The invention relates to a multifunctional ship speed controlling fin which is composed of two fin blades, a fin blade intermediate shaft and a connecting shaft, wherein each fin blade is square, and the two fin blades are connected through the fin blade intermediate shaft and can be rotationally folded round the fin blade intermediate shaft; one end of the connecting shaft is connected with the speed controlling fin, and the other end of the connecting shaft is nested on a hull and can rotate back and forth. The speed controlling fin can rotate back and forth on the length direction of a ship through the connecting shaft and can be closely fitted with the hull after being rotationally folded, and the storage of the speed controlling fin is convenient. The multifunctional ship speed controlling fin is a brand-new ship component, is simple in structure and practical and convenient, can effectively improve the course control and deceleration performances of the ship, can be used for ship braking and emergent collision avoidance among the ships, and has a very important significance on ship transportation safety and ship manoeuvrability.
