Definitions

  • the present invention relates to a multi-hull boat.
  • the present invention relates to a boat of the last type cited, that is to say of the type comprising at least three parallel hulls, each central hull being shorter than the side hulls, and the front end of each central hull being set back by compared to the front ends of the side shells.
  • the object of the invention is to provide a boat whose performance is improved, while requiring propulsion means of reduced power.
  • each hull has a width which increases continuously from its front end to its rear end.
  • the side walls of each shell are substantially vertical and flat.
  • each shell is substantially flat, and inclined from rear to front and from bottom to top, forming with the horizontal an angle of between 0.5 and 5 °.
  • the flat and inclined bottoms of the different hulls offer resistance to air, which will achieve their level of dynamic lift.
  • the angle of these bottoms is advantageously between 1 and 3 °.
  • the face of the floor covering the shells, facing downward is inclined from rear to front and from top to bottom.
  • the face of the floor facing down is substantially parallel to the bottom of the shells.
  • each hull is connected to each side wall thereof, by a flat surface of intermediate inclination, forming a chamfer, the height of this inclined surface decreasing regularly from the rear to the front as a function of the inclination of the bottom, until it vanishes at the front end of the hull .
  • the rear ends of the different hulls are aligned in the same plane transverse to the axis of the boat, and the cross section of the different hulls is the same over the entire length of the latter, up to the end before the shortest hulls.
  • This structure facilitates the realization of the boat, since all the hulls are identical from their rear end to the level of the front end of the shortest hulls, the side hulls simply extending relative to the other hulls, by an area which is more tapered.
  • each tunnel formed between two hulls is equipped with a flap which, articulated at its front end about a horizontal axis, under the connecting floor between the hulls and substantially at mid-length of the boat, is associated to means for adjusting its inclination.
  • Each shutter which can be actuated for example by a jack allows, if necessary is to reinforce the action which results from the inclination of the floors connecting the shells.
  • This boat which may for example have four hulls, or a greater number of hulls is advantageous in view of the lift characteristics which it has, and which make it possible to limit the power of the motorization.
  • They can be conventional propellants or hydrojet type surface propellants. Given the volumes available inside the hulls and the lightness of the assembly, the boat can be made unsinkable by placing an expanded material inside the hulls, for example at thirty kilos per m3.
  • This type of boat is just as suitable for pleasure craft as it is for star type boats for the transport of passengers or commercial boats for the transport of vehicles or containers.
  • the boat shown in the drawing comprises four identical hulls two by two, namely two side hulls 2 and two central hulls (3).
  • the lateral (2) and central (3) shells have posterior ends which are arranged in the same plane transverse to the axis of the boat.
  • each lateral (2) or central (3) shell has a triangular shape in cross-section through a horizontal plane, its width increasing from its front end to its rear end.
  • the two side walls (4) are substantially vertical and planar.
  • the bottom (5) of each shell is substantially flat and inclined from rear to front and from bottom to top, forming with the horizontal an angle of between 0.5 and 5 °, and preferably between 1 and 3 °.
  • the bottom 5 of each shell is connected to the two side walls (4) thereof by a flat surface (6) of intermediate inclination forming a chamfer, the height of this surface (6) decreasing regularly from the rear to the forward depending on the inclination of the bottom. It follows from these forms that the shells are easily achievable, and inexpensive, for example in low density metal alloy such as an aluminum alloy.
  • the shells are held in shape by a certain number of transverse couples (7), some of which have been shown diagrammatically in FIG. 4.
  • the cross section of the different hulls (2,3) is the same over the entire length of these until the front end of the most short. This makes it possible to standardize the manufacture, the two side shells (2) being simply provided with respect to the central shells (3) of a tapered extension forward.
  • the different shells are assembled to each other by couples, and by a floor (8) whose face turned downward is inclined from rear to front and from bottom to top.
  • This characteristic participates with the widening of the hulls from front to rear to reduce the section of air passage between the hulls, which promotes the phenomenon of lift.
  • the boat which has been represented in the drawing has superstructures corresponding to those of a speedboat, but could just as easily have other superstructures, for example insofar as it would be intended to collect it on the surface of the water. pollution waste in which case it would be advisable to have shutters at the level of the tunnels to collect the waste, and transfer it to settling tanks which can be located for example on a beach provided at the rear of the boat.
  • the invention brings a great improvement to the existing technique by providing a boat of simple design, offering very high performance, with a motorization of reduced power. This results in savings both in terms of manufacturing and in terms of operation and maintenance.
  • the number of hulls could be different, the main thing being that the central hulls are shorter than the lateral hulls to ensure this funneling phenomenon which channels the air towards the tunnels formed between the hulls or else that the tunnels could be limited in the upper part by hinged flaps, without departing from the scope of the invention.
