SWATH Dynamic Simulation Model.

Abstract

A five degree of freedom (constant pitch) simulation model for a Small Waterplane Area Twin Hull (SWATH) ship has been developed. Complete descriptions of the mathematical models employed and a description of the corresponding digital simulation program are presented in this report. Performance predictions based on the mathematical model are also included. The mathematical models are based primarily on experimental model test data measured at the rotating arm facility at the David W. Taylor Naval Ship Research and Development Center (DTNSRDC). The performance predictions generated in this study are appropriate for carrying out rudder configuration design evaluations. The results indicate that the spade rudder configuration is adequate for meeting turn diameter specifications. (Author)
