Question 235 Rules of the Road

The correct answer is C) You must sound the danger signal. In this situation, where you are navigating in a narrow channel and another vessel is crossing the channel ahead of you from your starboard side, and you doubt whether your vessel will pass safely, the appropriate action is to sound the danger signal. This is in accordance with the Inland Navigation Rules, which state that when a vessel doubts whether it can safely avoid a collision, it must immediately indicate such doubt by sounding the danger signal. The other options are incorrect because: A) Stopping the engines and sounding the danger signal is not the correct action in this situation; B) You do not need to stop your vessel, as the other vessel is the give-way vessel; and D) Sounding one short blast and turning to starboard is not the appropriate action when you doubt the safety of the situation.
