This paper presents a method of hull form optimization using the computed wave pattern which is obtained by the Panel Shift Rankine Source Method. The principle of the present method is based on the cancellation of free-waves by a superposition of waves generated by a given basic hull and an added thin ship. The main purpose of this method is to find a thin ship which reduce the wave-making resistance of a given hull. The optimization procedure is as follows. At first, the wave amplitude functions of the basic ship are estimated by the computed wave profiles. Then the thin ship form with wave amplitude functions to reduce the wave-making resistance is estimated. At last, the wave-making resistance of the new ship is checked again by the Panel Shift Rankine Source Method. As the examples of optimization, Series60 and SR138 hull forms are chosen and these hull forms are optimized by present method. It is concluded that the present method is useful for design of a ship form with small wave-making resistance.
