RIGID HULL INFLATABLE BOAT IMPROVED CONSTRUCTION ABSTRACT A rigid inflatable boat is provided having multiple inflatable bladders defining a ring around the hull generally at or above the waterline with the inflatable bladders connected to the hull and to each other in a manner facilitating rapid mounting and demounting, and easy repair, thereof. A positioning structure, such as a through-extending hole is formed in the hull for positioning each bladder with respect to the hull, and a holding structure, such as a separate inflatable portion of the bladder, or a rigid flange or a strap is associated with each bladder to cooperate with the positioning structure to releasably hold each bladder to the hull at the positioning structure when the bladder is inflated, while allowing ready demounting when the bladder is deflated. The bladders may be provided with interlocking end structures to stabilize the positions of the bladders with respect to each other, and the hull. A shroud or shrouds may also surround the bladders. A shroud or enclosure generally at and above the waterline comprises a fabric portion of the hull and receives the bladders and is affixed to the major, rigid, portion of the hull.
