Theoretical and experimental clarification of efficacy of reducing pitching when anti-pitching fin is so remodeled that it may be operated by automatic controls; it is expected from calculation that maximum pitch amplitude of ship with controlled fins as used in this experiment is about 75% lower than ship without fin under best condition; on other hand, results of experiment showed also that effect of pitching reduction was great, as indicated by values of more than 80%.
