The results of an extensive experimental program to study the roll damping characteristics of a warship model are reported. The simple free decay curves obtained for a towed as well as a self-propelled nine metre model, fitted with and without bilge keels, rudder and propellers, were analyzed using an energy approach. A new nondimensionalization scheme is used for the representation of the results and used to derive relationships relating the damping coefficient to the value of the metacentric height of the model. The nonlinearity of the damping with forward speed is explained.
