Question 5 GLI07 - OUPV

The Correct Answer is C **Why option C ("the nature of her work") is correct:** The definition and obligations of a vessel "restricted in her ability to maneuver" (RAM) are codified in the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 3(g) and Rule 18. A vessel becomes legally designated as RAM when, **by the nature of her work**, she is unable to deviate from her course or keep out of the way of another vessel. Examples of such work include laying or servicing a navigation mark, dredging, surveying, underwater operations, or certain fishing operations. This designation is based on the functional necessity imposed by the activity she is engaged in. **Why the other options are incorrect:** * **A) her draft (A vessel constrained by her draft):** While a deep-draft vessel may be restricted in her ability to maneuver, COLREGs define "A vessel constrained by her draft" (CBD) separately under Rule 3(h). This is a distinct category with specific rules that apply only to vessels that cannot safely deviate from their course due to their depth relative to the available navigable water. It is not the definition of a vessel "restricted in her ability to maneuver" (RAM). * **B) some exceptional circumstances:** This phrase is too broad and does not align with the formal COLREGs definition. "Exceptional circumstances" could refer to a sudden emergency or breakdown (which would relate to a vessel "not under command," Rule 3(f)), but the RAM designation is based on an ongoing, planned restriction due to the type of work being performed. * **D) a danger of navigation:** This is a general term describing a potential hazard (e.g., a shallow area, a wreck, or adverse weather) and does not define the reason why a specific vessel is categorized as "restricted in her ability to maneuver." If a vessel is facing a danger of navigation, her reaction may fall under other rules (like Rule 2, Responsibility) but the definition of RAM itself is tied to the work she is doing.
