Present stale of mathematical description of ship dynamic non-linear behaviour is preŹsented in this paper with a view to avoiding excessive complications in solving the proŹblem. The non-linearity concerns first of all Froude-Krilov forces and damping forces occurring after entering ship's deck into water or those resulting from drag of bilge keels. And, to the remaining, accompanying and diffraction forces the linear extrapolation has been applied.
