BOTH INTERNATIONAL & INLAND A 49 meter seagoing tug has a tow greater than 200 meters as shown in illustration D024RR below and is severely restricted in her ability to deviate from her course. Which lights would be displayed from the towing vessel?

Correct Answer: Option B — Three white masthead lights, red-white-red all-round lights, sidelights, stern light and a towing light

Rule 24(a) and Rule 27(b) require a vessel restricted in her ability to maneuver, when towing, to display three masthead lights in a vertical line, sidelights, a stern light, a towing light, and the red-white-red all-round lights. The tow length exceeding 200 meters necessitates the third masthead light.
