Question 41 GLI05 - 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 of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both international and inland waters (where local rules align or defer to COLREGs). Rule 36, "Signals to Attract Attention," states: "Any vessel may use any light or sound signal 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 a manner that will not embarrass any vessel." Directing the beam of the vessel's searchlight is explicitly authorized as a means to attract attention, provided it does not cause confusion or interfere with navigation. **Explanation for why other options are incorrect:** * **B) A red star shell:** A red star shell (or rockets/shells throwing red stars) is explicitly listed in Annex IV of COLREGs (Distress Signals) as a signal indicating that a vessel is in **distress** and requires assistance. Using it merely to attract attention when not in distress is a violation and highly dangerous, as it would initiate a full emergency response. * **C) A burning barrel:** A signal consisting of flames on the vessel (like a burning barrel) is also listed in Annex IV of COLREGs as a **distress signal**. Using this signal when not in distress is forbidden. * **D) An orange smoke signal:** An orange smoke signal is specifically listed in Annex IV of COLREGs as a recognized **distress signal**. Using an orange smoke signal when not in distress is strictly prohibited.
