Question 50

The Correct Answer is B **Why option B ("A vessel is in distress") is correct:** According to both the International Regulations for Preventing Collisions at Sea (COLREGs) Rule 35(c) and the corresponding Inland Rules, a continuous sounding of a fog whistle (or any prolonged sounding of the whistle) signifies that the vessel is in distress and requires assistance. This signal is universally recognized as an urgent plea for help. **Why the other options are incorrect:** * **A) A request that the draw span of a bridge to be opened:** Bridge opening requests are typically made using specific short and prolonged blasts (e.g., one prolonged blast followed by one short blast, depending on local regulations), not a continuous sounding of the whistle. * **C) That the vessel is anchored:** When anchored in restricted visibility, a vessel must sound rapid ringing of the bell for 5 seconds every minute (for vessels 100 meters or more, the bell must be followed by the gong), not a continuous fog whistle. * **D) A vessel is broken down and drifting:** While a broken-down vessel may certainly be in distress, the specific signal for a vessel *not* under command (which covers most broken-down situations) is typically specified by lighting or shape signals (e.g., two all-around red lights) and specific maneuvering signals, not solely a continuous whistle, unless that situation escalates into one of urgent distress. The continuous whistle is the definitive distress signal.
