Question 35 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is B **Explanation for Option B (More than two vessels crossing):** The question refers to "special circumstances" under the Rules (specifically the International Regulations for Preventing Collisions at Sea – COLREGs, which apply both internationally and in inland waters unless superseded by local rules). Rule 2 (Responsibility) requires mariners to pay due regard to "any special circumstances, including the limitations of the vessels involved, which may make a departure from these Rules necessary to avoid immediate danger." While Rule 15 covers the basic crossing situation (two vessels), situations involving **three or more vessels interacting simultaneously** (such as three vessels crossing paths near a junction) are generally recognized as "special circumstances." The standard rules (like giving way or standing on) are structured for two-vessel encounters; when multiple vessels create complex, immediate dangers that the standard rules do not adequately cover, the responsibility under Rule 2 dictates that action based on special circumstances must be taken to avoid collision. **Explanation for Incorrect Options:** * **A) Speed in fog (Option A):** Speed in restricted visibility (like fog) is specifically covered by Rule 6 (Safe Speed) and Rule 19 (Conduct of Vessels in Restricted Visibility). While speed must be safe and appropriate, the *concept* of restricted visibility and speed is a rule-mandated requirement, not a "special circumstance" requiring departure from the rules themselves. * **C) Two vessels meeting (Option C):** This scenario is explicitly and directly covered by Rule 14 (Head-on Situation). It is a standard situation for which a rule exists, thus it is not a "special circumstance" requiring a Rule 2 justification. * **D) Vessel at anchor (Option D):** A vessel at anchor is specifically covered by rules regarding anchoring lights/shapes (Rule 30) and general responsibility (Rule 5, 7, 8). While proximity to anchored vessels might require caution, the mere state of being anchored is a standard condition handled by specific rules, not a "special circumstance" justifying departure from the Rules.
