The hull form optimization has been recognized as one of the most important application fields of wave making resistance theories, and many related research works have been done. In near future, designers will be able to determine the hull form by using the optimization method based on advanced numerical ship hydrodynamics and nonlinear optimization programming techniques. In the present paper, the hull from optimization method based on Rankine source panel method and Sequential Quadratic Programming (SQP) technique is discussed. In the optimization process, the initial hull form can be improved by changing its frame lines and bow stem profies under the prescribed design constraints. Especially, shape optimizations of bow bulbs are shown for non-protruding and protruding bow bulb. As numerical examples, a fishing vessel with non-protruding bulb and the HTC (Hamburg Test Case) container ship with protruding bulb are selected.
