THE STILL-WATER RESISTANCE AND POWERING CHARACTERISTICS OF SMALL WATERPLANE-AREA TWIN-HULLED (SWATH) SHIPS

This paper presents the results of towing-tank experiments carried out on models of Small Waterplane-Area Twin-Hull (SWATH) ships. The experimental data consist of the resistance and propulsion characteristics. A theory to predict the wave resistance of the SWATH ships has been developed. The results of theoretical predictions and their comparison with the corresponding residuary resistance data also are presented. The generally good agreement between the experimental data and the theoretical predictions indicates that the theory may be used as a reliable tool to predict the resistance characteristics of the SWATH ships.
