Question 712Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A towing vessel is towing two barges astern. The length of the tow from the stern of the tug to the stern of the last barge is 250 meters. The towing vessel is 45 meters in length. How many white masthead lights should be displayed on the tugboat at night?
AI Explanation
The correct answer is C) 3 white masthead lights.
According to the International and Inland Navigation Rules, a towing vessel must display 3 white masthead lights when towing another vessel(s) astern, where the length of the tow, measured from the stern of the towing vessel to the stern of the last vessel in the tow, exceeds 200 meters. In this case, the length of the tow is 250 meters, which requires the display of 3 white masthead lights on the tugboat.
The other options are incorrect because: A) 1 light is not enough for a tow this long, B) 2 lights are not sufficient, and D) 4 lights would be more than the required 3 lights.
