Question 48 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is C **Explanation of Option 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 its ability to maneuver** (RAM). Although a vessel engaged in fishing is typically designated under Rule 35(e) to sound one prolonged and two short blasts (if moving) or specific bell/gong signals (if stopped), Rule 35(c) covers vessels that are **at anchor** and also require a distinct signal due to their specific activity (like fishing). However, the most direct and common interpretation under COLREGs Rule 35 is that a **vessel engaged in fishing (whether making way or not) shall sound a specific signal distinct from vessels at anchor (Rule 35(g)) or vessels underway (Rule 35(a)).** Rule 35(e) specifically states: "A vessel engaged in fishing, when at anchor, is considered a vessel engaged in fishing that is **not making way**." Therefore, the signal must be the one designated for a vessel engaged in fishing. According to Rule 35(e): > "A vessel engaged in fishing, when underway or at anchor, shall at intervals of not more than two minutes sound **one prolonged blast followed by two short blasts.**" Therefore, Option C accurately reflects the mandatory fog signal for a vessel engaged in fishing, regardless of whether it is underway or at anchor. *** **Explanation of Incorrect Options:** **A) A rapid ringing of the bell for five seconds at one-minute intervals** * This signal is specified in Rule 35(g) for a **vessel at anchor** (standard anchor signal) of length 100 meters or more. A vessel engaged in fishing has a specific, separate signal (Rule 35(e)) that overrides the standard anchor signal. **B) One prolonged and three short blasts at two-minute intervals** * This signal is specified in Rule 35(d) for a **vessel being towed** (towing vessel). This is not the signal for a vessel engaged in fishing. **D) A sounding of the bell and gong at one-minute intervals** * This is the required additional signal for a vessel at anchor (Rule 35(g)) that is **100 meters or more in length**. It is not the primary signal for a vessel engaged in fishing, which requires the horn blasts.
