Question 27 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is A **Explanation for Option A (power-driven vessel):** The question refers to the basic rules of precedence outlined in the COLREGs (International Regulations for Preventing Collisions at Sea), specifically Rule 18 (Responsibilities between vessels). Rule 18(a) establishes the hierarchy for power-driven vessels underway. A sailing vessel is generally considered more maneuverable than certain other types of vessels, but within the hierarchy, a **power-driven vessel must keep out of the way of a sailing vessel** (Rule 18(a)(iv)). Therefore, a sailing vessel is **NOT required** to keep out of the way of a power-driven vessel. **Explanation of Incorrect Options:** * **B) vessel restricted in her ability to maneuver (RAM):** According to Rule 18(b)(i), a sailing vessel must keep out of the way of a RAM vessel. * **C) vessel engaged in fishing:** According to Rule 18(b)(ii), a sailing vessel must keep out of the way of a vessel engaged in fishing. * **D) vessel not under command (NUC):** According to Rule 18(b)(i), a sailing vessel must keep out of the way of a NUC vessel, as vessels not under command sit at the top of the maneuverability hierarchy.
