Question 35 RVR04 - Master or Mate of LT 200 GRT

The Correct Answer is B **Explanation for B (More than two vessels crossing):** The term "special circumstance" under the International Regulations for Preventing Collisions at Sea (COLREGs) and Inland Rules refers to situations not explicitly or adequately covered by the standard steering and sailing rules (Parts B and C), which require mariners to depart from the Rules to avoid immediate danger (Rule 2 - Responsibility). While the rules cover "crossing situations" (two vessels crossing, Rule 15), they do not explicitly detail the rights and responsibilities when *more than two* vessels are involved in a close-quarters crossing or meeting scenario simultaneously. A situation involving multiple vessels (e.g., three or more) engaged in crossing maneuvers creates an extremely complex and hazardous situation that demands caution, good seamanship, and may necessitate the involved vessels taking action outside the standard "give-way" or "stand-on" mandates to ensure safety. Therefore, the complexity arising from three or more vessels interacting closely is often treated as a "special circumstance" requiring flexible application of Rule 2 to prevent collision. **Why the other options are incorrect:** * **A) Speed in fog:** Speed in restricted visibility (fog) is directly and explicitly addressed by Rule 19 (Conduct of Vessels in Restricted Visibility). Following Rule 19 regarding safe speed and taking early action is standard procedure, not a special circumstance requiring deviation from the rules. * **C) Two vessels meeting:** This is a fundamental scenario explicitly covered by Rule 14 (Head-on Situation). The rules clearly dictate how two vessels meeting end-on must pass each other (both altering course to starboard). This is a standard rule application. * **D) Vessel at anchor:** A vessel at anchor is considered a vessel "not under command" for the purpose of maneuvering risk, and their required lights, shapes, and conduct are explicitly detailed in Rule 30 (Vessels at Anchor and Vessels Aground). This is a standard status under the Rules, not a special circumstance.
