Definitions
- the invention relates to a motor boat, of the planing hull type.
- the search for high performance in motor boating leads to the use of either so-called deep V hulls, which have reduced habitability, low stability at high speed and which are sensitive to roll, or of the catamaran type, whose marine qualities and performances are appreciated, but which also have a reduced habitability, in particular in the average sizes, of 6 to 12 meters approximately for example.
- the object of the present invention is in particular to avoid these drawbacks of the current technique, while retaining or improving its advantages.
- the hull has a W-shaped cross section and includes a longitudinal central tunnel in the shape of an inverted V which extends over substantially the entire length of the hull. and the bottom of which is substantially at the waterline.
- the hull according to the invention combines the advantages of habitability of a large V-hull with the advantages of stability and performance of a catamaran and allows, for the same draft and the same width, to increase the surface. bearing.
- the invention also makes it possible, for the same length, to increase the width of the hull and consequently its habitability, while retaining identical performance and speed potential.
- the shape of the hull allows stranding in a stable horizontal position, without the risk of lateral tilting.
- the bow is truncated, which allows the central tunnel to extend to the foremost part of the hull, substantially retaining its shape
- the angle of the tunnel walls is constant over substantially the entire length of the hull
- - the bottom line of the tunnel can be slightly inclined downwards from the bow to the stern, to generate a longitudinal lift and improve the attitude horizontal of the moving boat
- - a transverse fin of the hydrofoil type is mounted between the walls of the tunnel in the rear part of the hull to generate additional lift in the stern and at least partially compensate for the weight of the engines.
- the invention applies to motor boats, civil or military, as well as to machines of the "marine motorcycles" type (jet skis, jet skis and others) and makes it possible to increase their habitability, their stability and their performance.
- FIG. 1 is a schematic front view of a shell according to the invention.
- FIG. 2 is a bottom view of this shell;
- Figure 3 is a side view of this shell;
- Figure 4 is a perspective view of this shell;
- 5 - Figure 5 is a schematic cross-sectional view of an alternative embodiment;
- Figures 6, 7, 8 and 9 are views corresponding to Figures la 4, but show another alternative embodiment of the invention;
- FIGS 6 7, 8 and 9 are views corresponding to Figures la 4, but show another alternative embodiment of the invention;
- FIG. 10 is a schematic front view of another alternative embodiment;
- FIG. 11 is a partial schematic side view corresponding to FIG. 10.
- the hull comprises four longitudinal faces 10, 12, 14, 16, that is to say which extend to 1 'forward to the back of the hull and which form a W
- These faces are substantially flat and two to two symmetrical with respect to longitudinal vertical planes passing through the vertices of the W. More specifically, an outer face 10 and a face
- median faces 12 and 14 are symmetrical with respect to a median longitudinal vertical plane 20, and the face
- the bow 28 is truncated transversely, so that the central tunnel forms by the faces 12 and 14 facing the most forward part of the hull, the faces 12 and 14 retaining the same angle over almost the entire length of the hull and slightly flaring in the immediate vicinity of the bow.
- the hull may include, as shown schematically, an outer step 30 which extends from the stern to the vicinity of the bow but without "going to the latter. The latter can then take a slightly ovoid shape for a skill maximum.
- Strakes 32 projecting, as shown in FIG. 1, or re-entrant (FIG. 5),
- outer step 25 can also be formed on the outer faces 10 and 16, as well as on the median faces 12 and 14, and extend from the stern to the vicinity of the front end of the outer step 30.
- the outer step 30 and strakes 32 are also formed on the outer faces 10 and 16, as well as on the median faces 12 and 14, and extend from the stern to the vicinity of the front end of the outer step 30.
- the outer step 30 and strakes 32 are also formed on the outer faces 10 and 16, as well as on the median faces 12 and 14, and extend from the stern to the vicinity of the front end of the outer step 30.
- the hull according to the invention has a bearing surface which is greater than that of a V-shaped hull which would have the same draft and the same width.
- the hull always has a W shape in cross section, but the outer faces 10 and 16 are no longer symmetrical with the middle faces 12 and 14 with respect to the longitudinal vertical planes 18 and 22 respectively, the median faces 12 to 14 however remaining symmetrical to each other with respect to the median longitudinal vertical plane 20.
- the angles of the median faces 14, 16 with the vertical are less than the angles of the faces 10, 16 with the vertical.
- external steps 30 can be formed on the external faces 10, 16 of the hull and extend from the stern to the vicinity of the bow, or Dier extend to the bow.
- strakes 32 can be formed on the outer faces 10 and
- transverse fin 34 of hydrofoil type which is immersed and whose curved profile has a concavity turned downwards, to increase the lift at the rear of the hull and at least partially compensate for the weight of the engines.
- This fin can be removably mounted between the faces 14, 16 of the hull.
- a hull according to the invention has the following advantages, in addition to those already mentioned of greater stability, increased habitability and grounding in a stable horizontal position:
