The identifiability problem of hydrodynamic coefficients in a nonlinear ship maneuvering model is presented. The contribution plot of hydrodynamic coefficients is analyzed to show the cancellation effect. Slender-body theory is applied to show that the cancellation effect is inherent for the steering dynamics of ships. Parameter transformation is introduced to overcome the difficulty in the coefficient estimation of linear terms. A practical approach is suggested to identify the nonlinear dynamics of ships.
