A personal watercraft includes a ship body, a luggage compartment provided in the ship body and provided with an opening for taking in and out luggage, a hatch attached to the ship body and capable of opening and closing the opening, and a lock mechanism for fixing the hatch to the ship body in a state where the opening is closed. The lock mechanism includes a plurality of lock portions that engage the hatch and the ship body with each other, one operation lever that causes the plurality of lock portions to unlock the engagement in an interlocking manner, and a transmission member that transmits an operation action of the operation lever to at least one of the plurality of lock portions to unlock the engagement of the lock portion.

A personal watercraft propelled by a jet stream includes a boat body, a jet pump, a tunnel, a tunnel opening and a thrust propulsion device. The jet pump includes an impeller disposed at a rear portion of the boat body and generates a propulsive force, and an impeller shaft that rotates the impeller. The tunnel extends in the boat body. The tunnel opening is located at one end of the tunnel, disposed in front of the jet pump, directed in a thrust direction, and opened in the boat body at a position equal to or lower than a virtual plane extending in a horizontal direction along a rotation axis of the impeller. The thrust propulsion device generates a propulsive force in the thrust direction by causing a fluid to flow from an inside of the tunnel to an outside of the boat body through the tunnel opening.
