Question 4

The Correct Answer is B A **Vessel restricted in her ability to maneuver (RAM)** is the correct answer because, by definition according to the International Regulations for Preventing Collisions at Sea (COLREGs Rule 3(g)), this type of vessel is one which, **"from the nature of her work, is restricted in her ability to maneuver as required by these Rules and is therefore unable to keep out of the way of another vessel."** This inability is explicitly built into the definition of the category, granting her special rights and responsibilities (such as displaying specific lights/shapes) under both the International and Inland Rules. **Why the other options are incorrect:** * **A) Vessel towing:** A vessel towing is generally a "power-driven vessel" and, while her ability to maneuver may be hampered, she is **not** defined as being "unable" to keep out of the way. She has a duty to keep clear of vessels like RAMs, fishing vessels, and sailing vessels. * **C) Vessel engaged in fishing:** A vessel engaged in fishing is required to keep out of the way of vessels that are Not Under Command (NUC) or Restricted in her Ability to Maneuver (RAM). Although limited by nets/lines, she is **not** inherently defined as unable to keep out of the way of all other vessels. * **D) Sailing vessel:** A sailing vessel must keep out of the way of NUCs and RAMs. She has a much greater degree of maneuverability than a RAM and is fully capable of keeping out of the way of another vessel (such as a fishing vessel or another sailing vessel).
