Question 32 GLI08 - Limited OUPV

The Correct Answer is D **Explanation for D (A flaming barrel of oil on deck):** Option D, "A flaming barrel of oil on deck," is a internationally recognized distress signal under Annex IV of the International Regulations for Preventing Collisions at Sea (COLREGs). Specifically, Annex IV, paragraph 1(i) includes "a light shown by any method which is a highly intensive white light flashing at regular intervals at a rate of fifty to sixty times per minute" as a distress signal. However, more broadly, the appearance of flames on the vessel (as from a burning barrel or other source) is a classic and universally understood visual indication that the vessel is in grave and imminent danger and requires assistance. The spectacle of flames on the vessel is listed in similar regulatory contexts as an emergency signal. **Explanation why the other options are incorrect:** * **A) Answering a one blast whistle signal with two blasts:** This is a maneuver signal, not a distress signal. Under COLREGs Rule 34, a vessel operating in sight of another may use short blasts to indicate intent (one blast = "I am altering my course to starboard," etc.). Answering with two blasts typically means acknowledging the signal and indicating your intent to pass on the other's port side (or similar agreed-upon maneuver), particularly in confined waters. * **B) Sounding 5 short blasts on the whistle:** This signal is prescribed by COLREGs Rule 34(d) as the **doubt** or **danger** signal. It means, "I am unsure of your intent or actions," or "I doubt if sufficient action is being taken to avoid collision." While it indicates a potentially hazardous situation, it is a warning and collision-avoidance signal, not a formal distress signal that signifies the vessel requires immediate outside assistance (Mayday). * **C) Firing of green star shells:** The firing of **red** star shells is a recognized distress signal (COLREGs Annex IV, 1(g)). Green flares or star shells, conversely, are typically used for signaling within a fleet, marking a location, or indicating non-distress status (such as a position indication flare) and are not recognized as a signal of distress.
