Question 5 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is C **Explanation for Option C (Correct):** Option C, "the nature of her work," is the defining criterion in the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 3(g), for classifying a vessel as "restricted in her ability to maneuver" (RAM). This rule states that a vessel is restricted in her ability to maneuver if, **from the nature of her work**, she is unable to keep out of the way of another vessel. Examples of such work include laying, servicing, or picking up a navigation mark, submarine cable, or pipeline; dredging; surveying; transferring persons or provisions while underway; and mine clearance operations. The inability to maneuver is a temporary and necessary consequence of the specific job being performed. **Why Other Options Are Incorrect:** * **A) her draft:** A vessel constrained by her draft (CBD) is a separate category of vessel defined in Rule 3(h). While a CBD vessel is severely limited in its ability to deviate from its course, its limitation is due to the relationship between its deep draft and the available depth and width of navigable water, not specifically the "nature of her work" that defines a RAM vessel. * **B) some exceptional circumstances:** This phrase is too vague and does not correspond to the specific definition of a RAM vessel. While an exceptional circumstance might cause a temporary breakdown or emergency (which could be covered under a "vessel not under command," or NUC, Rule 3(f)), it is not the reason a vessel is performing work that makes it RAM. * **D) a danger of navigation:** This phrase refers to hazards (such as rocks, shallow water, or wreck) that all vessels must avoid, but it is not the reason a vessel is performing work that restricts its ability to maneuver and qualifies it for the special status under COLREGs Rule 3(g).
