Question 41 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is A. **Explanation for A (The vessel's searchlight):** Option A is correct based on Rule 36 (Signals to attract attention) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both international and inland waters (where the Inland Rules adopt or parallel the COLREGs). Rule 36 explicitly states: "If necessary to attract the attention of another vessel, any vessel may make light or sound signals that cannot be mistaken for any signal authorized elsewhere in these Rules, or may direct the beam of her searchlight in the direction of the danger, in such a way as not to embarrass any vessel." Directing a searchlight beam towards a vessel or danger is a recognized and legal means to attract attention, provided it is done without causing confusion or blinding the other vessel's navigation. **Explanation for Incorrect Options:** * **B) A red star shell:** This is incorrect because a red star shell is a recognized international distress signal (Annex IV of COLREGs). The question specifically asks for a signal *other than* a distress signal. * **C) A burning barrel:** This is incorrect because a burning barrel or anything alight on deck is a classic, recognized international distress signal (Annex IV of COLREGs). * **D) An orange smoke signal:** This is incorrect because an orange smoke signal is a recognized international distress signal (Annex IV of COLREGs).
