A Full-scale experiment for investigating an effect of Anti-Rolling Board (A.R.B.) equipped with a 35-meter patrol boat was carried out at offshore of Jyogashima Miura peninsula. According to crews' observation, wave height was about 0.5m during the experiment. Since main duty of this ship is watching coastwise routes, this A.R.B. is equipped for the purpose of decreasing roll motion when her speed is approximately zero knot. While the effectiveness of this A.R.B. has been experienced by her crews, the objective of this full-scale experiment, evaluating its effect quantitatively, was achieved by analyzing the data of pitching, rolling, relative wave at bow and vertical acceleration at bow. In fact, it was revealed by analyzing the data of this experiment that roll amplitude in roll natural frequency region is decreased by about 50 percent and that standard deviation of roll motion at sea is decreased by about 24 percent by A.R.B..
