Question 50 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is B A continuous sounding of a fog whistle (or any prolonged sounding device) by a vessel, under both the International Regulations for Preventing Collisions at Sea (COLREGs) and Inland Rules, is the designated signal for **distress**. Specifically, Rule 37 and Annex IV of COLREGs list various internationally recognized distress signals, one of which is the continuous sounding with any fog-signaling apparatus. ### Why other options are incorrect: **A) A request that the draw span of a bridge to be opened:** Requests for bridge openings typically involve specific short signals (like one long blast followed by one short blast, or four to five short blasts, depending on location and local rules). A continuous sounding is not the standard signal for this request. **C) That the vessel is anchored:** When anchored in fog, vessels signal their position by rapidly ringing the bell for about 5 seconds at intervals of not more than one minute (for vessels 100 meters or more, they also sound a gong after the bell). A continuous blast is not used. **D) A vessel is broken down and drifting:** While a vessel that is broken down may be in distress, the specific signal indicating the mechanical status ("not under command" or "broken down") in restricted visibility is typically two prolonged blasts followed by one short blast. A continuous blast specifically denotes the emergency of distress, not just a disabled status.
