Question 979Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway in fog you hear a whistle signal consisting of one prolonged blast followed immediately by two short blasts. Which vessels are required to sound this signal in fog?
AI Explanation
The correct answer is D) Vessels underway and towing.
The International Regulations for Preventing Collisions at Sea (COLREGS) require vessels underway and towing another vessel to sound the signal of one prolonged blast followed by two short blasts in fog. This signal indicates the vessel's presence and its restricted maneuverability due to the tow.
Options A, B, and C are incorrect because the COLREGS do not require those types of vessels to sound this specific signal in fog. Vessels in danger may sound other distress signals, pilot vessels have different signaling requirements, and anchored vessels not engaged in fishing do not need to sound this towing signal.
