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) establishes that risk of collision is deemed to exist when the compass bearing of an approaching vessel does not change appreciably. This rule serves as the primary indicator for mariners to identify a collision threat, necessitating compliance with the steering and sailing rules.
