When a large angle to change course of this type is performed in these waters, as in the case of Vessel A, the bow ofthe give-away vessel ended up pointing in the direction of Tokushima. Naturally, even if she turns towards the asternof the other vessel, the give-way vessel can be manoeuvred in such a way as to follow the astern, making it possibleto return reasonably quickly to her original course. Therefore, the deviation of the give-way vessel from the originalcourse is not that great. However, psychologically, this means heading the vessel straight towards the coast, navigationofficers without much experience and whose technical skills are not sufficient can hesitate to carry out such an avoidance action. In view of this, and as seen in the accident presented in this report, this allows some understanding of thefact that the third officer of Vessel A in question only changed heading course by 6 degrees.
