BOTH INTERNATIONAL & INLAND What is the minimum vessel length which must show two white masthead lights, one forward and one aft, when underway at night?
AI Explanation
The correct answer is A) 100 meters.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel 100 meters or more in length when underway must display two white masthead lights, one forward and one aft. This requirement applies to both international and inland waterways. Vessels less than 100 meters in length are not required to have this specific lighting configuration, which is why options B, C, and D are incorrect.
