Abstract: An inflatable boat (1) comprising laterally two inflatable buoyancy fenders (2) connected by a bottom (13) rigid at least transversely and by an underlying hull (4) presenting an approximately V transverse section, characterised in that a flexible bottom (16), lining the rigid bottom (3) and underlying it, is fixed in a sealed way to the fenders (2) and in that the aforementioned hull (4) is rigid at least in a central longitudinal strip (6) in the shape of a V gutter and is constituted by several sections (11) assembled longitudinally end to end in a removable way and held with the help of removable fixing means (8).

Abstract: Inflatable small craft including at least one inflatable tube (1) forming two substantially parallel branches (2) meeting towards the front to form a stem (3), a bottom sheet (5) forming a V-shaped hull held taut by a longitudinal keel (6) which is interposed between a bottom (4) which is rigid in the transverse direction held along the two aforementioned branches (2) and the bottom sheet (5) which is connected to the tube (1) along the peripheral edges of the bottom (4). The craft additionally includes two auxiliary floats (7) running under the bottom (4) substantially parallel to the respective branches (2) while being offset towards the center with respect to these branches. The auxiliary floats extend close to the branches while being physically separate from them.
