Definitions

  • the present invention relates to a boat with several hulls, such as a sailing boat intended for fast cruising, or a cruising motor boat or intended for professional use.
  • the most common boats are monohulls, which have the advantage of being simple to make, of being solid, but which are relatively slow and, in the case of sailboats, sail with a large list affecting the comfort of the passengers.
  • a trimaran has a main central hull and two lateral floats generally shorter than the central hull and of a volume much smaller than this. Only the central hull is habitable, which limits the possibilities of fitting out such a boat. In practice, the boat sails on two floats, namely the central hull and the leeward float. A trimaran allows a faster navigation than a monohull, flatter than this one, but with risks of charging the float downwind.
  • a catamaran has two identical hulls joined by link arms. It is a high-performance boat, whose speed is slightly higher than that of a trimaran with bearing gaits, but less important upwind, and allowing flat navigation in the case of a sailboat.
  • Catamarans have, however, the drawback of requiring very careful construction, in particular because of the stresses which the connecting arms undergo, one of which supports the mast.
  • the present invention aims to remedy these drawbacks, by providing an efficient, safe boat, and allowing comfortable interior fittings.
  • the boat it concerns includes four hulls parallel, of which the two central shells have a length different from that of the two lateral shells, the rear ends of the four shells being situated substantially in the same plane.
  • the central hulls have a length less than that of the lateral hulls.
  • the central hulls have a length greater than that of the side hulls.
  • This arrangement and in particular the arrangement of the various hulls ensure: - a damping of the effect of charging the hulls into the waves, the reaction of a wave on the central hulls occurring at a time different from that of the reaction on the side hulls, - a reduction in the effect of "striking" of the waves under the nacelle located in the central part of the boat, - a reduction in dunnage, since the central hulls are protected from the effects of the wind by the side hulls.
  • this arrangement allows, taking into account the buoyancy of the four hulls, a reduction in the draft, which can be of a value of 0.40 to 0.60 meters while the draft of a corresponding catamaran is 0.8 to 1 meter.
  • the connections between them are easier to make, which allows the structure to be lightened with the possibility of dismantling the link arms.
  • each hull being equipped with a rudder, these can be of small surface, taking into account that the directional effort is very reduced. Finally, in the event of deterioration of a hull, the boat can continue to sail in perfect safety on the other three hulls, these safety conditions can be further improved by compartmentalizing the different hulls using watertight bulkheads.
  • the draft of the central hulls is substantially the same as that of the lateral hulls.
  • the central hulls are more tapered than the lateral hulls.
  • This arrangement makes it possible, in combination with the directional effect provided by the four hulls, not to equip the boat with daggerboards, all of the hulls ensuring perfect directional stability.
  • the link arms are used for mounting hydrofoil wings whose supports are vertical and profiled.
  • a hydrofoil wing is disposed between the two central hulls near the front end of the latter and two hydrofoil wings are arranged in the two lateral corridors delimited by the central hulls and the side hulls, in the rear center part of the boat.
  • the hulls delimit corridors constituting water circulation paths reinforcing the effect of the hydrofoil wings.
  • the location of the wings between the shells ensures their protection against impacts due to foreign bodies.
  • the four hulls are connected at least in the central and rear part of the boat, by nacelles arranged above the waterline, connecting, on the one hand, the two central hulls and, on the other share, each central hull and the corresponding lateral hull, the central nacelle containing the cockpit and the saloon, the central hulls forming passageways serving the cabins which are arranged in the lateral nacelles, and the lateral hulls forming the technical zones containing the engines, generator, fuel and water tanks.
  • Such an arrangement is extremely comfortable for the user by allowing him to move around in the central hulls while benefiting from a large height under beam, and by reporting nuisances, such as engine noise and fuel odors in uninhabited areas. formed by the side shells.
  • this boat comprises at least one mast whose foot is mounted on its base with a double articulation allowing its inclination in two planes, respectively, a longitudinal plane and a transverse plane.
  • the latitude of pivoting of the mast backwards is 10 ° with respect to the vertical, while the latitude of pivoting of the mast laterally is 23 ° on either side of the vertical.
  • the double inclination of the mast is adjusted during the navigation period, the mast being inclined on the windward side, this inclination being all the more important as the force of the wind increases.
  • This arrangement makes it possible to obtain a lifting effect of the sail which will promote the lightening of the hulls, to lower the center of thrust, making it possible to reduce the risks of capsizing and to delay the reduction of sail.
  • the boat shown in Figures 1 to 4, comprises four hulls, namely two side hulls 2 and two central hulls 3 parallel to each other.
  • the two central hulls 3 have a length less than that of the lateral hulls 2 , the rear ends of the four hulls being situated in the same plane and the front ends of the central hulls being situated behind the front ends of the side shells.
  • the four shells are assembled by a number of crosspieces or link arms 4 , the two of which are located furthest forward are shown in the drawing.
  • the four hulls are fitted, at their rear end, with a rudder 5 , each rudder being of reduced dimensions taking into account the fact that the directional force is distributed over four elements.
  • the two central hulls 3 are joined by a nacelle 6 disposed above the waterline, while each central hull 3 is connected to a lateral hull 2 by a nacelle 7 also located above the waterline.
  • the nacelle 6 contains the cockpit 8 and the saloon 9 , while cabins 10 are arranged in the lateral nacelles, with access by the central hulls 3 , the interior of which forms passageways 12 .
  • the link arms between the different hulls are also used for mounting hydrofoil wings 13 .
  • a wing 13 is disposed near the front end of the two central hulls 3 inside the corridor delimited by these, and two hydrofoil wings 13 are arranged in the two corridors delimited by a central hull and a lateral hull, towards the back of the boat.
  • a mast 14 is placed on a connecting arm between the two central shells 3 .
  • This mast is mounted on its base with a double articulation allowing both its lateral tilting at an angle ⁇ from 0 to 23 ° relative to the vertical, as shown in Figure 3 and a tilting backwards at an angle ⁇ between 0 and 10 ° from the vertical.
  • the mast is inclined to the wind of the boat, the inclination being all the more important as the wind is strong.
  • This boat could be equipped not with a mast, but with two masts arranged in parallel, the bases of which would be located at the places shown in dotted lines in FIG. 2.
  • FIGS 5 and 6 show an alternative embodiment of this boat, which is constituted not by a sailboat, but by a motor boat intended for the transport of passengers.
  • this boat in which the same elements are designated by the same references as in the previous embodiment, the central hulls 3 are shorter than the side hulls 2 .
  • the boats described above could have a different structure, the central hulls being longer than the side hulls, or these boats could be used for other uses, such as fishing, for example, without that we go out within the scope of the invention.
