Question 12 GLI01 - Master-Unlimited Tonnage

The Correct Answer is A Option A ("take all way off, if necessary") is correct because it aligns directly with Rule 19(e) (Conduct of vessels in restricted visibility) of the COLREGs (International Regulations for Preventing Collisions at Sea). Rule 19(e) states that if a vessel hears the fog signal of another vessel forward of her beam, or cannot avoid a close-quarters situation with a vessel forward of her beam, she shall reduce her speed to the 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 the danger of collision is over. Taking all way off (stopping headway) is the most conservative and mandatory maneuver when risk of collision exists in restricted visibility and the danger is forward of the beam. **Why the other options are incorrect:** * **B) stop your engines:** While stopping the engines is a common step when taking all way off, Rule 19(e) specifically requires reducing speed to the minimum necessary or taking all way off. Stopping the engines alone (while still having headway) might not be sufficient to fulfill the requirement to take all way off and certainly doesn't encompass the full range of required maneuvers (like holding minimum steerage way). Taking all way off (A) is the more complete and mandated action. * **C) begin a radar plot:** Beginning a radar plot is good seamanship and generally required for proper assessment under Rule 19(d), but it is a required *precursor* or *assessment tool*, not the mandatory *action* required by Rule 19(e) specifically concerning hearing a fog signal forward of the beam and risk of collision existing. The mandatory action is the speed reduction or taking all way off. * **D) All of the above:** Since B and C are not the primary, mandated operational maneuver required by Rule 19(e) (which governs what to do upon hearing the signal), this option is incorrect.
