Abstract: Disclosed is a vessel with two watertight flaps attached in a tensioned state on the two sides of the longitudinal keel, each being under one of the two rear side portions of the V-shaped hull, the outer side edge of each flap being connected under the shell covering the bottom compartment on the same side, and the bottom side edge being connected to the bottom along a line which is angled from the rear to the front and angled toward the lower compartment, with a flap width tapering from the tensioned, free rear edge between the ends at the transom, toward a front portion connected to the bottom and/or to the shell at the connection between the upper and lower compartments, defining, with the latter and the bottom, a channel converging from front to rear and angled toward the rear end of the edge of the V-shaped craft hull.

Abstract: The invention relates to a vessel which includes two watertight flaps (13) attached in a tensioned state on the two sides of the longitudinal keel (7), each being under one of the two rear side portions of the V-shaped hull, the outer side edge (16) of each flap being connected under the shell (11) covering the bottom compartment (9) on the same side, and the bottom side edge (17) being connected to the bottom (6) along a line which is angled from the rear to the front and angled toward the lower compartment (9), with a flap width that gradually tapers from the tensioned, free rear edge (14) thereof between the ends thereof at the transom (4), toward a front portion connected to the bottom (6) and/or to the shell (11) at the connection between the upper (8) and lower (9) compartments, in order to define, with the latter and the bottom (6), a channel converging from the front to the rear and angled toward the rear end of the edge of the V-shaped hull of the craft.

Abstract: A craft includes a rigid hull (1) that consists of a V-shaped bottom (5) and a bridge (4) on which a load can rest. The hull includes plating consisting of compartmentalized pneumatic floats (2), the rear compartments (32) of which are combined with an inflation and deflation system so as to vary the buoyancy of the craft. The craft also includes a submergible hull (1), the central cavity (9) of which is formed between the bottom (5) and the bridge (4) and is open at the rear so as to be automatically filled or emptied, the central cavity (9) containing at least one bag (10) that is combined with an inflation and deflation system enabling the buoyancy to be varied and consequently the level of immersion of the stern (7) to be changed as needed.

Abstract: A semi-rigid boat, includes a rigid hull (11) provided, at the bridge thereof (6), with two types of holders for the inflatable tube(s): a gutter-shaped holder for receiving, at the bow and/or at the stern, a section (13, 14) of tube (12) having a circular cross-section; and a planking wall-shaped holder (16) that extends between the bow and the stern, which is provided so as to engage with an inflatable section-shaped structure (15) having a D-shaped cross-section that extends longitudinally between the sections (13, 14). The section (15) of inflatable tube having a D-shaped cross-section is attached to the bottom portion and to the top portion of the planking wall (16).

Abstract: An inflatable boat comprising: an inflatable float that is U-shaped and open at the stern, and that braced by a transom; a floor that is disposed inside the space defined by the float, and a V-shaped keel formed of a flexible canvas sheet fastened to the float and to the transom and tensioned by a longitudinal inflatable keel-forming spacer interposed between the floor and the canvas sheet; the inflatable keel-forming spacer is formed by at least two elongate and flat chambers inflated under a relatively high pressure; and the two chambers have their respective bottom longitudinal edges touching and their respective top longitudinal edges spaced apart from each other so that the keel-forming spacer is generally V-shaped in cross-section.
