BOTH INTERNATIONAL & INLAND Which vessel must show a masthead light abaft of and higher than her identifying lights?
AI Explanation
The correct answer is B) A 55-meter vessel trawling.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in trawling, which includes fishing with nets or other fishing apparatus that restrict maneuverability, must exhibit a masthead light abaft of and higher than the sidelights. This requirement applies to vessels 50 meters or more in length.
The other options are incorrect because: A) a vessel not under command is not required to exhibit this specific light configuration, C) a vessel engaged on pilotage duty is not required to exhibit this light, and D) a vessel fishing (but not trawling) is not required to exhibit this masthead light.
