Abstract: Using two-dimensional linearized potential theory, strip theory and a finite element method, mathematical and numerical models are developed for the computation of the hydrodynamic coefficients of a slender ship form, travelling with forward speed in shallow water. The theory is applied to the computation of hydrodynamic mass and damping of a Todd Series 60Cb=0.70 ship model. Both experimental and numerical results are presented as functions of oscillatory frequency, water depth and forward speed.
