BOTH INTERNATIONAL & INLAND Which vessel must show an after masthead light, if over 50 meters in length?
AI Explanation
The correct answer is A) A vessel trawling.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel over 50 meters in length, when trawling (fishing with nets or other fishing apparatus that restricts maneuverability), must show an after masthead light in addition to the other required navigation lights.
The other options are incorrect because: B) A vessel engaged in fishing, but not trawling, does not require an after masthead light; C) A vessel not under command is required to show different navigation lights; and D) A vessel at anchor is required to show a different set of lights.
