A power-driven boat less than 50 meters in length must display red and ______ sidelights, a masthead light, and a ______ light.

• A. Red and Green sidelights, a Masthead light, and a Stern light
• B. Red and Green sidelights, a Masthead light, and a Bow light
• C. Red and Green sidelights, a Stern light, and a Port light
• D. Red sidelights only, a Masthead light, and a Stern light

Answer: (A)

When a power-driven vessel under 50 meters is underway at night, it must show navigation lights that reveal its direction and status. The red and green sidelights identify the port and starboard sides, so other vessels know which way you’re facing. A white masthead light signals that you are underway and heading forward, and a white stern light marks the rear of the vessel. This combination provides clear, standard visibility to other mariners. The correct set is red and green sidelights, a masthead light, and a stern light because it includes both required sidelights, a forward-facing masthead light, and a rear-facing stern light. Other options fail because they replace or omit the stern light or misstate the sidelights.
