Question 50 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is B **Explanation for Option B (A vessel is in distress):** According to both the International Regulations for Preventing Collisions at Sea (COLREGs) (specifically Annex IV) and the corresponding Inland Rules, a fog whistle or any sound signaling appliance that is continuously sounded indicates that the vessel is in distress and requires assistance. This is a universally recognized distress signal used when conditions (such as fog or restricted visibility) necessitate the use of sound signals. **Why the other options are incorrect:** * **A) A request that the draw span of a bridge to be opened:** Bridge opening requests (especially under U.S. Inland Rules) typically involve specific whistle signals (often one long blast followed by one short blast or similar patterns) or radiotelephone communication, but never a continuous sounding of the whistle. * **C) That the vessel is anchored:** When anchored in restricted visibility, a vessel uses specific prescribed signals—usually rapid ringing of the bell for 5 seconds every minute, optionally supplemented by a gong (for vessels 100 meters or more). A continuous blast is not the signal for being anchored. * **D) A vessel is broken down and drifting:** While a broken-down vessel may be in distress, "broken down and drifting" is not the specific meaning of a continuous whistle blast. A vessel that is broken down but still underway or not in immediate peril would use the required underway signals (if making way) or anchoring signals (if setting anchor). The continuous sounding is reserved exclusively for the condition of distress (requiring help).
