Definitions

  • a multihull watercraft for example a catamaran
  • a multihull watercraft comprising two or more hulls assembled together by means of a number of mutually independent hollow cross brackets, each hull comprising at least one "bow" hollow module and one "stern” hollow module and, normally, one or more intermediate hollow modules which make it possible to increase the length of the hull itself in a modular manner.
  • the hollow modules are floating ones, are supplied fully equipped, and can be assembled also in water at the place of use through reversible connection means (for example, bolts) operated from the inside of the modules without the need for a boatyard, slipway, particular equipment, and/or specialised staff.
  • reversible connection means for example, bolts
  • the modules and the brackets have dimensions such as to enable them to be transported in containers.
  • Watercraft suitable for transporting heavy means are normally built in boatyards (even though, frequently at a handicrafts level) and are not able to overcome natural obstacles (waterfalls, non-navigable stretches of rivers, etc.), which considerably limit their range.
  • the modular watercraft which is the subject of the present invention enables the above-mentioned limits and problems to be overcome, because the modules that make it up are of reduced dimensions, are supplied fully equipped, are floating, and may be assembled also in the water, without the need for boatyards, slipways, particular equipment (cranes, winches and/or other means of hoisting, welding machines, etc.), and/or specialised staff.
  • a sectional modular multihull water craft according to the preamble of claim 1 is known From US-A-3 883 909. Further it is known from US-A-4 478 167 or US-A-3 965 513 to assemble hollow sections of a boat structure by reversible connection means operated from the inside of the hollow modules.
  • the modules are supplied fully equipped; the modules and the brackets have dimensions such as to enable them to be transported in containers.
  • Figure 1 is a schematic representation of an exploded view of a multihull watercraft (a catamaran) built according to the invention.
  • Figure 1 shows the two hulls 1 (better described with reference to Figure 2), each of which comprises a number of floating hollow modules 2, assembled through reversible connection means 3 positioned inside the hollow modules 2 and operated from the inside of the hollow modules 2 ( Figure 7).
  • the hulls 1 are assembled together by means of hollow cross brackets 5 (as will be more fully described with reference to Figure 6), the number of which and the section of which depend on the amount and nature of the stresses that are expected to have to be withstood by the hollow brackets 5.
  • each of the hulls 1 comprises three hollow modules 2 and two hollow brackets 5, which are independent each other.
  • the multihull watercraft according to the invention is completed with the application on the brackets 5 (in a manner of itself known), of limber boards and/or possible superstructures, which are not illustrated herein because they are extraneous to the present invention.
  • Figure 2 is a schematic representation of a hull 1 belonging to the multihull watercraft of Figure 1, comprising three hollow modules 2 assembled via reversible connection means 3, not explicitly indicated in Figure 2.
  • a preferred embodiment of the reversible connection means 3 will be illustrated with reference to Figure 7.
  • centring couplings of the male-female type located between two adjacent modules 2.
  • the hull 1 of Figure 2 comprises a "stem” hollow module (2A), an intermediate hollow module (2B) and a “bow” hollow module (2C), but without departing from the scope of the invention, the hull 1 may comprise only one "bow” hollow module (2C) and one "stern” hollow module (2A), or else two or more intermediate hollow modules (2B), which make it possible to increase, in a modular way, the total length of the hull 1.
  • the number of intermediate hollow modules (2B) used each time depends on the specific requirements of the user, taking into account that, to be easily transportable (preferably in a container), it is necessary (or, at least, very desirable) that the length of one hollow module 2 built according to the invention should not exceed approximately 12 metres.
  • the "bow” (2C), “stern” (2A) and intermediate (2B) hollow modules differ from one another exclusively in their outer shape.
  • All hollow modules 2 are suitable for floating because they are closed at one end at least by the water-tight bulkhead 4 illustrated in Figure 3 (the intermediate hollow modules 2B present a bulkhead 4 at both ends). Consequently, the hollow modules 2 may be "launched” at the place of use and assembled also in water via reversible connection means 3 (preferably, but not necessarily, bolts that engage in nuts, or else threaded bushings fastened to the bulkheads 4 - Figure 7), without the need for a boatyard and/or slipway.
  • reversible connection means 3 preferably, but not necessarily, bolts that engage in nuts, or else threaded bushings fastened to the bulkheads 4 - Figure 7
  • All the modules 2 are supplied fully equipped (standard or according to the particular requirements of the user), thus simplifying and cutting down to the minimum the operations involved in building an efficient watercraft, without requiring the use of a crane, winches and/or other means of hoisting, or specialised staff.
  • a "bow" module (2A) may come already equipped with an engine, tail-shaft, solepieces and pintles for the rudder, driving cables for the engine and rudder, etc.; in an intermediate module (2B) and/or in a "bow” module (2A), tanks may be installed for fuel or water, or else in these modules a stowaway may be made (for provisions, implements, etc.), and so on.
  • all the modules 2 and the brackets 5 used for assembling together two hulls 1 are of dimensions compatible with transport by lorry, preferably in a 40-ft standard container, which considerably facilitates transportation to the place of assembly of the various modules 2 and brackets 5 making up the watercraft to be built.
  • the dimensions of a module 2 and a bracket 5 do not exceed approximately 2.5 x 2.5 x 12 metres.
  • a further advantageous characteristic of a watercraft according to the invention is represented in the fact that all the hollow elements (modules 2 and brackets 5) that make it up consist (preferably but not necessarily) of monolithic bodies made of composite material obtained by moulding.
  • Figure 3 is a schematic representation of the bulkhead 4 of one of the hollow modules 2 of Figure 2.
  • Figure 3 shows a number of holes 6 made along the perimeter of the bulkhead 4 (in this figure only one of such holes is identified, with the reference “6") suitable for accepting the reversible connection means 3 (Figure 7), a set of holes 7 located along the top edges of the module 2 (in Figure 3, only one of these holes is identified, with the reference “7"), in which are engaged bolts (or other functionally equivalent means of connection) which connect the module 2 to at least one of the brackets 5 ( Figure 6), and the male element 9 of the centring coupling of the male-female type ( Figure 2), located on the bulkhead 4, which engages in a corresponding female element 9' having a complementary shape, located on the bulkhead 4 of the adjacent hollow module 2.
  • the centring coupling (9, 9') enables easy alignment and proper reciprocal positioning of two hollow modules 2 to be assembled and, for this purpose, the surfaces of its elements (male and female) are inclined with respect to the perpendicular to the corresponding bulkhead 4.
  • the male element 9 absorbs at least part of the torsional stresses that, in operation, occur between two assembled modules 2, thus reducing the shearing stresses to which the means of reversible connection 3 are subjected.
  • the angle of inclination of the surfaces of the elements (9, 9') of the centring coupling is preferably, but not necessarily, between 5° and 40°.
  • a threaded pin 16 integral with the male element 9 of the centring coupling is a threaded pin 16, which is inserted in a hole 17 present in the corresponding female element 9' of the centring coupling and "pulled” by means of a threaded handwheel 18 (or other functionally equivalent means of tightening) acting on the threaded pin 17, assembling together the male and female elements (9 , 9') of the centring coupling.
  • Figure 5 is a schematic representation of a top view of two hollow modules 2.
  • the male element 9 of the centring coupling and, in see-through view, the corresponding female element 9' are present.
  • Figure 6 is a schematic representation of two hollow modules 2, each of which belonging to one hull 1, assembled together by means of a cross hollow bracket 5 connected in a reversible manner to the hollow modules 2 by means of bolts (or other functionally equivalent means), which are not explicitly indicated in Figure 6 for reasons of simplicity of graphical representation, inserted in the holes located along the bottom edges of the bracket 5 and in corresponding holes 7 located along the top edges of the hollow module 2, where they are fastened in a manner of itself known, for example, by means of nuts embedded in the top edges of the modules 2 at the holes 7, or else located inside the modules 2 at the holes 7.
  • Figure 7 is a schematic sectional view of a portion of two adjacent hollow modules 2, assembled according to a preferred embodiment of the reversible connection means 3, which makes it possible to assemble conveniently the hollow modules 2, at the same time guaranteeing water-tightness of the modules themselves up to the moment of assembly.
  • the reversible connection means 3 comprise, in combination, a smooth bushing 10 fixed to the bulkhead 4 of a module 2 at one of the holes 6 and closed by a first seal element 11; a threaded body 12 (consisting, for example, of a threaded bushing) fixed to the bulkhead 4 of the other module 2 at one of the holes 6 and closed by a second seal element 13; and one bolt 14, which, at the moment of assembly of the modules 2, is inserted in the smooth bushing 10 and screwed into the threaded body 12.
  • the holes 6 are occluded by the seal elements (11, 13), which prevent water from penetrating inside the hollow modules 2.
  • the bolt 14 is inserted in the bushing 10, an axial pressure is exerted on the bolt 14 to eject the seal element 11 from the bushing 10 and to bring the thread of the bolt 14 to engage with the thread of the threaded body 12, and the bolt 14 is screwed into the threaded body 12 until it is fully tightened; the two hollow modules 2 are thus assembled.
  • the threaded body 12 may consist of a second smooth bushing fixed to the bulkhead 4 at one of the through holes 6 and closed by the second seal element 13 and by a threaded nut.
  • FIG 7 there is also visible a seal 15 inserted (preferably but not necessarily) into a groove made in the bulkhead 4 of at least one of the modules 2.
  • the seal 15 and the corresponding groove are not indicated in Figures 3 and 4 for reasons of simplicity of graphical representation and may be omitted without departing from the scope of the invention.
