Question 144 Rules of the Road

90% to pass

BOTH INTERNATIONAL & INLAND You are approaching a narrow channel. Another vessel in the channel can only be navigated safely in that channel. Which action should you take?

A sound two prolonged blasts followed by one short blast
B sound three short blasts, and take all way off your vessel
C hold your course and speed if she is on your port bow
D not cross the channel if you might impede the other vessel
AI Explanation

The correct answer is D) not cross the channel if you might impede the other vessel. The reasoning behind this is that when approaching a narrow channel, the COLREGS (International Regulations for Preventing Collisions at Sea) require vessels to not impede the safe passage of a vessel that can only navigate safely within the channel. Crossing the channel in this situation could create a dangerous situation, so the best course of action is to not cross if it might impede the other vessel. The other options are incorrect because they do not properly address the need to avoid impeding the other vessel's safe passage through the narrow channel, which is the primary concern in this scenario.
