Abstract : Unified slender-body theory has been applied to predicting the motion of small-waterplane-area twin-hull high-speed (SWATH) ships in head seas. Using this theory, numerical results indicate an improvement in accurately predicting the effects of added-mass and damping coefficients when compared with strip theory. However, the same improvement is not achieved in predicting the effects of exciting forces and motions.
