Question 12 ONC07 - OUPV-Near Coastal

The Correct Answer is A Option A ("take all way off, if necessary") is correct because it directly addresses the requirements of Rule 19(e) (Conduct of Vessels in Restricted Visibility) of the International Regulations for Preventing Collisions at Sea (COLREGs). Rule 19(e) mandates that if a vessel detects the presence of another vessel forward of the beam and believes that a risk of collision exists, it shall take timely action to avoid collision, and "shall in any event reduce her speed to the minimum at which she can be kept on her course." Furthermore, it states that if necessary, she shall take all her way off. This rule is designed for situations where visual cues are lacking, and reducing speed or stopping is the safest immediate measure when risk is detected forward of the beam. **Why the other options are incorrect:** * **B) stop your engines:** While reducing speed and taking all way off might necessitate stopping the engines, Rule 19(e) specifically requires reducing speed to the *minimum at which she can be kept on her course* and, if necessary, taking all way off. Simply stopping the engines (which may not always equate to taking all way off immediately, depending on vessel inertia) is an insufficient and potentially incomplete requirement compared to the comprehensive action required by Rule 19(e). It is the action of reducing or taking off way that is the requirement, not just the mechanical act of stopping the engines. * **C) begin a radar plot:** Radar plotting (required under Rule 7) should be conducted continuously when operating in restricted visibility and using radar. It is a necessary part of determining if a risk of collision exists, but it is not the *required action* to be taken *after* hearing a fog signal forward of the beam and establishing that risk of collision *may exist*. The specific and timely action required in that precise moment, according to Rule 19(e), is speed reduction/taking all way off. * **D) All of the above:** Since options B and C are not the primary, specific, or mandatory actions required by Rule 19(e) in this scenario, this option is incorrect.
