Question 31 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is A **Explanation for Option A (Correct):** Option A, "Assist in taking whatever action is necessary to avoid collision," is correct because it directly reflects the principle of the "General Prudential Rule" (Rule 2) and the actions required when a collision is imminent. Under both the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Rules, while one vessel is designated the "stand-on" vessel, this designation does not absolve it of its duty to avoid a collision. Specifically, Rule 17(b) states that when it becomes apparent that the give-way vessel is not taking appropriate action, the stand-on vessel **must** take action to avoid collision. Furthermore, Rule 17(c) dictates that when, for any reason, the stand-on vessel finds herself so close that collision cannot be avoided by the action of the give-way vessel alone, she **shall** take such action as will best aid to avert collision. In immediate danger, both vessels must cooperate to prevent the accident. **Explanation for Other Options (Incorrect):** * **B) Abandon ship:** This is an extreme measure taken only after a major incident has occurred or a collision is unavoidable and imminent, not the primary action required to prevent the collision itself. The immediate duty is to try and avert the danger. * **C) Hold course and speed until the danger of collision is past and clear:** This is the stand-on vessel’s general requirement (Rule 17(a)(i)) in a normal crossing or overtaking situation. However, this duty ceases when immediate danger of collision exists. As specified in Rule 17(b) and (c), the stand-on vessel must take action when the danger is immediate or apparent, making holding course and speed the incorrect action when danger is critical. * **D) Sound a distress signal:** A distress signal is used to alert others that a vessel is in grave and imminent danger and requires assistance. While a vessel in immediate danger of collision is certainly in distress, sounding a signal does nothing to physically prevent the collision. The primary duty is to take physical maneuvering action (Option A).
