POWER PREDICTION OF FULL SCALE SWATH SHIPS

A computational tool to estimate the power of the full scale SWATH ship is described and compared with the full scale test results of two SWATH ships, showing an excellent correlation between the two results. The tool is used to find an optimum SWATH configuration with regard to resistance at higher speeds, showing that the hull forms of the presently existing SWATH ships at seas can be improved to achieve speeds higher than the present levels by one to two knots or more with little cost of seakeeping performance. The resistance characteristics of a twin strut SWATH model and a single strut SWATH model with regard to resistance are also assessed.
