Question 394Rules of the Road90% to pass
INTERNATIONAL ONLY You are operating a vessel in a narrow channel. Your vessel must stay within the channel to be navigated safely. Another vessel is crossing your course from starboard to port, and you are in doubt as to his intentions. According to Rule 9, which statement is TRUE?
AI Explanation
The correct answer is C) You may sound the danger signal.
According to Rule 9 of the International Regulations for Preventing Collisions at Sea (COLREGS), when operating in a narrow channel, if you are in doubt as to the other vessel's intentions, you may sound the danger signal. This is because the other vessel is crossing your course from starboard to port, which could indicate a potential collision risk.
The other answer choices are incorrect. Option A is incorrect because sounding one short blast would indicate that you are holding course and speed, which is not appropriate in this situation where you are in doubt. Option B is incorrect because you are not required to back down. Option D is incorrect because sounding one prolonged and two short blasts is the signal to indicate you are unsure of the other vessel's intentions, not the danger signal.
