Question 25 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is D **Explanation for Option D (bare steerageway):** The scenario described—a vessel hearing a fog signal forward of her beam without having determined if risk of collision exists—is directly addressed by Rule 19(e) (Conduct of Vessels in Restricted Visibility) of the International Regulations for Preventing Collisions at Sea (COLREGs). Rule 19(e) mandates that every vessel which hears, apparently forward of her beam, the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of the beam, **shall reduce her speed to the minimum at which she can be kept on her course (i.e., bare steerageway)**. If necessary, she shall take all her way off and, in any event, navigate with extreme caution until danger of collision is over. **Explanation of Why Other Options Are Incorrect:** * **A) moderate speed:** While a moderate speed is generally required in restricted visibility (Rule 19(b)), once a specific danger (hearing a fog signal forward of the beam) arises, the required action is to reduce speed drastically to the minimum necessary for control (bare steerageway), not merely a moderate speed. * **B) half speed:** "Half speed" is an arbitrary setting and does not align with the regulatory requirement to reduce speed to the minimum necessary for control ("bare steerageway"). Half speed might still be excessive in fog when danger is imminent. * **C) safe speed:** A "safe speed" (Rule 6) is always required, especially in restricted visibility (Rule 19(b)). However, when a vessel hears a fog signal forward of the beam, the specific, required action is even more cautious than maintaining a general safe speed; it is to reduce speed to **bare steerageway**. Bare steerageway is the definitive term for the lowest speed required in this critical situation.
