Question 41 ONC02 - Second Mate/Third Mate Unlimited Tonnage

The Correct Answer is A. **Explanation for A (The vessel's searchlight):** According to Rule 36 of the International Regulations for Preventing Collisions at Sea (COLREGs), if a vessel desires to attract the attention of another vessel, any light or sound signal that cannot be mistaken for any signal authorized elsewhere in the Rules may be used. Specifically, Rule 36 permits the use of a searchlight beam directed in the direction of the danger or vessel being hailed in order to attract attention. This practice is recognized internationally and for inland waters, provided it does not impair the visibility of other required navigation lights. **Explanation for Incorrect Options:** **B) A red star shell:** A red star shell is a recognized signal of **distress** (Annex IV, COLREGs). Using a distress signal to merely attract attention when no distress exists is prohibited, as it sends a false emergency alert. **C) A burning barrel:** A flame on the vessel (such as a burning barrel or oil drum) is a traditional and recognized signal of **distress** (Annex IV, COLREGs). **D) An orange smoke signal:** An orange smoke signal is a recognized signal of **distress** (Annex IV, COLREGs). Like the other distress signals, it cannot be used solely to attract attention under normal circumstances.
