Question 41 TV02 - Towing Vessels - Great Lakes and Inland

The Correct Answer is A. **Explanation for A (The vessel's searchlight):** Rule 36 of the International Regulations for Preventing Collisions at Sea (COLREGs) specifically addresses signals to attract attention. It states that "Any vessel may, if necessary to attract the attention of another vessel, use 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 is a recognized and permitted method, outside of distress signals, to attract attention. **Explanation for B (A red star shell):** A red star shell is explicitly listed in Annex IV of COLREGs (Distress Signals) as a signal indicating distress and a need for assistance. Using it for mere attention-getting is incorrect and illegal, as it constitutes a false distress signal. **Explanation for C (A burning barrel):** A signal consisting of flames on the vessel (such as a burning barrel of oil or waste) is listed in Annex IV of COLREGs as a distress signal. Using it for mere attention-getting is incorrect. **Explanation for D (An orange smoke signal):** An orange smoke signal is specifically listed in Annex IV of COLREGs as a distress signal. Using it for mere attention-getting is incorrect.
