Question 49 ONC06 - Master LT 100 GRT

The Correct Answer is C The vessel is in distress. **Explanation for C (Correct Answer):** The signal described—the firing of a gun or other explosive signal at intervals of approximately one minute—is a globally recognized distress signal as defined in Annex IV of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both international and inland waters. This specific signal is universally understood to mean that the vessel transmitting it is in grave and imminent danger and requires immediate assistance. **Explanation of Incorrect Options:** * **A) The gun is being used to sound passing signals:** Passing signals (such as one, two, or three short blasts) are typically sounded using a whistle or horn and are used to communicate intentions when vessels are meeting, crossing, or overtaking. Firing a gun at one-minute intervals is far too slow and distinct to be interpreted as a maneuvering or passing signal. * **B) All vessels are to clear the area:** While the presence of a distressed vessel might necessitate other vessels maneuvering to avoid collision or assist, the primary indication of the one-minute gun signal is distress and the need for assistance, not a general instruction for all vessels to evacuate the vicinity. * **D) All is clear and it is safe to pass:** This signal is the precise opposite of "all clear." As a recognized distress signal, it indicates a critical emergency situation, not safety.
