BOTH INTERNATIONAL & INLAND A towing vessel 30 meters in length is pushing barges ahead. How many white masthead lights is the vessel REQUIRED to show at night?
AI Explanation
The correct answer is B) Two.
According to the International and Inland Navigation Rules, a towing vessel 30 meters or more in length pushing barges ahead is required to display two white masthead lights at night. This is specified in Rule 23(b) of the Navigation Rules, which states that a power-driven vessel when pushing ahead or towing alongside shall exhibit two masthead lights in a vertical line. The other answer choices are incorrect because a towing vessel of this size is not required to display one, three, or four masthead lights.
