A new methodology for hydrodynamic optimization of a TriSWACH is developed, which considers the shape of the center hull only and its optimal results are not influenced by the position configuration of side hulls. In order to accelerate the process of the optimization, a practical multi-objective hydrodynamic tool has been further developed by integrating a surrogate model to approximate the objective functions and constraints. The proposed method and the further developed tool are applied to optimize the hull form of a TriSWACH with nine possible side hull position configurations for reduced drag. A considerable drag reduction is obtained by the optimal TriSWACH for various side hull configurations and speed range.
