Question 12 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is A. **Explanation for A (Correct Option):** Option A, "take all way off, if necessary," is the correct answer because it directly reflects the requirements of Rule 19(e) (Conduct of Vessels in Restricted Visibility). This rule governs vessel behavior when hearing a fog signal forward of the beam and when a risk of collision exists (or cannot be avoided). Rule 19(e) explicitly mandates that any vessel that detects the presence of another vessel forward of the beam must reduce its speed to a minimum and, "if necessary, take all her way off and in any event navigate with extreme caution until danger of collision is over." This action prioritizes safety and gives the operator maximum time to assess the situation and avoid collision. **Explanation of Incorrect Options:** * **B) stop your engines:** While reducing speed is mandatory, the requirement is to reduce speed to minimum steerage way or take all way off. Simply stopping the engines (which may still leave the vessel moving significantly, depending on inertia) is not the specific, required action. Furthermore, stopping the engines entirely might leave the vessel without immediate maneuverability (steerage way), which can be dangerous. Taking all way off ("if necessary") is the specific regulatory instruction. * **C) begin a radar plot:** While prudent seamanship in restricted visibility certainly involves monitoring radar, Rule 19(e) specifies actions related to speed and movement *upon hearing* the fog signal. Beginning a radar plot (or using radar) is a mandatory part of safe navigation under Rule 19(d) when operating in restricted visibility, but it is not the **required action** stipulated by Rule 19(e) for the specific scenario of hearing a fog signal forward of the beam with existing risk. The immediate, legally required maneuver is managing the vessel's speed. * **D) All of the above:** Since options B and C are not the primary, required action under Rule 19(e) for this specific scenario, this option is incorrect.
