Abstract:

A mathematical model for predicting the motions of SWATH ships in waves in the frequency domain is presented. This mathematical model requires definition of only geometric and mass properties. While the mathematical model for the vertical plane presented here differs little from the one which has been used for about a decade, the transverse plane model differs from the previous model in various ways. Predictions are compared to measured model experimental responses to regular waves. These results show that the responses to regular waves are well-predicted for a range of hull forms and conditions.
