Question 12 MODU02 - Barge Supervisor

The Correct Answer is A **Why option A ("take all way off, if necessary") is correct:** This scenario involves restricted visibility (implied by the use of fog signals) and the detection of another vessel forward of the beam, creating a risk of collision. The action required is specifically covered under Rule 19(e) (Conduct of Vessels in Restricted Visibility) of the International Regulations for Preventing Collisions at Sea (COLREGs). Rule 19(e) states that if a vessel determines that a risk of collision exists, or if a close-quarters situation cannot be avoided, she shall take avoiding action in ample time, and: > "If necessary, she shall take all her way off and in any event navigate with extreme caution until the danger of collision is over." Therefore, taking all way off (stopping the vessel relative to the water) is the specific and most critical required action in this dangerous situation. **Why the other options are incorrect:** * **B) stop your engines:** While stopping the engines is the means by which a vessel takes all her way off, Rule 19(e) mandates the effect ("take all her way off") rather than the means ("stop your engines"). More importantly, Rule 19(e) does not strictly forbid the use of engines for short periods if they are needed to control the vessel or maneuver out of danger. Simply stopping the engines without ensuring the vessel loses headway might not be sufficient to satisfy the requirement. Therefore, the stated requirement is the loss of way, not merely stopping the power plant. * **C) begin a radar plot:** Starting a radar plot is a prudent action required under Rule 19(d) *as soon as* a vessel is detected by radar, to determine if risk of collision exists. However, in this question, the risk of collision is already established ("Risk of collision may exist"), and the required action must be an *avoiding* action. A plot is an *assessment* tool, not the mandatory *action* required once danger is confirmed. The mandated action when danger exists is specified in 19(e), which prioritizes reducing speed and taking way off. * **D) All of the above:** Since options B and C are not the specific primary actions required by Rule 19(e) under these circumstances, "All of the above" is incorrect.
