Diagram for question 823
AI Explanation
The correct answer is C) sailing vessel. The illustration D080RR shows a red sidelight, which indicates that the vessel is a sailing vessel. According to the International and Inland Navigation Rules, sailing vessels must display a red sidelight on the port (left) side of the vessel when underway. This allows other vessels to identify the sailing vessel and take the appropriate action to avoid a collision. The other answer choices are incorrect because a vessel on pilotage duty (A) would display different navigation lights, a law enforcement vessel (B) would typically display flashing blue or red lights, and a vessel engaged in fishing (D) would display different navigation lights specific to fishing vessels.
