• the boat, or boat, shown in plan 1, in the form of a schematic half-view, comprises a rigid shell 1 and an inflatable flange-shaped ply 2, which flange may comprise several inflatable compartments separately.
• This inflatable bead 2 extends between the stern 3 and the bow 4 and its section, along the entire length of the plating, is circular.
• This coil 2 rests on a support 5 in the form of a gutter which runs on the periphery of the rigid shell 1, at the periphery of the bridge 6.
• This support 5 has a section in the form of a circular arc to accommodate a portion of the cylindrical casing of the coil 2 and, in particular, a longitudinal band located at the bottom of said flange.
• the strand 2 comprises, along its length, a rope 7 which engages and cooperates, as shown in Figure 6, with a slide 8 arranged on the outer rim 9 of the rigid shell 1, at the intersection of the rim 9 and the end of the surface of the support 5.

• FIG. 2 shows, in the form of a half-view in plan, the boat according to the invention which comprises a rigid hull 11 and a flange 12 whose section evolves between the bow 3 and the stern 4.
• the flange 12 comprises several sections that form a continuity:
• This section 15 extends over a length that corresponds, for example, to at least half of the total length of the boat and is, for the most part, rather towards the rear, that is to say towards the stern of said boat, in the area of the deck 6 which has seats, for example.
• the section 15 may comprise, at its lower part, as represented in FIG. 7, a rope 17, which rope 17 is situated, for example, in the extension of the ropes 7, similar to those of the boat of FIG. 1, and arranged on the sections 13 and 14, ensuring continuity.

• An embodiment according to Figure 4b to two inflatable tubes 25 and 26 to form section section 15 D-shaped has the advantage of improving the impact resistance and safety of the boat. Indeed, if the outer coil 25 is torn or deflated, accidentally, then there remains the inner coil 26, which continues to provide reduced buoyancy but sufficient to keep the boat afloat.
