Question 48 GLI01 - Master-Unlimited Tonnage

The Correct Answer is C **Explanation for C (Correct Answer):** Option C, "One prolonged and two short blasts at two-minute intervals," is the correct fog signal specified by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 35(c), for a **vessel restricted in her ability to maneuver (RAM)** or a **vessel engaged in fishing,** among others, when making way through the water. * **Crucially, Rule 35(e) specifies that a vessel, when at anchor and engaged in fishing, is required to give the signal prescribed in Rule 35(c).** * Therefore, the signal for a vessel engaged in fishing, while at anchor, is **one prolonged blast followed by two short blasts** (— • •) at intervals of not more than two minutes. This signal alerts other vessels that they are approaching a vessel that cannot easily change course and/or is obstructed (by its fishing gear). **Explanation of Why 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** (COLREGs Rule 35(f)), which has a length of 100 meters or more. While a vessel engaged in fishing is *also* at anchor, it must sound the specific signal defined in 35(c) or (e) (the fishing/RAM signal), overriding the general anchor signal. * **B) One prolonged and three short blasts at two-minute intervals:** This signal (— • • •) is specified for a vessel **being towed** (COLREGs Rule 35(e)). 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 involves a rapid ringing of the bell for 5 seconds and, immediately after, a rapid sounding of the gong for 5 seconds, at intervals of not more than one minute. This is the signal for a vessel **at anchor** that is **100 meters or more in length** (COLREGs Rule 35(f)). It is not the specific signal required for a vessel engaged in fishing while at anchor.
