Question

BOTH INTERNATIONAL & INLAND Which lights shall a power-driven vessel towing another vessel astern (tow less than 200 meters) show?

A) three masthead lights in a vertical line instead of either the forward or after masthead light
B) two towing lights in a vertical line at the stern
C) two masthead lights in a vertical line instead of either the forward or after masthead lights
D) a small white light aft of the funnel

Answer 1

A power-driven vessel towing another with a tow less than 200 meters must exhibit two masthead lights in a vertical line, ensuring that its status is clear to other vessels to prevent collisions.

Step-by-step explanation:

The lights that a power-driven vessel towing another vessel astern, with a tow less than 200 meters, should show according to both International and Inland Rules are a forward masthead light, one after another, the towing light in a vertical line above the sternlight, and sidelong-on lights.

The correct answer is C) two masthead lights in a vertical line instead of either the forward or after masthead lights. This helps other vessels to identify the towing operation during nighttime or in reduced visibility conditions. These navigational lighting configurations are standardized to prevent collisions and provide information about a vessel's size, activity, and direction of movement.
