  • Detachable inflatable boat bottom
    Patent number: 4858550
    Abstract: A hard shell shaped to intimately cover the bottom of an inflatable raft. The shell is made of various contoured staves or segments joined together. Straps are used to attach the shell to the raft, bow and transom. A combination transom and mounting frame is used in the raft which do not include a built-in transom. The shell not only protects the raft against abrasion and puncture, but also reduces its drag coefficient, contributes to it stability and enhances its directional control.
