What type of lights do power vessels under 12m require?

• A. Red and green sidelights only
• B. Flashing blue lights
• C. All around white light and sidelights
• D. Only a stern light

Answer: (C)

Power vessels under 12 meters in length are required to display an all-around white light at anchor and sidelights while underway. The all-around white light serves to indicate the presence of the vessel to other boats, ensuring visibility in various conditions. Meanwhile, the sidelights, which consist of a red light on the port side and a green light on the starboard side, allow other vessels to determine the orientation and direction of the power vessel when it is moving. This configuration is essential for compliance with navigation rules and helps prevent collisions on the water by clearly marking the vessel's position and direction. The requirement for both sidelights and an all-around white light is established to create a clear and predictable signaling system, particularly since smaller vessels may be harder to see in certain conditions.
