Question 25 RVR04 - Master or Mate of LT 200 GRT

The Correct Answer is D **Why option D ("bare steerageway") is correct:** The scenario described is a specific requirement under the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 19(e) regarding the conduct of vessels in restricted visibility. Rule 19(e) states: "Except where it has been determined that a risk of collision does not exist, 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 her beam, shall reduce her speed to **the minimum at which she can be kept on her course (bare steerageway)**. She shall if necessary take all her way off and in any event navigate with extreme caution until the danger of collision is over." **Why each of the other options is incorrect:** * **A) moderate speed:** This term is too vague and generally implies a speed less than full speed, but still substantial. It does not meet the legal requirement to reduce speed to the minimum necessary for control. * **B) half speed:** This is a specific engine order but may still be too fast. Depending on the vessel and conditions, "half speed" could be much faster than bare steerageway and would violate Rule 19(e). * **C) safe speed:** While all vessels must proceed at a safe speed in restricted visibility (Rule 19(b)), the hearing of a fog signal forward of the beam when risk of collision is undetermined triggers a stricter requirement for speed reduction, specifically down to bare steerageway (Rule 19(e)). Safe speed is a general requirement; bare steerageway is the specific minimum required in this dangerous situation.
