• The bodily sinkage of a ship going in shallow water is analysed by means of the analogy with the transonic aerodynamics. The OGSA method is employed to solve the basic equation in such a way that the nonlinear characteristic is preserved. The numerical work is confined in the subcritical speed range where a continuous solution exists. Three kinds of Wigley's parabolic models with different beam to length ratios are employed for numerical examples. Computed results for the sinkage show fairly good agreement with the measurement in the towing tank, and the feasibility of the method as the practical assessment of the sinkage in shallow water seems to be quite promising.
