[0002] A Chinese invention patent application with application number CN202110995469.3, entitled "A Novel Water Ski," discloses a novel water ski, including a rear ski. The rear ski is shaped like an arc, narrower at the front and wider at the back. A base and a fixing device are mounted on the top wall of the rear ski. The base is located at the rear end of the rear ski, and the fixing device is located in the middle of the rear ski. A wave-breaking head is mounted on the front end of the rear ski, and the direction of the wave-breaking head is perpendicular to the direction of the rear ski. A limiting mechanism that mutually restricts the wave-breaking head is formed on the top wall of the rear ski. A storage groove is formed on the bottom wall of the rear ski, located in the rear half of the bottom wall of the rear ski. A tail fin is mounted in the storage groove, and a movable mechanism is mounted in the tail fin. A storage mechanism is formed inside the rear ski, and the storage mechanism is on the same axis as the storage groove. The storage mechanism is used to store the tail fin. The water ski in this invention not only maintains the strength of the rear ski while being relatively lightweight, but also features a tail fin that retracts into a storage slot upon impact with a rock, protecting the tail fin's safety. However, the tail fin structure of this water ski is still relatively simple and does not effectively attract children, resulting in only average entertainment value. Therefore, the structure of this water ski needs further improvement. Summary of the Invention
