Question 49 ONC02 - Second Mate/Third Mate Unlimited Tonnage

The Correct Answer is C **Why option C ("The vessel is in distress") is correct:** According to the International Regulations for Preventing Collisions at Sea (COLREGs), Annex IV (Distress Signals), the firing of a gun or other explosive signal at intervals of about one minute is a globally recognized signal indicating that a vessel is in distress and requires assistance. This signal is unambiguous and must be treated as a genuine emergency. **Why the other options are incorrect:** * **A) The gun is being used to sound passing signals:** Passing signals (like those used in restricted visibility) are typically short blasts on the whistle or horn, not the firing of a gun at one-minute intervals. The firing of a gun is reserved for indicating distress. * **B) All vessels are to clear the area:** While other vessels must take action when a distress signal is heard (namely, offering assistance if safe to do so), the primary meaning of the signal is "I am in distress," not a command for others to vacate the area. * **D) All is clear and it is safe to pass:** A distress signal indicates a severe emergency. It signifies danger and the need for help, which is the direct opposite of indicating that conditions are safe or clear to pass.
