An inflatable motor boat refers to water vehicles, in particular, to inflatable boats with outboard engines operating in low water conditions. The problem to which the invention is directed, is to improve the performance parameters of inflatable motor boats. The technical result of the claimed invention is the possibility of high-performance boating in low and extreme low depth conditions at different speeds due to the presence of the inclined longitudinal tunnel, with some configuring details in different versions, which allows to improve the water supply to the propellers of outboard engines or, in the case of water jet engines, to their water jet inlets, to optimize their location and eliminate the risk of damage thereof. The claimed technical result is achieved by the fact that the invention is an inflatable motor boat with a U-shaped hull in plan view. The hull of the inflatable motor boat is formed by open outline of inflatable boards and bow part. An inflatable bottom is attached to the hull, which bottom is divided into at least three longitudinal segments. A longitudinal tunnel is made in the middle segment of the bottom, the inner surface of which tunnel has essentially arc-shaped form. The tunnel comprises a portion having a wedge-shaped form in a vertical section, wherein the angle of inclination of the portion relative to the water surface plane is from 5° to 45°. The tunnel can also comprise an additional portion with an angle of inclination from 0° to 20° relative to the water surface plane, wherein the length of the additional portion is less than the length of the wedge-shaped portion.

    L'invention concerne des structures de canots gonflables comportant des moteurs hors-bord. Le canot comprend un corps en forme de U dans un plan ayant un contour clos des bords gonflables et de la partie nez, un fond gonflable relié au corps et divisé en au moins trois segments longitudinaux. Le segment médian du fond comprend un tunnel longitudinal. Dans une première variante, la surface interne du tunnel longitudinal du canot possède essentiellement une forme d'arc, et le tunnel comprend un segment supplémentaire dans la section verticale en forme de coin avec un angle d'inclinaison par rapport au plan de la surface de l'eau. Dans une deuxième variante, le tunnel longitudinal du canot comprend un segment dans la section verticale en forme de coin. L'extrémité poupe du fond, qui est reliée au tunnel, est inclinée et définit un angle par rapport au plan de la surface de l'eau. Dans une troisième variante, le fond gonflabe du canot comprend, dans le prolongement du tunnel longitudinal, au moins deux canaux de conduction d'eau de profondeur variable. On obtient ainsi une grande efficacité du fonctionnement du canot à des profondeurs faibles ou très faibles et à différentes vitesses.
