Recently, importance of estimating of ship's propulsion performance in basic design stage is increasing because of growing in size, speeding up and diversification of ship. Since small high-speed craft's type of ship and its performance are various, it cannot be said that data which used in designing of small high-speed craft is enough. Authors have carried out towing tank test in still water by 1/16 scale model of small high-speed craft "WAKASUGI" and observed wave collapse phenomenon near the bow to establish the new evaluation technique for design of small high-speed craft. In this paper, the relation between wave collapse phenomenon consist of wave and spray near the bow and measured ship resistance are described. A digital still camera and digital video camera are used to observe the wave collapse phenomenon in the tank test. The resistance coefficient obtained by the tank test is compared with the resistance coefficient obtained from presumptive function.
