It is well-known in slow ship theory that the usual linearized free surface condition cannot be applied when obstacles are considered of which the beam to length ratio is not sufficiently small. Several authors (Baba, Eggers, Hermans, Maruo and Ogilvie) have studied the effect of nonlinear terms in the free surface condition. In principle the local velocity determines a local Green’s function for the calculation of the wave pattern. A different approach is the application of the ray method (Keller).
