For high speed craft, seakeeping quality is most important with propulsive performance, however, in the initial designing stage, main particulars, hull forms etc. are generally decided from view point of propulsive performance only. Under this circumstance, in this paper, a new method of initial design for high speed craft based on seakeeping quality are proposed and procedure in developing the new method are explaind as follows. First, theoretical calculations were made for nine (9) kind of hull forms to estimate their seakeeping quality. Next, tank tests were carried out in series with four (4) small models to confirm results of above calculations and additional tank test were carried out with two (2) large models to compare round bilge type with hard chine type hull form. In above results, relationsphip between ship length and bow acceleration by ship motion in waves were definitely shown, therefore, in intial designing stage, main particulars are suitably decided for bow acceleration limited from view point of seakeeping quality.
