Question 35 RVR05 - Master of LT 100 GRT

The Correct Answer is B **Explanation for B (More than two vessels crossing):** Option B, "More than two vessels crossing," is considered a "special circumstance" under Rule 2 (Responsibility) and Rule 18 (Responsibilities between Vessels) of the COLREGs (Convention on the International Regulations for Preventing Collisions at Sea). The Rules explicitly define responsibilities (give-way/stand-on) for **two** vessels crossing, meeting, or overtaking. When three or more vessels are interacting in a manner that creates immediate danger of collision (especially crossing), the simple two-vessel rules often become inadequate, overly complex, or contradictory. In such a scenario, the master must depart from specific rules to avoid immediate danger, relying instead on the general requirement of good seamanship and prudence, which falls under the definition of a "special circumstance." **Why the other options are incorrect:** * **A) Speed in fog:** While speed in restricted visibility (fog) is governed by Rule 6 (Safe Speed) and Rule 19 (Conduct of Vessels in Restricted Visibility), setting an unsafe speed is a violation of a specific rule, not a "special circumstance" that necessitates departure from the rules. Rule 19 provides the guidance on how to act in fog. * **C) Two vessels meeting:** This is the most common encounter and is specifically and clearly addressed by Rule 14 (Head-on Situation). It is a standard scenario governed by a specific rule, not a circumstance requiring special action outside the defined rules. * **D) Vessel at anchor:** A vessel at anchor is considered a non-moving vessel and its status is covered by Rule 30 (Vessels at Anchor and Vessels Aground) regarding lights and shapes. It is a defined status under the Rules, not an unpredictable or complex situation requiring the invocation of "special circumstances."
