BOTH INTERNATIONAL & INLAND When do the Rules state that risk of collision shall be deemed to exist?

Correct Answer: Option A — if the bearing of an approaching vessel does not appreciably change

Rule 7(d)(i) explicitly defines that risk of collision shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change. This objective standard provides mariners with a clear, measurable indicator to identify potential hazards, regardless of the specific geometry of the approach.
