Abstract: The influence and significance of stiffness properties and shear centre on the dry and wet antisymmetric responses of a containership are examined. The ship travels at 26 knots in regular sinusoidal bow waves of unit amplitude. A comparison is included of response predictions derived from unified and rigid body theories since the latter theory excludes all structural properties such as flexural and torsional rigidity or stiffness, warping etc. The results of the investigation provide an excellent justification for adopting a unified dynamic analysis to a flexible ship structure and illustrate the versatility of the theory.
