Abstract
A pneumatic boat comprising a generally U-shaped float open towards the rear and made up of at least one pneumatically inflatable tube, the rear ends of which are braced by a rear board, a rigid floor disposed at least transversely inside the float and a hull with a V-shaped cross section formed by a flexible canvas fixed to the float and to the rear board and held taut by a longitudinal inflatable keel inserted between said floor and said canvas; the inflatable keel is formed by an elongate enclosure delimited by two substantially flat and approximately parallel main walls extending longitudinally and approximately perpendicular to the floor, these walls being braced by a plurality of flexible links; and this enclosure is inflated to a relatively high pressure.
