Question 503Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND What is the minimum length of an anchored vessel which is required to show a white light both forward and aft?
AI Explanation
The correct answer is D) 50 meters.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), which apply to both international and inland waterways, the requirement to display a white light both forward and aft applies to vessels 50 meters or more in length when at anchor. Vessels less than 50 meters in length are not required to have these anchor lights.
The other options are incorrect because 200 meters, 150 meters, and 100 meters are all greater than the 50-meter threshold specified in the COLREGS.
