In this work a new optimization procedure aimed at the fore body and bulb shape optimization for the best wave resistance performance of a hull in calm water is presented. A parametric CAD and a CFD solver are linked and driven by an optimization procedure that generates hull shapes and runs a wave resistance code automatically, comparing the results obtained. A special care has been given to the algorithm used for the parametric generation of the fore body hull shape, especially at the bulb tunnel. The test case here presented is related to a cruise ship from Fincantieri Shipyard.
