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.
