in the first wall 11a of the bulkhead 11. More particularly, said lateral passage 9 comprises a first part or portion 9 'that extends along the first part or portion 7d' of the second side wall 7d in a direction that is basically parallel to the plane of symmetry L of the ship, and a second part or portion 9 '' that is extends along the second part or portion 7d '' of the second side wall 7d in an oblique direction; the opening 9a of the lateral passage 9 towards the bow, which extends between the first transverse wall 7a of the superstructure 7 and the first wall 11a of the bulkhead 11, must be at a distance from the plane of symmetry L of the ship that is less than the maximum distance between said plane of symmetry L and the second lateral wall 7d of the superstructure 7.

[0060] Advantageously, as can be seen in Figure 3, the opening 9a of the lateral passage 9 is located in a central position with respect to the direction transverse to the plane of symmetry L (that is, 'straddling' the mentioned plane of symmetry), which further contributes to eliminating asymmetries in the aerodynamic profile of the pleasure boat 1.

[0061] As can be seen in Figure 4, despite the asymmetrical arrangement of the superstructure 7, when the pleasure boat 1 according to the invention is viewed from the front, it can be seen that it offers the best possible approach to a surface continuous front, which is formed by -in sequence- the first transverse wall 7a of the superstructure 7, the second portion 7d '' of the second lateral wall 7d of said superstructure (visible behind the opening 9a of the side passage 9) and the first wall 11a of bulkhead 11.

[0062] A door (eg a sliding door or a revolving door) can be included in the opening 9a of the side passage 9 to increase the symmetry of the structure.

[0063] In the preferred embodiment shown in Figures 1 to 4, the bulkhead 11 has a profile basically with an 'L' shape and comprises -in addition to the first wall 11a- a second wall 11b that extends along along the second side 3d of the hull 3 in a direction basically orthogonal to said first wall 11a and towards the stern 3b.

[0064] The presence of said second wall 11b contributes to 'accompanying' the air flow along the flank or side 3d of the helmet, symmetrically to what occurs along the opposite side 3c of the helmet thanks to the presence of the lateral wall 7c of the superstructure 7.

[0065] Also, advantageously, said second wall 11b can hide from an external observer -who is viewing the ship from the side- the presence of an access door (not shown in the Figures) to the superstructure 7 in the second portion 7d '' of the second side wall 7d.

[0066] Preferably, the bulkhead 11 also comprises a third wall 11c which extends parallel to the second portion 7d '' of the second side wall 7d of the superstructure 7 and joins the free ends of the said first wall and the said second wall 11a, 11b of the aforementioned bulkhead.

Thanks to this arrangement, the free side passage 9 has a practically uniform width over its entire length.

Also, advantageously, the volume contained between the walls 11a-11c of the bulkhead 11 can be used as storage space, for example for docking equipment and / or safety equipment.

[0069] In the embodiment shown in Figures 1 to 4, the ship 1 also comprises an elevated bridge or flying bridge 13 that covers the superstructure 7 and extends in a direction transverse to the plane of symmetry L of the ship over the entire deck width 5.

Thanks to the presence of this flying bridge 13, the asymmetric arrangement of the superstructure 7 is not visible when the ship 1 according to the present invention is viewed from above.

Advantageously, in this embodiment, the bulkhead 11 functions as a support or support for the flying bridge 13 near the forward-facing end, on the side of the deck that is opposite the side on which the superstructure 7. A support or strut 15 may also be included to support the flybridge 13 near the aft-facing end.

[0072] In this embodiment, the bulkhead 11 performs an important structural function, since, in its absence, the flying bridge 13 would be 'cantilevered' on the underlying superstructure 7, which would cause considerable bending stresses or make it necessary to increase support structures - with a corresponding increase in weight - or add separate and unsightly supports.

[0073] In a preferred embodiment of the invention, the bulkhead 11 is attached or mounted on the deck 5 in a fixed and permanent way.

However, in an alternative embodiment of the invention, said bulkhead can be mounted on deck 5 so that it can be moved or even removed.

Referring now to Figures 5 and 6, a second embodiment of the pleasure boat 1 according to the present invention is shown schematically.

[0076] The aforementioned second embodiment differs from the embodiment described above by the fact that it provides two bulkheads 11,21: one, at the end of the superstructure facing forward 7 and, the other, at the end of the superstructure 7 looking aft.

[0077] Thanks to the presence of the aforementioned bulkheads, the ship has a practically continuous surface both at the bow and stern and the visual sensation of a symmetrical surface is very noticeable, both when the ship is viewed from the front and when viewed from behind. .

Also in this second embodiment, the superstructure 7 is arranged on the deck 5 in an asymmetric position and the width of the superstructure 7 in a direction transverse to the plane of symmetry L of the ship - that is, the maximum distance between the walls 7c, 7d of the aforementioned superstructure- is, at each point of the superstructure 7, less than the width of the deck 5 in a direction transverse to the plane of symmetry L of the ship, in such a way that there is a free lateral passage 9 between the second side wall 7d of the superstructure 7 and the second side 3d of the hull 3.

[0079] In this embodiment, the superstructure 7 comprises a first part or portion with a reduced width at the forward-facing end and a second part or portion with a reduced width at the forward-facing end. Stern. Thus, the second side wall 7d of said superstructure comprises a first central or intermediate portion 7d 'that extends in a direction that is basically parallel to the plane of symmetry L of the ship; a second portion 7d '' extending in an oblique direction and joining the first portion 7d 'of the second side wall 7d with the first transverse wall 7a; and a third portion 7d '"which extends in an oblique direction and connects the first portion 7d' of the second side wall 7d with the second transverse wall 7b. In this embodiment, a first bulkhead 11 is included in the deck 5, which comprises at least a first wall 11a that is basically coplanar with the first transverse wall 7a of the superstructure 7 and extends from the second flank or side 3d of the hull 3 in a direction that is basically transverse to the plane of symmetry L of the ship 1 and having a width such that the distance of the end of said first wall 11a of said bulkhead 11 adjacent to the first transverse wall 7a of the superstructure 7 from the plane of symmetry L of the ship is equal to or less than the maximum distance of the second side wall 7d of the superstructure 7 from said plane of symmetry L; the deck 5 also includes a second bulkhead 21, which comprises at least one first wall 21a which is basically e coplanar with the second transverse wall 7b of the superstructure 7 and extends from the second flank or side 3d of the hull 3 in a direction that is basically transverse to the plane of symmetry L of the ship 1 and that has a width such that the distance from the end of said first wall 21a of said bulkhead 21 adjacent to the second transverse wall 7b of the superstructure 7 from the plane of symmetry L of the ship is equal to or less than the maximum distance of the second side wall 7d of the superstructure 7 from the mentioned plane of symmetry L.

[0080] Preferably, the height of the primary walls 11a, 21a of the aforementioned bulkheads 11, 21 is equal to the height of the walls 7a-7d of the superstructure 7. Therefore, the side passage 9 extends continuously from the stern to the bow and comprises a central or intermediate portion 9 'that extends in a direction that is basically parallel to the plane of symmetry L of the ship, and two oblique portions 9' ', 9' '' that extend -respectively - along the second portion and the third portion 7d ", 7d" 'of the second side wall 7d. The openings 9a, 9b of the lateral passage 9 towards the bow and the stern must be at a distance from the plane of symmetry L of the ship that is less than the maximum distance between the mentioned second lateral wall 7d of the superstructure 7 and the mentioned plane of symmetry L.

Consequently, and despite the asymmetrical arrangement of the superstructure 7, an observer who sees the pleasure boat 1 according to the present invention from the front or from behind will have the impression of observing a continuous surface.

Also in this embodiment, each bulkhead 11, 21 has a profile basically with an 'L' shape and comprises -in addition to the first wall 11a, 21a- a second wall 11b, 21b that extends along the second flank or side 3d of the hull 3 in a direction basically orthogonal to said first wall 11a, 21a and towards the center of the superstructure 7, that is, towards the stern and towards the bow, respectively. Preferably, each bulkhead 11, 21 also comprises a third wall 11c, 21c connecting the free ends of the corresponding walls of each bulkhead and delimiting a corresponding closed volume that can be advantageously used as storage space.

[0083] Also in this embodiment, the bulkheads 11,21 are fixed or permanently mounted on the deck 5, but, in an alternative embodiment, they can be mounted on the deck 5 so that they can be moved or even removed.

[0084] If the ship 1 includes a flying bridge 13 that covers the superstructure 7 and extends in a direction transverse to the plane of symmetry L of the ship over the entire width of the deck 5, the bulkheads 11, 21 function as supports or supports for the flying bridge 13, both at the stern and at the bow, such that the flying bridge is not 'cantilevered' on the underlying superstructure and there is no need for the presence of separate supports or uprights or to increase the supporting structures, with consequent weight gain.

Referring -in particular- to Figure 6, some preferred proportions are provided between the different elements or components of the ship according to the present invention (and, more particularly, between the superstructure 7 and the bulkheads 11, 21), so it should not be understood that said proportions are limiting in any way:

-The ratio or proportion between the distance of the end of the first transverse wall 7a of the superstructure 7 from the plane of symmetry L (segment ED of Figure 6) and the corresponding distance of the second flank or side 3d of the hull 3 from the mentioned plane of symmetry L (segment E ^b of Figure 6) is between 0.3 and 0.6; This ratio can be considered as an 'asymmetry index' of the configuration of the boat according to the invention;

-The minimum width of the first wall 11a of the bulkhead 11 is equal to the distance between the second flank or side 3d of the hull 3 and the projection of the point furthest from the plane of symmetry L of the second side wall 7d of the superstructure 7 (A) on said first wall 11a of bulkhead 11 and, therefore, corresponds to segment A'B of Figure 6; preferably, the width of the first wall 11a of the bulkhead 11 (segment CB 'of Figure 6) is equal to said minimum width plus the so-called' coverage factor 'or' cover factor '(segment CA' of Figure 6 ).

-Preferably, said 'coverage factor' (segment CA 'of Figure 6) is equal to 15-40% of the distance between the end of the first transverse wall 7a of the superstructure 7 and the projection of the point furthest from the plane of symmetry L of the second lateral wall 7d of the superstructure 7 (A) on the first wall 11a of the bulkhead 11 (segment DA 'of Figure 6);

-Preferably, the angle at which is formed between the second oblique portion 9 '' of the lateral passage 9 and the first portion 9 'of said lateral passage -and the plane of symmetry L of the ship 1- is equal to 20-45 °; -Preferably, the ratio or proportion between the width b1 of the second oblique portion 9 '' of the lateral passage 9 and the width b of the first portion 9 'of said lateral passage is between 0.9 and 1.1.

[0086] Similar proportions can also be envisaged for the second bulkhead 21.

Thanks to all the foregoing, it is evident that the pleasure boat according to the invention allows to achieve the objectives specified above and combines the practical advantages derived from an asymmetric arrangement superstructure with a practically symmetrical aerodynamic profile and good stability. directional and a nice appearance.

[0088] For those skilled in this field, it will also be clear that the detailed description previously provided has been offered by way of non-limiting example, so that it is possible to introduce various variants and modifications without departing from the scope of protection, such as and as specified in the appended claims.
