BOTH INTERNATIONAL & INLAND Which lights would be shown at night by a vessel which is restricted in her ability to maneuver?

Correct Answer: Option A — Three lights in a vertical line, the highest and lowest red and the middle white

Rule 27(b)(i) mandates that a vessel restricted in her ability to maneuver must display three all-round lights in a vertical line. The highest and lowest lights must be red, and the middle light must be white. These lights are essential for identifying the vessel's status to other mariners at night.
