BOTH INTERNATIONAL & INLAND Two barges are being pushed ahead by a tugboat. Which statement is TRUE concerning lights on the barges?

Correct Answer: Option A — The barges should be lighted as one vessel.

Rule 24(c) dictates that when a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit, they shall be regarded as a single power-driven vessel and exhibit the lights prescribed in Rule 23. Therefore, the barges are lighted as one single power-driven vessel unit.
