Question 41 GLI07 - OUPV

The Correct Answer is A. **Explanation for A (The vessel's searchlight):** According to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 36 (Signals to attract attention), a vessel may, if necessary, use a searchlight to attract the attention of another vessel. The light must be directed in such a way as not to interfere with the navigation of the other vessel. This signal is explicitly permitted for attracting attention and is distinct from a distress signal. **Explanation for B (A red star shell):** A red star shell is specifically listed in Annex IV of the COLREGs as one of the internationally recognized distress signals. Using this signal would indicate that the vessel is in grave and imminent danger and requires assistance, not merely that it wants to attract attention. **Explanation for C (A burning barrel):** A burning barrel (or any fire on board, such as oil or tar in a barrel) produces flames and smoke, which is one of the recognized distress signals listed in Annex IV of the COLREGs. Using this would convey distress. **Explanation for D (An orange smoke signal):** An orange smoke signal (whether a can or a flare) is explicitly listed in Annex IV of the COLREGs as one of the internationally recognized distress signals. Using this would convey distress.
