Alteration of course alone

  • Rule(s) to be applied: Rule 8 (Action to avoid collision )
  • Applying the Rule(s) and comments: In accordance with Rule 8 (c) (Action to avoid collision ), if there is sufficient sea-room, alteration of course alone may be the most effective action to avoid a close-quarters situation provided that it is made in good time, is substantial and does not result in another close-quarters situation.
    Comments:
    Generally, speed alteration is rather difficult to observe as such is difficult to assess the situation, because, the apparent track remains the same. Thus, a course alteration is much more effective in diffusing a dangerous situation and also is readily apparent to the other vessel – provided however, that the alteration can be observed very easily by the other vessel.
