Question 12 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is A Option A, "take all way off, if necessary," is correct because it directly addresses the requirement mandated by Rule 19 (Conduct of Vessels in Restricted Visibility), specifically paragraph (e). 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 a minimum at which she can be kept on her course. If necessary, she shall take all her way off and in any event navigate with extreme caution until danger of collision is over." Therefore, taking all way off is a mandatory action under the described circumstances if speed reduction alone is insufficient to meet the requirement of navigating safely until the danger passes. Here is why the other options are incorrect: * **B) stop your engines:** While reducing speed and taking all way off might involve stopping the engines, the *specific mandatory action* required by Rule 19(e) is to reduce speed to a minimum and, if necessary, take all way off. Simply stopping the engines without addressing the vessel's way (momentum) does not satisfy the primary requirement of taking all way off and navigating with extreme caution. The rule prioritizes the elimination of forward movement when necessary, not just the stopping of propulsion. * **C) begin a radar plot:** While prudent seamanship in restricted visibility certainly involves the use of radar and potentially plotting (Rule 19(d)), the immediate, non-discretionary action required *upon hearing a fog signal forward of the beam* is the reduction of speed and/or taking all way off (Rule 19(e)). Radar plotting is a necessary ongoing navigational duty, but it is not the **required action** that directly addresses the immediate danger signaled by the fog horn under Rule 19(e). * **D) All of the above:** Since options B and C are not the primary, mandated actions under Rule 19(e), this option is incorrect.
