In very first stage of hull structural design and planning, only limited ship characteristic information, such as C_b, l_<cb> and principal dimensions is available. However, even in that stage of hull design, the factors of external force and moment, in still water and in waves, are significant keys to evaluation of structural strength and hull weight eatimation. A ship builder who specialized in certain types of ships will, of course, adopt a limited range of hull forms. With this reality in mind, we present herein a method of mathematically expressing hull form modifications using previously given basic data such as C_b, l_<cb>, etc. The hull forms produced by this mathematical method show good agreement with those of a limited range of hull forms adopted by a specialized ship builder. Using this method, the results of calculations for still water bending moment and shearing gorce (for a mathemetically described hull form) will be in accord with results derived via previously established conventional methods.
