Question 12 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is A Option A ("take all way off, if necessary") is correct because it directly reflects the requirements of Rule 19(e) of the International Regulations for Preventing Collisions at Sea (COLREGS), which governs the conduct of vessels in restricted visibility. Rule 19(e) states that if a vessel detects the presence of another vessel forward of the beam and a risk of collision exists, it shall take appropriate action, which *shall include* "reducing her speed to a minimum and if necessary taking all her way off." This is the primary mandated action to be taken under these specific circumstances. ### Why the other options are incorrect: **B) stop your engines:** While reducing speed and potentially stopping the vessel usually involves stopping the engines, Rule 19(e) specifically mandates reducing speed to a minimum and taking all way off. Stopping the engines is a *means* to achieve the required action (taking all way off), but it is not the *only* required action, nor is it the specific primary action mandated by the Rule (which is reducing speed/taking way off). A vessel might need to keep engines ticking over or use them for slight maneuvers even while taking all way off. **C) begin a radar plot:** Radar plotting is a standard and recommended practice when navigating in restricted visibility and is essential for determining risk of collision (Rule 19(d) discusses obtaining early warning and systematically observing targets). However, once the risk of collision is confirmed and the fog signal is heard forward of the beam, the immediate requirement of Rule 19(e) takes precedence: reducing speed and taking all way off. Radar plotting is an action of *assessment* and *planning*, but not the mandatory immediate *collision avoidance maneuver* required by the rule when risk is present and the vessel is forward of the beam. **D) All of the above:** Since options B and C are not the specific primary mandatory requirement set forth in Rule 19(e), this option is incorrect.
