Question 48 MODU02 - Barge Supervisor

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 (RAM) or a vessel **at anchor** in a restricted area, *if it is required to make a sound signal other than that of an ordinary vessel at anchor*. In the specific scenario presented: "A vessel engaged in fishing **while at anchor**," the vessel is subject to Rule 35(c) of the International Regulations for Preventing Collisions at Sea (COLREGs). 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 at intervals of not more than two minutes sound **one prolonged followed by two short blasts**. Since a vessel engaged in fishing is required to sound this specific signal (Rule 35(c)), this signal takes precedence over the standard signal for a vessel at anchor (Rule 35(g)). **Explanation of Incorrect Options:** **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)) under 100 meters in length. However, the vessel in the question is also "engaged in fishing," which mandates the use of the specific signal prescribed in Rule 35(c) (one prolonged and two short blasts). **B) One prolonged and three short blasts at two-minute intervals:** This signal is designated for a vessel being towed (Rule 35(e)), or the last vessel in a tow. It does not apply to a vessel engaged in fishing. **D) A sounding of the bell and gong at one-minute intervals:** This is the fog signal for a vessel **at anchor** 100 meters or more in length (Rule 35(g)). As explained above, the "engaged in fishing" status requires the use of the Rule 35(c) signal instead.
