... A series of tow tank tests were performed to determine whether the added mass moment of inertia in roll and damping roll coefficient for a planing hull are frequency dependent. The model was forced in roll while running at planing speeds. The model was free to heave and pitch, but restrained...

... developed method of analysis which enabled the authors to obtain the non- dimensional damping coefficient from the complete roll decay curve taken over just one full cycle. This method of analysis is based on an energy approach and is explained in [l]. Using this approach, the roll damping moment dependence...
