Question 49 FCP01 - First Class Pilot

The Correct Answer is C **Explanation for Option C (The vessel is in distress):** According to the International Regulations for Preventing Collisions at Sea (COLREGs), Annex IV, which details Distress Signals, the firing of a gun or continuous firing of an explosive signal at intervals of about one minute is a recognized and designated signal indicating that a vessel is in **distress** and requires assistance. This signal is designed to be loud, distinct, and unmistakable, immediately alerting other vessels or shore stations that the signaling vessel is facing a grave and imminent danger. **Why the other options are incorrect:** * **A) The gun is being used to sound passing signals:** Passing signals (like those used when meeting or overtaking) are generally short, standardized blasts of a vessel’s whistle (e.g., one, two, or five short blasts). Firing a gun at one-minute intervals is a distress signal, not a standard maneuver or passing signal. * **B) All vessels are to clear the area:** While other vessels must respond to a distress signal, the firing gun signal specifically indicates the *signaling* vessel is in trouble. It is not an instruction for other vessels to vacate the entire area, but rather an urgent request for assistance. * **D) All is clear and it is safe to pass:** This signal is the direct opposite of "all is clear." The repeated firing of a gun is an internationally recognized danger signal, warning of an emergency situation, not confirming safety.
