Abstract

The invention relates to a boat hull 100. Such a hull 100 essentially comprises a central keel 1 and two lateral keels 2, 3 delimiting two tunnels 4, 5 each having their axis shifted towards the outside of the hull 100 instead of being centred. A step 6 and a shield 10 are used to deflect sea spray. The understructure of such a boat makes it possible to install in the cabin a panel capable of assuming a horizontal position in which it can be used as a table and a vertical position in which it can be used as a partition, thus delimiting two separate sleeping areas. The invention is applied in particular to yachting where comfort, cost-effectiveness and stability are especially desired. <IMAGE>

Description

BOAT HULL AND INTERIOR EQUIPMENT
FROM SUCH A BOAT
The invention relates to a light displacement motor boat hull. It also relates to a particular arrangement of the cabin of such a boat.

 A hull according to the invention is similar to hulls called "seagull wings", but it provides, thanks to its completely new profile, at equal speed, greater comfort and lower energy consumption than hulls of known type . The latter, in fact, tend to pitch up at the start, pushing the water, which leads to energy consumption, and it is only when a sufficient speed is reached, that it transplanted from the nose to because of the weight of the front part which is out of the water.

 The purpose of the present invention is to overcome these drawbacks, because its profile means that it progressively adjusts as a function of the speed of the boat while keeping an attitude which is always horizontal, hence greater comfort. The object of the invention is also, thanks to the new hull profile concerned, to free up a useful volume interesting the layout of the cabin, the same space can be transformed alternately either into two independent double berths or into a square, (dining area ) thanks to a mobile double-function panel.

 The invention relates more precisely to a hull (100) of a boat of the so-called seagull type, characterized in that it comprises a central keel (1) and two side keel (2, 3) delimiting two tunnels (4, 5) .

The invention will be better understood with the aid of the explanations which follow and of the appended figures among which
- Figure 1 is a section of a hull according to
the invention which schematically illustrates its
essential features
- Figure 2 schematically illustrates a view of
profile of this hull
- Figure 3 is a half view from below of said
hull according to F
- Figure 4 shows a half profile of this
hull according to the different levels of
section, the other half profile being symmetrical with the
first
- Figures 5 and 6 show a device
interior layout.

For the sake of clarity, the same elements bear the reference files in all the figures. A first important characteristic of the invention is illustrated by means of FIG. 1 which is a typical section of the hull (100). This section reveals the existence of a first keel, known as the central keel (1) and two so-called lateral skittles (2) and (3), which delimit between them and the central keel (1) two tunnels (4) and (5) whose axes are not in the middle but slightly offset towards the outside of the hull (100).

The waterline is referenced (Lf). In addition, a step (6), extended by a visor (10), acts as a deflector and prevents spray from passing over the bridge. The evolution of the profile of the hull (100), the tunnels (4) and (5) and the central and lateral keels (l, 2,3) is illustrated by means of Figures 2, 3 and 4. Figures 2 and 3 respectively illustrate, seen in profile and seen from below, a boat whose hull (100) is produced in accordance with the invention. FIG. 4 is a schematic representation of the different profiles of said hull (100) seen according to a succession of sections made in vertical and transverse planes (a), (b), (c), (d), (e), ( f) extending from the vicinity of the stern of the boat to the bow. For greater clarity, reference is made in the following description, either to one or the other of these figures (2 , 3,4). We find there in particular, in addition to the steps (6) supplemented by the visor (10), the central keel (1) and one of the side pins (3), the second not being visible since it is a question of half-cut and half-section.

 At the level of the section in the plane (b)> of the hull (100) located towards the front of the boat, the depth and profile of each tunnel (4) and (5) (tunnel 5 being the only one visible) shows that it is indeed a real channel through which water rushes.

Starting very quickly after the brion, each tunnel (4,5) has a very tight upper water line, close to the water line (Lf).

 Towards the rear of the boat, about one meter in front of the plane (a), there is a lowering of the roof of said tunnel (4,5) below the waterline.

This architecture leads to the production of a profile acting as a flap more commonly known as "Flap" in naval architecture, integrated into the hull, which avoids the installation of reported "Flaps".

 Thanks to the profile of these tunnels (3,4) delimited between the three central (1) and lateral (2,3) keels, the water which rushes in from the front is compressed instead of being deflected as it is the case for classic hulls of the type known as "seagull wings".

These indeed have only one central keel and two lateral elements which act as a stabilizing float but do not allow the formation of tunnels as marked as those revealed by the present invention.

 Such an architecture with its three keels delimiting the two tunnels (4,5) described above leads to the production of a hull (100) whose longitudinal attitude remains perfectly horizontal: it progressively adjusts according to the speed of the boat without push water. Knowing that the resistance to the advancement of the boat is proportional to the square of the wet surface and to the volume of water displaced, it is understandable that the energy consumption is reduced thanks to this hull.

 These performances having been acquired, the hull (100) according to the invention has three other interesting characteristics. Firstly, thanks to its three keels, the boat stalls very little and the penetration due to the load remains low. Secondly, the side keels provide excellent transverse stability: the boat does not roll. Third, the hull offers usable volume from the front of the boat.

 A spacious cabin (51) can be fitted out there, in particular thanks to the use of a device capable of transforming a given space, either into two independent double berths, or into a square as is better explained by means of FIGS. 5 and 6. There are inserted in the cabin (51) two sofa-beds (52, 53) with files (56, 57) and an element called partition-table (55) because of the two functions that it performs. A frame (60) acting as a fixed partition divides the space concerned in two. In this fixed partition (60) is provided a plate (62) capable of pivoting about a horizontal axis (63) located in the plane of the fixed partition (60).

In the vertical position (figure 6), the mobile platform
(62) obscures the cutout (70) made in the fixed partition
(60), which results in delimiting two volumes making it possible to use the benches (52, 53) and backrests (56, 57) in their double bed function, each of these beds being separated from the other by a vertical partition (60, 62).

On the other hand, in a horizontal position (FIG. 5), the movable tray (62) serves as a table for the occupants seated on the benches (52, 53) with backrests (56, 57). Locking systems (not shown) hold
the plate (62) in either of its positions.

 Qn obtains thanks to the invention a boat attractive in many respects: energy saving, stability at sea, high speed, spacious layout, shallow draft etc ... It therefore lends itself to a large number of 'applications for both sea navigation and river navigation.
