A study of the characteristics of manual steering by the student

The purpose of this study is to consider the learning processes of the students, who are undergoing the training of ship handling techniques. Safety at ship handling depends on the skills, which can only be acquired by careful attention to details and by experiences. An investigation was made on manual steering of ship's course keeping. Yaw and rudder angle were measured simultaneously while students, who are on board training, steer the training ship double prime Tenyo-maru double prime (716GT). Also on board experiment were carried out by using double prime Konpeki double prime (12GT). As the results, the response times of the steering correspond to changing the yaw angle were estimated and the differences in ability among students could make clear. The characteristics of these differences could be classified into 4 patterns. These results indicate the possibility put to practicaluse for the training of ship handling techniques.
