This work contains the basic hypothesis used for developing a computer system able to synthesize and optimize a ship's hull structure. The system is composed by a finite element module, a graphic display module, a user friendly data entry and management module and an optimization module. It can be used for hull synthesis or analysis of ships designed on a rational basis. The finite element module is used to calculate the transverse structure and the primary shear stress. The graphic display module can plot model characteristics such as mesh, loads, boundary conditions, as well as results such as deformed shape, stress and force diagrams. The optimization module can handle discrete and continuous design variables and is responsible for the structural synthesis. The program was used to synthesize a hull mid section of a patrol boat that was formerly designed on a trial and error analysis spiral. The results are quite similar but with one significant difference: the time required by the synthesis system, a few hours, is much less than the days spent using conventional procedures.
