In the previous paper, we reported on a method of determining the derivatives corresponding to a single set of experimentally recorded turning trial data by means of a procedure of successive approximation calculated in two series, i.e. transitionary and stationary states of motion. Nevertheless, we could not see the work which dealt with the different ship's movements. This paper concerns a method of determining the derivatives agreeing to the other turning trial data of the same ship, i.e. to those by other rudder angles. For this purpose, we have varied successively the derivatives, C_<NHβ> and C_<NHγ> which are consistent with γ_s, U_s and ψ_<20> as shown in Fig. 5, and by the use of them, we can fix the value of K_1/K_2 consistent with another data recorded. In conclusion, we present some considerations on this method mentioned above.
