ABSTRACT:
A small watercraft including a hull of longitudinally elongated shape having a deck in its upper part, and an engine for thrusting the watercraft forwardly. The hull is formed in the forward and rearward portions of its lower part with water accommodation compartments formed with a plurality of openings for water to flow therethrough into and out of the compartments. When the watercraft is at rest, water flows into the water accommodation compartments through the openings to stabilize the hull. When the watercraft is cruising, the water in the water accommodation compartments is released therefrom through the openings, so that the watercraft lightly cruises.
