ABSTRACT:
A small watercraft has a hull formed such that the center of buoyancy is slightly aft of the structural center measured in the longitudinal direction of the hull. The craft is equipped with an engine mounted near the center of buoyancy within the hull, and has such auxiliary parts as an oil tank and a muffler which are arranged around the engine. The upper portion of the wall surrounding the engine compartment for the engine may be constructed to protrude upwardly, and a hood with a seat may be mounted over the compartment opening such that the hood can be removed. The joint between the bottom edge of the hood and the upper edge of the surrounding wall of the engine compartment may be located above the draft line of the hull when it is stationary and occupied by the rated number of persons. The fore portion within the hull may be formed into an equipment compartment and a fuel tank compartment, and a hatch cover may be installed over the opening of the equipment compartment so that the cover can be opened and closed by pivoting. The muffler for the engine may be a water muffler through which exhaust gas passes accompanied by engine cooling water, with the fuel tank mounted on the water muffler.
