Diagram for USCG Rules of the Road: INTERNATIONAL ONLY At night you sight the lights shown in illustration D066RR...
A Two vessels pair trawling
B A vessel engaged in fishing
C A tug with a tow alongside
D A ship being assisted by a tug
AI Explanation

The correct answer is C) A tug with a tow alongside. The lights shown in illustration D066RR at night indicate a tug vessel with a tow vessel alongside. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which specify the navigation lights required for different types of vessels. The other options are incorrect because: A) Two vessels pair trawling would have different light configurations, B) A vessel engaged in fishing would have different light arrangements, and D) A ship being assisted by a tug would have additional lights indicating the towing operation.
