Abstract

A personal watercraft can be rotated in a correct direction of rotation when the personal watercraft has been overturned, and can thereby be restored to a normal, upright position. The personal watercraft includes a vessel body, an engine, and an exhaust system. The exhaust system includes a muffler, disposed on a first side of the vessel body, and an exhaust pipe connected to the muffler and formed in an inverted U-shape. During operation of the engine, exhaust gas passes through the inverted-U-shaped exhaust pipe and is subsequently discharged to the outside environment via an exhaust port. The exhaust port is disposed on a second side of the vessel body opposite the first side. The vessel body has a hollow water-receiving portion formed therein, on the second side thereof. The water-receiving portion is adapted to be submerged under water when the personal watercraft is overturned in a body of water.
