The air layer resistance reduction device comprises a protruding ship bottom plate component, the protruding ship bottom plate component comprises a box body capable of forming a hollow cavity, the upper surface of the box body is attached to and fixedly connected to the outer surface of a ship bottom plate, the lower surface of the box body is used for making direct contact with water, the box body is provided with an air outlet, and the air outlet is communicated with the hollow cavity. A hollow cavity is formed in the ship bottom plate, a vent hole communicated with the hollow cavity is formed in the ship bottom plate, a plurality of airflow guide plates are arranged in the hollow cavity, and the airflow guide plates are arranged in a radial mode with the air inlet area, in the hollow cavity, of the vent hole as the starting end and the air outlet of the box body as the terminal end. According to the gas layer resistance reduction device, the coverage range of gas sprayed out of the gas outlet is larger than the projection length of the protruding ship bottom plate component on the ship width, the gas coverage range is increased, and the problem that in the prior art, the gas spraying coverage of a gas layer resistance reduction device is not high is solved.
