According to the mother type ship provided ，this ship main elements data of the decision and weight, center of gravity calculation, the layout design, ship shape line design, stability and float state main performance, resistance estimation and propeller design aspects calculate, drawing, checking and meticulous work, and according to the design of ship COMPASS chart using software will ship geometry form of input bond gold curve calculation, static hydraulic calculation and cross into curve calculation, use computation income data and rendering the static hydraulic curve. According to the whole design,I analyzed the new design ships advantages of ship type and the existing deficiencies compared with mother ship. And as far as possible in the ship design satisfied the basic requirements of the main: 1. Suitable, the economy. Improving the ec
