The inner frame member has an engine mount portion that supports an engine thereon, an impeller shaft support region that supports thereon an impeller shaft of a propulsion device driven by the engine, and bulkheads extending in the lateral direction of the hull and joined to the inner surface of the hull. In accordance with the present invention, the personal watercraft is light weight, but also retains rigidity and assembling efficiency of the hull.
