In this work a multi-objective optimization procedure for resistance based on a free surface RANSE code is presented. This procedure is made practical by the use of a specific hull shape modeler and numerical restart methods, the effectiveness of the procedure has been demonstrated on an example supported by model test results.

Same procedure is applied to the optimization of hull forms with constraints on stability criterions or for other objectives such as sea keeping. Nevertheless, results will always depend on the solvers used, and allowed deformation.
