The invention relates to the technical field of drag reduction and efficiency improvement of ships and underwater vehicles, in particular to a drag reduction device suitable for a catamaran, the catamaran and a drag reduction method. The air supply unit is used for supplying air to the ventilation cabin through the air supply unit; the ventilation cabin is used for deflating outwards through each deflation hole; wherein the vent holes are distributed in the outer wall of the catamaran and can make contact with water. According to the drag reduction device suitable for the catamaran, the catamaran and the drag reduction method, water resistance borne by the catamaran in the sailing process can be reduced, the sailing speed of the catamaran is effectively increased, and the drag reduction device is simple in structure and easy to assemble.
