BOTH INTERNATIONAL & INLAND A vessel is displaying ONLY the lights shown in illustration D053RR below. What type of vessel is this?
AI Explanation
The correct answer is C) vessel engaged on pilotage duty underway.
The lighting configuration shown in illustration D053RR, with only the red and green sidelights and white masthead light, indicates a power-driven vessel underway and engaged in pilotage duty. As per the navigation rules, a vessel on pilotage duty is not required to display the stern light or the range of lights typically seen on a standard power-driven vessel underway. The absence of the additional lights rules out the other options, such as a vessel under sail or a fishing vessel.
