Question 12 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is A **Why option A ("take all way off, if necessary") is correct:** This question references the Rules of the Road (COLREGs), specifically Rule 19, which covers the conduct of vessels in restricted visibility (such as fog). Rule 19(e) states the requirements for a vessel hearing a fog signal forward of her beam, indicating the presence of another vessel whose close quarters situation cannot be avoided: > "Any 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. She shall if necessary take all her way off and in any event navigate with extreme caution until danger of collision is over." Therefore, the requirement to "take all way off, if necessary" is a mandatory action under COLREGs Rule 19(e) when hearing a fog signal forward of the beam and risk of collision may exist. **Why the other options are incorrect:** * **B) stop your engines:** While a vessel might stop the engines to take all way off (Option A), the direct and mandatory requirement listed in Rule 19(e) is to reduce speed to a minimum and, if necessary, take all way off. Stopping the engines is a means to achieve the required reduction in speed or loss of way, but it is not the primary required action itself. Moreover, simply stopping the engines while still carrying significant momentum does not immediately fulfill the requirement to take all way off. * **C) begin a radar plot:** Radar plotting (or equivalent systematic observation of detected targets) is generally required when operating in restricted visibility and a target is detected (Rule 19(d)). However, the specific *immediate* action mandated by Rule 19(e) upon hearing a fog signal forward of the beam and facing possible risk of collision is the speed reduction/loss of way. While prudent seamanship involves plotting, the required rule-based action specific to the situation described is taking all way off. * **D) All of the above:** Since options B and C are not the primary, mandatory actions required by Rule 19(e) for this specific scenario (hearing the fog signal forward of the beam), this option is incorrect.
