A new pneumatic inflatable-type boat, characterized essentially by comprising an outer, impermeable and flexible envelope made of suitable laminar materials, which is suitably configured to take the form of a boat and which is provided with a central hatch to which contour is joined a pneumatic chamber provided with a valve that allows the entry of air to a sufficient pressure that transmits to said chamber a rigidity by which the dimensional stability of the hatch remains unchanged, distinguishing other valves that belong to a pneumatic frame composed of two tubular chambers that are joined at their ends by biased assemblies that determine acute angles at the stern and bow ends of the boat and the parallelism of said pneumatic chambers and their contact against the interior sides of the enclosure remaining unchanged, thanks to some pads, also pneumatic and provided with the corresponding valves, which are applied at their ends against the coinciding opposite arcs of the aforementioned tubular chambers and at the points of inflection of these where the convergence of the sides coinciding with the vertices of stern and bow.
