the design constraints, hull parameters which influenced the wetted 

 surface most were varied." The optimization of wavemaking resistance 

 and the conputation of total resistance were repeated. After a few 

 such repetitions, a final singularity distribution was chosen. 



The theoretical analysis was performed with the aid of an 

 existing wavemaking reistance computer program. Since the sub- 

 merged main-hull length was different from the strut length, some 

 difficulty was encountered in using this program. For this reason, 

 discrete source points, rather than a continuous line source, were 

 used for a main hull. The final singularity distribution of this design 

 is given as follows.
