A personal watercraft configured to eject water rearward from a body thereof to generate a propulsive force, includes a pair of right and left resistive elements which are attached to the body and configured to be able to receive water resistance during travel of the watercraft. The resistive elements are configured to move between an operating position and a non-operating position, the water resistance being larger in the operating position than in the non-operating position. Each of the resistive elements includes a pressure receiving section configured to receive the water resistance in the operating position, and wherein in the operating position, at least a portion of the pressure receiving section is located outward relative to a coupling portion where the resistive element is coupled to the body, in a width direction of the body.
