A personal watercraft comprises a hull assembly and a deck. The hull assembly includes a hull and a liner. The hull has an outer peripheral support portion. The outer peripheral support portion has a first section with a first upper surface and a second section with a second upper surface. The liner has an outer ledge portion adhesively attached to the first upper surface of the first section of the outer peripheral support portion such that the outer ledge portion does not overlap the second upper surface of the second section of the outer peripheral support portion. The deck is provided to the hull assembly in a watertight manner. The first upper surface is located at a height position that is different from a height position of the second upper surface with respect to a vertical direction.
