Question 48 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is C **Explanation of Correctness (Option C):** 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 (RAM), a towing vessel, or a vessel engaged in fishing, when making way or at anchor (if required to signal). * **Basis in COLREGs:** The International Regulations for Preventing Collisions at Sea (COLREGs), Rule 35(c) and (d), specifies the fog signals for different categories of vessels. * Rule 35(c) states that a vessel **not under command, a vessel restricted in her ability to maneuver, a vessel constrained by her draught, a sailing vessel, a vessel engaged in fishing, and a vessel engaged in towing or pushing** shall sound, at intervals of not more than two minutes, **one prolonged blast followed by two short blasts** (— • •). * **Application to the Vessel:** A vessel engaged in fishing, even when at anchor, falls under the category of vessels required to use the signal specified in Rule 35(c). The fact that the vessel is fishing means it is restricted in its ability to maneuver due to its gear. **Why Other Options Are Incorrect:** * **A) A rapid ringing of the bell for five seconds at one-minute intervals:** * **Incorrect Signal:** This is the required signal for a vessel **at anchor** of 100 meters or more in length (Rule 35(g)), which must sound the bell forward. It is not the signal for a vessel engaged in fishing. * **B) One prolonged and three short blasts at two-minute intervals:** * **Incorrect Signal:** This signal (— • • •) is specified in Rule 35(e) for a **manned vessel being towed**, not for a vessel engaged in fishing. * **D) A sounding of the bell and gong at one-minute intervals:** * **Incorrect Signal:** A bell and gong (or other sound signal) is used by a vessel at anchor of 100 meters or more in length (Rule 35(g)), where the bell is rung forward and the gong is sounded rapidly for about five seconds immediately after the bell. This signal occurs at intervals of not more than one minute, but it is specifically for large anchored vessels, not vessels engaged in fishing.
