BOTH INTERNATIONAL & INLAND You are watching another vessel approach and her compass bearing is not changing. What does this indicate?

Correct Answer: Option C — a risk of collision exists

Rule 7(d)(i) establishes that a constant compass bearing with an approaching vessel is a definitive sign of a collision risk. When the bearing remains steady, the vessels are maintaining a constant relative position, which will inevitably lead to a collision unless one vessel takes appropriate avoiding action.
