A planning boat includes at least one tank provided on a bottom of the boat. The tank has, at a stern side, a wall through which a through hole is provided below a waterline. A hull of the planning boat includes a bottom plate that forms the bottom of the boat, right and left side plates that form sides of the boat and a bow, a transom plate that forms a stern, and a plurality of longitudinal vertical plates. The plurality of longitudinal vertical plates each extend between the transom plate and forward portions of the side plates along a sailing direction and each have a lower surface that is fixed to an upper surface of the bottom plate. The tank is formed by using the pair of longitudinal vertical plates of the existing planning boat.

The present invention relates to a novel apparatus and method for installing split line cutters on marine propeller shafts. The apparatus features a clamshell design comprising an upper and lower half, each with an inner cavity configured to accommodate a portion of the split line cutter. A hinge mechanism connects these halves, facilitating easy opening and closing around the propeller shaft. Key to this invention is a captive screw retaining mechanism within the clamshell, designed to hold screws in place even when unfastened, thereby simplifying the installation process and preventing loss of components. The apparatus includes a screwdriver opening aligned with a bolt cavity, allowing for engagement of captive screws. Additionally, the invention features temporary closure mechanisms, for secure handling during installation, and a retaining hole for attaching a line. This invention offers significant improvements in the installation of line cutters, emphasizing safety, efficiency, and ease of use.
