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.
