Question 15 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is A ### Explanation of Option A (Correct) Option A, "Neither vessel is the stand-on vessel," is correct because the rules regarding stand-on and give-way vessels (Rules 12 through 18, including the Crossing Rule, Rule 15) apply only when vessels are **in sight** of one another. When vessels are crossing in restricted visibility (fog) and are **not in sight**, the governing rule is Rule 19 (Conduct of Vessels in Restricted Visibility). Rule 19 mandates that both vessels act cautiously, typically involving reducing speed to minimum steerageway (Rule 19(e)) or taking appropriate avoiding action. The specific designation of "stand-on" vessel does not apply under these conditions; both vessels are responsible for taking action to avoid collision. ### Explanation of Other Options (Incorrect) **B) The vessel which hears the other vessel's fog signal first** This is incorrect. The sequence in which signals are heard has no bearing on collision avoidance responsibilities or the designation of stand-on/give-way status. Hearing a signal merely confirms the presence of the other vessel, triggering the cautious actions required by Rule 19(e). **C) The vessel which has the other on her own starboard side** This describes the **give-way** vessel under the normal Crossing Rule (Rule 15). Furthermore, Rule 15 only applies when vessels are in sight. Since they are not in sight, the normal crossing rules are superseded by Rule 19, making the designation irrelevant. **D) The vessel which has the other on her own port side** This describes the **stand-on** vessel under the normal Crossing Rule (Rule 15). As explained above, because the vessels are not in sight, Rule 15 does not apply. Rule 19 governs the situation, requiring cautious action from both vessels, thus making this vessel designation incorrect.
