BOTH INTERNATIONAL & INLAND In fog you observe your radar and determine that risk of collision exists with a vessel which is 2 miles off your port bow. Which action should you take?

Correct Answer: Option B — take avoiding action as soon as possible

Rule 7(d) and Rule 19(d) require that if risk of collision is determined by radar, you must take avoiding action in ample time. In restricted visibility, you cannot rely on the other vessel to act; you must maneuver to avoid a close-quarters situation as soon as risk is detected.
