PURPOSE: A method for building a vessel is provided to reduce the distance between a main hull and a ground surface, thereby reducing accidents by reducing the risk of transmission to the main hull. CONSTITUTION: A method for building a vessel includes the following steps of: preparing a first block forming a part of a hull (S110); connecting a sonar covered with a sonar dome to the lower part of the first block (S120); connecting the sonar dome on the lower part of the first block (S130); and connecting a second block to the lateral part of the first block in which the sonar dome is connected (S140). [Reference numerals] (S110) Preparing a first block forming a part of a hull; (S120) Connecting a sonar to the lower part of the first block; (S130) Connecting the sonar dome on the lower part of the first block; (S140) Connecting a second block to the lateral part of the first block in which the sonar dome is connected
