An analytical method to predict yawing motion of a ship in oblique seas has been developed. Computations of yawing motion of the Series 60 (Cb = 0.60, L/B = 7.5) have been carried out applying rotating arm data obtained at Tank No. 2 of Davidson Laboratory in 1962, and computed results of virtual mass and damping on ship-like sections by Tasai in 1961. The predicted yaw amplitudes in quartering seas were compared with the experimental results for the same model. Results showed excellent agreement between predictions and experiments throughout the computed range of wave length, ship speed and encounter angle. (Author)
