INLAND ONLY At night, which lights are required on barges moored in a group formation, more than two barges wide, and located where other vessels cannot navigate on both sides of the group?

A Two red lights in a vertical line at the corner extremities of the group
B All-round white lights placed at the corners of each barge in the group
C Two unobstructed all-round white lights
D Two unobstructed all-round yellow lights
AI Explanation

The correct answer is C) Two unobstructed all-round white lights. This is because the Inland Navigation Rules, Rule 30(e), states that a barge or group of barges at anchor or moored in a group more than two barges wide and located where other vessels cannot navigate on both sides of the group must display two unobstructed all-round white lights in a vertical line. The other answer choices are incorrect because they do not align with the specific requirements outlined in the Inland Navigation Rules for this scenario. For example, red lights (option A) and yellow lights (option D) are not the correct color as per the regulations.
