The present invention relates to a method and apparatus for increasing the speed of a cargo ship, a passenger ship, a container ship, an LNG carrier, and other large-scale oil tanker ships of several hundreds of tons to tens of thousands of tons, The structure of the two types of high-speed propulsion units, "automatic variable high-performance crown / double gill box daisy pedal propulsion unit", is synthesized into one, and the structure of the newly developed propulsion unit It is an automatic variable headpick gill box daisy pedal propeller (14) for powerful ship propulsion. It is characterized by a large volume of water inside the vaginal gill box (36) , The effect of which is to produce high value-added large and small vessels, reduce fuel costs and reduce logistics costs, With the revitalization of the system, it will be possible to create new jobs for the mass unemployed people in the IMF era, to regain economic power, and to enter the economic powerhouse in the advanced ranks of advanced countries in the 21st century.
