The invention discloses a miniature ship capable of guiding a marine lifesaving ship to sail at night. The miniature ship comprises a hull. Each of the two ends of the hull is provided with two signalreceiving rods, an electric telescopic rod is arranged on the middle portion of the hull, a photosensitive sensor is arranged on the outer wall of the lower portion of the electric telescopic rod, analarm is arranged on the outer wall of the middle portion of the electric telescopic rod, a controller is arranged at the bottom of the photosensitive sensor, a lighting lamp is arranged at the top of the electric telescopic rod, the bottom end of the electric telescopic rod is connected with a rotary rod, and the bottom end of the rotary rod is connected with a motor. The lighting range of the lighting lamp can be changed along with the light intensity of the external environment through the photosensitive sensor and the controller, sailing ship information such as position information and ship route information can be obtained through signal acquisition devices and signal transmitters, so that a ship route of the sailing ship is guided, position information of the miniature ship and thesailing ship can be further accurately shared through ultrasonic detectors and ultrasonic probes, and the miniature ship is prevented from striking a reef or hitting an obstacle through an infrared detector.
