For a power-driven boat under 50 meters, which lights must be displayed in addition to red and green sidelights and a masthead 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 Bow light
• D. Red sidelights only, a Masthead light, and a Stern light

Answer: (A)

The lights required for a power-driven vessel that’s underway and under 50 meters are red and green sidelight(s) plus white lights: a masthead light visible ahead and a stern light visible astern. This setup lets other mariners tell your direction and heading at night: the sidelight colors mark the port and starboard sides, the masthead light shows you are moving, and the stern light confirms your rearward visibility. So the best choice lists red and green sidelights, a masthead light, and a stern light. A bow light isn’t required for this vessel size and situation. Options that include a bow light add an extra light that isn’t mandated here, while omitting the stern light or omitting one sidelight would fail to meet the standard requirements.
