Question 990Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A vessel engaged in fishing while at anchor shall sound which fog signal?
AI Explanation
The correct answer is B) One prolonged and two short blasts at two minute intervals.
This is correct because under both the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel engaged in fishing while at anchor is required to sound this fog signal. The regulations specify that this signal should be sounded at two-minute intervals to indicate the vessel's presence and activity to other vessels in the area.
The other answer choices are incorrect because they do not match the specific fog signal required for a fishing vessel at anchor under the rules. Option A describes a different signal, option C describes a different signal and interval, and option D describes a combination of signals not prescribed for this situation.
