On Aomori-Hakodate sea line wind is very strong in winter and train ferries often suffer from unfavourable effect of wind on their manoeuvering. To investigate the wind effect on ferries contributing to putting out plans for the reconstruction or for the new design of them, wind-tunnel experiments were carried out on some typical types of them. Changing the direction of wind relative to ship-model in whole range, wind forces and moments acting on ship body above water line were measured. The results of experiments are somewhat different from what are believed generally.
