BOTH INTERNATIONAL & INLAND You are on vessel "B" and crossing a narrow channel. Vessel "A", who can only navigate within the channel, is on your port bow and crossing as shown in illustration D040RR below. Which action should you take?

Correct Answer: Option A — Give-way to the other vessel.

Rule 9(b) mandates that a vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel. Even if the other vessel is on your port bow, you must give way.
