  • the boat chosen as an example is of the catamaran type and is made up of a V-shaped pneumatic float l forming part of a collapsible structure comprising a forward transversal board 2, a stern transversal board 3, and a longitudinal beam 4.
  • Boards 2 and 3 rest, by means of their suitably-hollowed out ends 5, 6, on the inflated arms of float 1 to which they are fixed, preferably by strops.
  • Boards 2 and 3 are connected by longitudinal beam 4, to which they are'fixed by means of removable joints.
  • the ends of boards 2 and 3 are connected by collapsible longitudinal bars 7 and 8, parallel to beam 4, resting on the floats and serving to hold fast the bracing.
  • the mast 9 is placed in front of board 2, with its base housed in longitudinal beam 4.
  • the forward tip of float 1 is connected to the boat structure by bars 10, 11, 12, positioned in accordance with the edges of a pyramid having its summit fixed on the forward tip of float 1 and its base fixed to the structure.
  • the said pyramid is triangular, lower bar 10 being fixed at 13 to the front of beam 4 and the two upper bars 11 and 12being fixed, at 14 and 15 respectively, on the upper part of forward board 2.
  • the relatively large distance between fixing points l3, l4 and 15 in relation to each other makes the pyramid of bars 10, 11 and 12 and, consequently, the fixing of the forward part of float 1, very rigid.
  • This pyramid of bars also serves to obtain, at 16, a rigid fixing for the forward stay of mast 9.
  • the pyramid of bars 10, ll, 12 may also be used to support a shelter-deck 17 of flexible material fixed, by means of toggles and loops, such as 18, on the forward part of float l and on the forward board 2.
  • the deck 17 is notched at 19 to allow for mast 9.
  • a pyramidshaped bag 20 is fixed to advantage under deck 17, this bag being housed inside the pyramid of bars. Bag 20 opens and closes on a level with deck 17 by means of turned-down pieces 21, 22 fitted with zips 23, 24. This bag 20 serves as a locker for sails or other objects.
  • the boat is fitted with a deck made up of two halfdecks 25, 26, held in position by central beam 4 and forward board 2 and rear board 3.
  • the half-decks may be flat, as illustrated at 25 and 26,. but in accordance with one characteristic of the invention, they may also form a dish 27 whose bottom 28 is on a lower level than the bottom of the beam, this bottom 28 rising towards the front 29.
  • dish'shaped half-decks can, if necessary, provide a certain amount of buoyancy if float 1 should be partially deflated.
  • the strops fixing the structure to the floats pass through bights fixed to the half-decks to ensure that the whole is completely attached.
  • the back of stem board 3 is left clear, to allow for the fixing of an outboard motor in the middle of it.
  • a part 30 is placed at the back of board 3, in the extension of beam 4, centered by pins 31 and held in position by hook-stirrups 32 fitting into the eyes of stay-tighteners 33, whose threaded ends receive nuts 34 resting against the inside wall of board 3.
  • the rudder 35 articulates at 36 on extension piece 30.
  • the central beam also serves as a tail fin support. In preference, this tail fin pivots.
  • the boat in accordance with the invention may have a V-shaped pneumatic float 37 whose inflated arms are very close together, and two lateral pneumatic floats 38 and 39.
  • a boat similar to a trimaran is produced, with one central and two lateral floats.
  • the boat so produced has various advantages over the trimaran, which is supported asymmetrically by its central float and one or other of its lateral floats, and thus always has a list. Thanks to its V- shaped float 37, the boat in accordance with the invention is supported symmetrically, lateral floats 38 and 39 intervening only when the boat has a lateral list, in
  • this arrangement allows the width of the boat to be reduced in relation to the trimaran.
  • the boat structure comprises forward transversal board 40 and stem transversal board 41 connected by three longitudinal beams, central 42 and lateral 43, 44, and two longitudinal bars 45, 46.
  • This structure also comprises decks 47, 48, and beams 49, 50, spreading the load over the inflated arms of float 37 and ensuring fixing of these inflated arms to the structure.
  • the boat comprises a mast 51 and a pyramid of bars 52 similar to that already described.
  • the longitudinal beams and the boards are assembled by means of vertical bolts.
  • Panels 53, 54, form a deck covering the upper part of the float.
  • the boat in accordance with the invention may include a cabin 55 whose dish-shaped planking 56 is positioned between the inflated arms of V- shaped float 57.
  • This arrangement allows the utilizable height of the cabin to be augmented, and increases security, particularly when the boat is overloaded.
  • the structure comprises the forward 58 and stem 59 transversal boards connected by four longitudinal beams 60, 61, 62, 63, arranged in pairs on either side of the inflated arms of float 57.
  • the lateral pneumatic floats 64, 65 are fixed at the ends of boards 58 and 59.
  • the structure is completed by longitudinal bars 66, 67 and by outer planking 68, 69.
  • the boat may be fitted with one or two tripod masts. Pivoting tail fins or drop keels 70,71 are housed in beams 61, 62. Cabin bunks 72, 73 are placed above the inflated arms of the float and distribution beams 74, 75.
  • a four-bar pyramid 76 similar to those already described is positioned at the front of the boat.
  • each lateral float 64, 65 is placed a bench 77, 78 whose hollow, watertight interior forms a ballasttank.
  • ballast-tanks are filled by means ofa pump placed in the cockpit and pipes which also shift ballast from one tank to the other to balance the list. Reservoirs formed by hollow planking 68a, 69a may also be used as ballast-tanks.
  • stiffening bars define a triangular pyramid and comprise one lower bar fixed to said longitudinal beam and two upper bars fixed to said forward transversal board, said longitudinal beam being provided with a drop keel well.
