Question 1223Deck General70% to pass
When bunkering at a dock which of the following signals must be displayed?
AI Explanation
The correct answer is B) A red flag by day, red light by night.
This is the correct answer because the International Code of Signals requires a red flag to be displayed by day and a red light to be displayed by night when a vessel is bunkering or transferring fuel at a dock or alongside. This signifies that the vessel is engaged in an operation that restricts its ability to maneuver.
The other options are incorrect because they do not match the standard signaling requirements for bunkering operations. A yellow flag, green flag, or blue light would not be the proper signals to display in this situation.
