Question 50 UFV01 - Master - Uninspected Fishing Vessels

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, Rule 37) and the Inland Rules (which largely mirror the international distress signals), the continuous sounding of any fog-signaling apparatus is a recognized signal of **distress**. This signal is highly urgent and indicates that the 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:** Bridge opening requests are typically made using short, distinct whistle blasts (e.g., one prolonged blast followed by one short blast, depending on the region and specific bridge requirements), not a continuous sounding of the fog whistle. * **C) That the vessel is anchored:** A vessel at anchor or aground in fog gives specific sound signals (typically a rapid ringing of the bell for 5 seconds every minute, possibly followed by a gong or a short-prolonged-short whistle signal, depending on the size of the vessel and whether it is international or inland waters). A continuous blast is not the signal for being anchored. * **D) A vessel is broken down and drifting:** While a broken-down vessel may eventually use a distress signal if its situation becomes dangerous, the standard signal for distress (B) is the continuous sounding. There is no separate, specific standard sound signal purely indicating a vessel is broken down and drifting without being in immediate distress (unless it is a vessel being towed or constrained by its ability to maneuver, which have other regulated signals).
