Abstract: Rigid thermally insulating panel (1) which consists of at least two flexible composite sheets (2) spaced apart by a great number of flexible strands (3) arranged so that in the inflated state the two composite sheets (2) are held apart and in predetermined positions one with respect to the other, each composite sheet (2) comprising, from the center toward the outside: a protective internal sheet (4), transparent to electromagnetic waves, a thin sheet (5) of a metal reflecting electromagnetic waves, a layer (6) for protecting the metal sheet, a fibrous layer (7) providing the sheet with mechanical strength, a layer (8) of a coating polymer providing proofing, a layer (9) for protecting an underlying metal sheet, a thin sheet (10) of a metal reflecting electromagnetic waves, and a protective outer layer (11) transparent to electromagnetic waves.

Abstract: Inflatable small craft including at least one inflatable tube (1) forming two substantially parallel branches (2) meeting towards the front to form a stem (3), a bottom sheet (5) forming a V-shaped hull held taut by a longitudinal keel (6) which is interposed between a bottom (4) which is rigid in the transverse direction held along the two aforementioned branches (2) and the bottom sheet (5) which is connected to the tube (1) along the peripheral edges of the bottom (4). The craft additionally includes two auxiliary floats (7) running under the bottom (4) substantially parallel to the respective branches (2) while being offset towards the center with respect to these branches. The auxiliary floats extend close to the branches while being physically separate from them.

Abstract: A device (1) for survival at sea, comprising a pneumatic raft (2) or the like in the uninflated and folded state, together with at least one reservoir (3) of inflation fluid, which raft and reservoir are enclosed in a rigid container (4), the device being characterized in that the container (4) includes a hatch (9), and in that the reservoir of inflation fluid (3) is provided with at least one sensor (10) for detecting at least one magnitude characteristic of the state of the fluid contained in the reservoir, in particular its pressure and/or its temperature, and is organized in such a manner that said detected magnitude can be measured through the open hatch of the container, thereby enabling the state of the survival device to be inspected without opening the container.

Abstract: An inflatable boat (1) includes at least one inflatable buoyancy tube (2) forming two substantially parallel branches (3) that are united towards the forward end (4). A bottom (5) that is rigid in the transverse direction is held between the two branches (3) of the inflatable tube (2). A transom (6) is provided for supporting an outboard motor assembly. The boat is characterized in that the stern portion of the underside of its bottom (5) supports at least one projecting bulb (7) that is elongate in the longitudinal direction of the boat and that is constituted by a flexible bag which is inflated by a fluid under pressure. This bulb (4) is disposed facing the position occupied by an arm of the motor assembly that plunges into the water and that supports at least one thrust member together with anticavitation plates.

Abstract: The seat system comprises:two housings (7) including respective grooves (9) and secured to said base, the housings extending approximately parallel to each other;at least two legs (11) each including an elongate shank (15) terminated at each of its two ends by respective angled projections (15, 17), the bottom end ones of said projections (17) of the legs being inserted in the grooves (9) of respective ones of the housings (7) and being retained therein in such a manner that the shanks are upstanding while sloping relative to the vertical;a device (20) for locking the legs axially in their respective housings;a seat proper (10) suitable for standing on the angled projections at the top ends of the shanks (15); anda quick-fastening device for fastening the seat proper to the top angled projections of said shanks.

Abstract: An inflatable pneumatic boat with a non-flat rear board.An inflatable pneumatic boat comprising a rear board (5) extending transversely and approximately vertically between two lateral floats (2), characterized in that the rear board (5) is a non-flat one-piece component and has two lateral panels (6), each connected to a float (2), and a central panel (7) offset to the rear beyond the rear edge of the bottom (4) of the boat.

Abstract: A boat is disclosed including a composite hull with a rigid bottom (2) and an inflatable tubular buoyancy element (3) having a general U shape fixed to the upper edge of the bottom along the front and lateral sides thereof, the bottom having at the rear an upstanding wall forming an upper stern (4), a rigid deck (5) being further fixed to the bottom and defining therewith a housing (6) for an on-board drive and propellant device, in which the deck (5) forms, in its rear half, an upwardly projecting axial T shaped console (9), the transverse bar of the T forming a transverse seat (10) and the leg of the T forming successively (from the rear forwards) a jockey seat (11) for the pilot and a block, which is raised with respect thereto, forming a piloting post (12) situated immediately behind the seat (10), the rear end of the leg of the T being connected to the upper stern (4); the portion of the deck situated on each side of the jockey seat forms a floor (13) for the pilot; and the drive and propellant device ar

Abstract: The craft incorporates a keel (3) essentially constituted by an elongated capacity (4) formed out of a flexible or resilient material which is distortable and watertight. A water inlet opening (6) is provided in the wall of this elongated capacity (4) oriented towards the bow of the craft and maintained in the open condition, in order to have the water back pressure prevailing in this elongated capacity (4) as soon as the craft is moving in the forward direction, said elongated capacity (4) being then at least partially filled with water.
