Question 5 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is C **Explanation for Option C (Correct):** The definition of a vessel "restricted in her ability to maneuver" (RAM) is explicitly defined in Rule 3(g) of the International Regulations for Preventing Collisions at Sea (COLREGs) and the corresponding Inland Rules. This definition states that a vessel is unable to maneuver as required by the rules *due to the nature of her work*. Examples of such work include laying or servicing a navigation mark, dredging, underwater operations, fueling or transferring provisions while underway, etc. Therefore, the **nature of her work** is the defining characteristic that places a vessel in the RAM category and grants her specific right-of-way privileges and responsibilities. **Explanation for Option A (Incorrect):** A vessel restricted by her draft (e.g., in a narrow channel) is a separate category defined in Rule 28 (Rule 3(h) in COLREGs). While a vessel constrained by draft has limited maneuverability, this is due to the lack of available water depth and width, not necessarily the *nature of her work*. The term "restricted in her ability to maneuver" specifically refers to the work-related limitations. **Explanation for Option B (Incorrect):** "Exceptional circumstances" is a general term and does not define the statutory status of a "restricted in her ability to maneuver" vessel. While a vessel may encounter exceptional circumstances that temporarily limit its movement, the RAM classification requires that the limitation is due to the inherent work being performed. **Explanation for Option D (Incorrect):** A "danger of navigation" (or a navigational hazard) might cause any vessel to change course or slow down, but it does not define the operational status of a vessel as being "restricted in her ability to maneuver." If a vessel is responding to a sudden danger, she may be designated as a "vessel not under command" (Rule 3(f)), which is a different category altogether, or simply executing emergency action under Rule 2 (Responsibility).
