Description

The hand steering in harbor is probably not substituted for any other instrument for the time being. Then miss-steering is apt to cause a casualty particularly for giantio ship. We obtained the following results by inquiring of many quartermasters about miss-steering: 1) 93% of miss-steerings occur in the case of no gesture in giving order. 2) 68% of miss-steerings occur in the case of right answer back for order. 3) 58% of miss-steerings occur in the "stand-by" situation. 4) 79% of miss-steering in the "stand-by" situation occur within first half an hour of steering watch.
