A surface ship hull form is used here to validate the model. Five hull form parameters are selected as the de⁃sign variables and different optimization algorithms are used to optimize the hull shape. The optimized pa⁃rameters group is obtained and the best optimization algorithm for the hull form optimization is gained. The parametric hull form optimization approach is approved to be feasible and effective by the example.
