Three different strut shapes were investigated to determine the effect of shape on the heave motion of SWATH ships at heave resonance. A time-domain analysis was developed to include the nonlinear effect of large motion amplitude. A two-dimensional model, in which the ship forward speed is assumed to be zero, was investigated to simplify the problem. The results show that a proper choice of strut shape can reduce the ship heave motion substantially at resonance.
