This paper analyzes the method of determining the main dimensions and estimating the power of the main engine in the scheme design of fishing boats, and optimizes the general layout of the main deck of fishing boats. Under the condition of known displacement, maximum speed and total length, the main dimension of fishing boat is determined, the main engine power estimation value is derived by the mother ship series fitting method and the Daisumi Mihiro's method, the validity of the estimation result is determined by comparative analysis, combined with ergonomics, the general layout of the main deck of fishing boats was optimized, which increased the radius of the crew's activities and improved the range of activities of the main deck. Through the methods used, the design and optimization scheme of fishing boats are determined, which can accumulate experience for the design of fishing boats in the future.
