Question 48 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is C **Explanation for Option C (Correct Answer):** Option C, "One prolonged and two short blasts at two-minute intervals," is the correct fog signal for a vessel restricted in its ability to maneuver, which includes a vessel engaged in fishing while anchored in or near an area of restricted visibility. This is governed by **Rule 35 (Fog Signals) of the International Regulations for Preventing Collisions at Sea (COLREGs)**. * **Rule 35(c)** specifies the signal for a vessel **not under command**, a vessel **restricted in its ability to maneuver** (RAM), a vessel **constrained by its draught**, a **sailing vessel**, a vessel **engaged in towing or pushing**, or a vessel **engaged in fishing** (among others, when they are making way). * **Rule 35(g)** specifies the signal for a vessel **at anchor** (a rapid ringing of the bell for five seconds at intervals of not more than one minute). However, a vessel **engaged in fishing** (by definition, a vessel restricted in its ability to maneuver) **while at anchor** is considered a vessel **restricted in its ability to maneuver** that is **at anchor**. COLREGs priority dictates that the signal for the more restrictive condition (RAM) usually applies, or, specifically in this context, the signal for the RAM vessel takes precedence over the standard anchor signal. The specific signal for a vessel **restricted in its ability to maneuver** (RAM) is: **one prolonged blast followed by two short blasts** at intervals of not more than two minutes. **Why the Other Options Are Incorrect:** * **A) A rapid ringing of the bell for five seconds at one-minute intervals:** This is the standard fog signal for a vessel **at anchor** (Rule 35(g)). While the vessel is anchored, because it is also engaged in fishing (a RAM status), the RAM signal (C) takes precedence to alert other vessels to its restricted status. * **B) One prolonged and three short blasts at two-minute intervals:** This signal (Rule 35(e)) is used by a vessel being towed or, if manned, the last vessel in a tow. It is not the signal for a vessel engaged in fishing. * **D) A sounding of the bell and gong at one-minute intervals:** This signal (Rule 35(g)) is reserved for a vessel at anchor that is **100 meters or more in length**. While the vessel might be large, it does not account for the primary status of being engaged in fishing (RAM), which requires the sound signal in Rule 35(c).
