INTERNATIONAL ONLY In a narrow channel, a signal of intent which must be answered by the other vessel, is sounded during which of the following situations?

A A vessel crossing the course of another
B A vessel meeting another head-on
C A vessel overtaking in a narrow channel
D All of the above
AI Explanation

The correct answer is C) A vessel overtaking in a narrow channel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel overtaking another in a narrow channel must sound a signal of intent, which the other vessel must answer. This is specified in Rule 34(c) of the COLREGS. The other answer choices, such as a vessel crossing the course of another (Rule 15) or a vessel meeting another head-on (Rule 14), do not require the specific signal of intent that is necessary when one vessel is overtaking another in a narrow channel.
