By analysing the nonlinear differential equation for ship rolling motion, the geometrical figure of Poincare mapping obtained shows a polygon and it's number of side has the relation to the ratio between the period of input force and Strobe period. Then, the geometrical figures of Poincare mapping are given for the period of input force calculated from the ratio as the parameter, systematically. Using Poincare mapping obtained from the experimental data in wind waves and parameters deduced from input force period in power spectrum of pitching motion, the similarity of rolling motions for the mathematical model and experimental ship model has been discussed on the geometrical figure of each Poincare mapping.
