On sailboats and rowboats less than 7 meters, what may be displayed if regular running lights are unavailable?

• A. Lantern
• B. Torch
• C. Flashlight
• D. Flares

Answer: (C)

When running lights aren’t available on a small sailboat or rowboat, you still need to signal your vessel’s presence at night. A flashlight serves as a practical, portable light that can be quickly powered on and directed to be seen by other vessels, helping to prevent collisions. It provides a clear, white light that can be kept on the fore or in a position where it’s visible from multiple directions.

A lantern is heavier and less flexible for signaling at range, and could be mistaken for a fixed light. Flares are distress signals used for emergencies, not for routine signaling, and would be inappropriate here. A torch (flame) is unreliable in wind and can be hazardous or misinterpreted.

Thus, a flashlight is the appropriate substitute when regular running lights are unavailable.
