Question 599Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND Which of the following describes a vessel exhibiting the lights shown in illustration D056RR below?
AI Explanation
The correct answer is A) underway and laying submarine cable.
This is correct because the illustration D056RR depicts the navigation lights required for a vessel that is underway and engaged in the laying of submarine cable. The lights shown - all-round white lights at the masthead and stern - are the required lights for this type of vessel operation, as specified in the International and Inland Navigation Rules.
The other answer choices do not accurately describe the lighting configuration shown in the illustration. Vessels at anchor, carrying dangerous cargo, or towing a barge would have different navigation light requirements that do not match the illustration.
