ABSTRACT:
In a rigid inflatable boat having a rigid hull with a bottom wall and side walls having top edges carrying floatation pontoon, a water jet drive is mounted on the bottom wall near a transom closing the rear end of the hull. The jet drive has an inlet communicating with a hole through the bottom wall and an outlet communicating with a hole through the transom. A steering cowl arrangement is mounted around the outlet of the jet drive and is connected to a steering wheel and handle for controlling the direction of water discharge for the jet drive. Seals are provided between the floatation pontoons and the transom for avoiding entry of water into the hull. The boat includes a seat positioned forward of the jet drive to distribute weight evenly on the hull.
