Question 50 GLI05 - Master or Mate of LT 200 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) and the U.S. Inland Rules, a continuous sounding of the fog whistle (or any appropriate signaling device) is designated as an internationally recognized signal indicating that a vessel is in distress and requires assistance. This is a critical safety signal used when danger threatens and immediate help is necessary. **Why the other options are incorrect:** * **A) A request that the draw span of a bridge to be opened:** Bridge signals typically involve specific short and prolonged blasts, such as one prolonged blast followed by one short blast, depending on local rules. A continuous sounding is not the signal for requesting a bridge opening. * **C) That the vessel is anchored:** When anchored in restricted visibility, a vessel must ring the bell rapidly for five seconds every minute (for vessels 100 meters or more in length, this is followed by a gong sounding aft). A continuous whistle 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 (B), the specific signal for a vessel restricted in its ability to maneuver (like a vessel broken down but not necessarily in immediate peril) involves specific sound signals (e.g., one prolonged blast followed by two short blasts) when making way. A continuous blast specifically denotes *distress*, which is a more urgent situation than simply being broken down or drifting.
