Question 569 Rules of the Road

The correct answer is A) After the towing vessel's fog signal. The reasoning is that according to the Inland and International Navigation Rules, when a manned vessel is being towed, the towing vessel must sound the fog signal, and the manned vessel being towed must sound its fog signal after the towing vessel's signal. This ensures that both vessels are clearly identified and their relative positions are known to other vessels in the area. The other options are incorrect because B) would be out of sequence, C) would allow the manned vessel to not sound a fog signal, which is not permitted, and D) would have the manned vessel sounding its signal too early compared to the towing vessel's signal.
