There have been ever increasing demands for estimation and evaluation of manoeuvrability of ships in early stage of ship form design. For this purpose, investigations were made on a practical method by use of PMM tests and theoretical background. In PMM test results, the dependence is recognized of manoeuvring derivatives on the velocity amplitude ; and therefore much inconvenience has been experienced in the application of those derivatives for manoeuvring predictions. To overcome such inconvenience, a practical method is presented, in which analysis is made for damping force components derived from total hydrodynamic reactions by subtraction of inertia forces. By use of the PMM test results obtained through the method, and with the help of theoretical approach, rudder area- and scale-effects are investigated. On the scale-effect especially, the use of wake correlation factor is examined and utility of the method is shown.
