Question 47 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is D **Explanation for Option D (a risk of collision exists):** This scenario is the classic definition of when a risk of collision exists according to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 7 (Risk of Collision). Rule 7(a)(i) states that such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change. If an approaching vessel is on a steady bearing, it means that if both vessels maintain their course and speed, they are on a collision course, regardless of the distance. **Explanation of Incorrect Options:** **A) a special circumstances situation exists:** While a collision risk might eventually require action under Rule 2 (Responsibility) or Rule 18 (Responsibilities between vessels) which covers 'special circumstances' not explicitly detailed elsewhere, the *immediate* indication of a steady bearing is the risk of collision itself, not the specific maneuver that might follow. Special circumstances apply when standard rules cannot be followed due to conditions (e.g., restricted maneuvering, specific hazards). **B) you are the stand-on vessel:** The fact that a collision risk exists (steady bearing) does not automatically determine which vessel is the stand-on or give-way vessel. Determining stand-on status requires applying other rules (like Rule 13 - Overtaking, Rule 14 - Head-on, or Rule 15 - Crossing Situation). The unchanging bearing only confirms the *existence* of danger, not the responsibilities of the parties involved. **C) the other vessel is dead in the water:** If the other vessel were dead in the water (not moving), your vessel would still show a bearing change unless you were heading directly at it and were the only vessel moving. In most scenarios, if both vessels are approaching, the non-changing bearing indicates relative movement directly toward a common point, not that one vessel is stationary.
