Question 50 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is B **Why option B ("A vessel is in distress") is correct:** Under both the International Regulations for Preventing Collisions at Sea (COLREGs) and the U.S. Inland Rules, the continuous sounding of any fog-signaling apparatus (such as a fog whistle or horn) is universally recognized as a signal of distress. This specific, prolonged acoustic signal is an internationally defined alarm meant to alert nearby vessels and authorities that the signaling vessel is in grave danger and requires immediate assistance. **Why the other options are incorrect:** * **A) A request that the draw span of a bridge to be opened:** Requests for bridge openings are typically made using short, distinct blasts (e.g., one long blast followed by one short blast, depending on the waterway and local rules) or via radio communication, not a continuous sounding of the fog whistle. * **C) That the vessel is anchored:** A vessel anchored in fog signals its presence by ringing the bell rapidly for five seconds at intervals of not more than one minute (for vessels 100 meters or more in length), often supplemented by a gong in the after part of the vessel, but it does not continuously sound the fog whistle. Smaller anchored vessels use other distinct signals or means. * **D) A vessel is broken down and drifting:** While a broken down and drifting vessel may be in peril, the specific signal indicating *distress* (which encompasses being broken down and requiring immediate help) is the continuous sounding of the fog whistle. Standard maneuvering or warning signals for a disabled vessel would involve specific short/long blasts or use of the danger signal (five or more short blasts) if a collision risk exists, not a continuous blast.
