Question 4 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is B A **Vessel restricted in her ability to maneuver (RAM)** is defined in Rule 3(g) of the International Regulations for Preventing Collisions at Sea (COLREGs) as a vessel that, *from the nature of her work*, is unable to maneuver as required by the Rules and is therefore unable to keep out of the way of another vessel. This definition directly implies that the vessel is unable to take the action necessary to avoid collision, making it the highest priority category of "unable to keep out of the way" vessels (after a NUC vessel, which is entirely disabled). --- **Why the other options are incorrect:** A) **Vessel towing:** A vessel towing is generally a power-driven vessel. Although she may be hampered by her tow (Rule 24), she is still capable of maneuvering and is required to keep out of the way of certain vessels (such as a NUC, RAM, or fishing vessel). She is not defined as being *unable* to keep out of the way. C) **Vessel engaged in fishing:** A vessel engaged in fishing is *required* by Rule 18(b)(i) to keep out of the way of a Vessel Not Under Command (NUC) and a Vessel Restricted in Her Ability to Maneuver (RAM). Therefore, she is capable of keeping out of the way of other vessels and is not defined as being unable to do so. D) **Sailing vessel:** A sailing vessel is required by Rule 12 and Rule 18(a)(iii) to keep out of the way of NUC, RAM, and fishing vessels. In a crossing or overtaking situation with a power-driven vessel, she is generally the stand-on vessel, but she is fully capable of taking avoiding action if required (e.g., if the other vessel is unable to keep out of the way, or if action is necessary to avoid immediate danger). She is not defined as being unable to keep out of the way.
