Abstract
Abstract A collapsible, inflatable boat is provided having two large inflatable tubes as hulls connected together by a floor raised above the midpoint of the hull tubes and supported by spaced-apart, laterally-extending rigid members flexible connected thereto. An inflatable, semi-tubular chamber is disposed beneath the floor and extends longitudinally of the boat midway between the hull tubes. A hinged, rigid transom is provided at the rear of the boat, and a forward end member closes the front of the boat to permit collapsing of the boat to a relatively small package without having to remove any parts from the boat.
