Question 14 RVR01 - Master of Unlimited Tonnage

The Correct Answer is B **Explanation of B (Correct Option):** Option B states: "Your vessel is the give-way vessel in a crossing situation." The scenario describes a power-driven vessel that is stopped and making no way but is not disabled. The vessel is approached by another vessel on its starboard beam. Under the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 15 defines a crossing situation between two power-driven vessels. Rule 15 states that when two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way (i.e., is the give-way vessel). Since the other vessel is approaching on your starboard beam, your vessel is the one that has the other vessel on its starboard side. Your vessel is still considered a power-driven vessel, even though it is stopped and making no way. Therefore, your vessel is the give-way vessel in this crossing situation. **Why Other Options Are Incorrect:** * **A) You should be showing the lights or shapes for a vessel not under command.** * **Incorrect.** A vessel Not Under Command (NUC) is unable to maneuver due to some exceptional circumstance (Rule 3(g)). The scenario explicitly states your vessel "is not in any way disabled." Since you are stopped voluntarily and can restart your engines, you must display the lights/shapes of a power-driven vessel (or, if anchored, an anchored vessel, but here you are merely stopped and "making no way"), not an NUC. * **C) You should be showing the lights or shapes for a vessel restricted in her ability to maneuver.** * **Incorrect.** A vessel Restricted in Her Ability to Maneuver (RAM) is limited in movement due to the nature of its work (e.g., dredging, laying cable, servicing aids to navigation) (Rule 3(h)). Simply being stopped and not making way does not qualify a vessel as RAM; you are still capable of maneuvering. * **D) The other vessel must give-way since your vessel is stopped.** * **Incorrect.** The COLREGs do not provide an exemption or change of status (from power-driven) simply because a vessel is temporarily stopped or making no way. As long as the vessel is operational, it remains a power-driven vessel (Rule 23). Since your vessel has the other vessel on its starboard beam, Rule 15 dictates that your vessel is the give-way vessel, and the other vessel is the stand-on vessel.
