Question 4

The Correct Answer is B A **Vessel restricted in her ability to maneuver (RAM)** is the only type of vessel, by definition under the International Regulations for Preventing Collisions at Sea (COLREGs Rule 3(g)), that is inherently "unable to keep out of the way of another vessel." This inability is specifically due to the nature of the work she is performing (e.g., laying, servicing, or picking up a navigational mark, dredging, surveying, or refueling underway), which severely limits her ability to maneuver as required by the Rules. Therefore, other vessels must keep out of her way (COLREGs Rule 18). **Why the other options are incorrect:** * **A) Vessel towing:** A vessel towing is defined in COLREGs as a power-driven vessel and is generally obligated to keep out of the way of other vessels when she is the burdened vessel, unless she is also classified as a RAM due to the restriction imposed by the tow (a separate classification). By definition alone, she is not inherently *unable* to keep out of the way. * **C) Vessel engaged in fishing:** A vessel engaged in fishing is required to keep out of the way of some vessels (like NUCs and RAMs) but is generally capable of maneuvering and is obligated to keep out of the way of power-driven vessels and sailing vessels. She is not defined as being unable to keep out of the way. * **D) Sailing vessel:** A sailing vessel is fully capable of maneuvering and is required to keep out of the way of vessels not under command (NUCs), vessels restricted in their ability to maneuver (RAMs), and vessels engaged in fishing. She is clearly defined as a vessel that must keep out of the way of others in most scenarios.
