BOTH INTERNATIONAL & INLAND A vessel is displaying ONLY the lights shown in illustration D045RR below. What type of vessel could this be?

Correct Answer: Option C — pilot vessel less than 50 meters, underway and NOT engaged on pilotage duty

Rule 27(d) specifies that a pilot vessel underway shall exhibit two all-round lights in a vertical line, the upper being white and the lower red. If the vessel is not engaged on pilotage duty, it must exhibit the lights prescribed for a similar power-driven vessel of its length.
