Question 5 GLI01 - Master-Unlimited Tonnage

The Correct Answer is C **Explanation for Option C (Correct Answer):** Option C, "the nature of her work," is the correct answer because it directly reflects the definition and status of a "vessel restricted in her ability to maneuver" (RAM) as defined in Rule 3(g) and Rule 18(a)(ii) of the International Regulations for Preventing Collisions at Sea (COLREGs) (which applies to both International and Inland waters, as stipulated in the question). A RAM vessel is one that, by the nature of its operation—such as dredging, surveying, submarine cable laying, or launching/recovering aircraft—is constrained and therefore unable to deviate from its course or keep out of the way of another vessel as required by the Rules. This inability is inherent to the type of work being performed. **Why the Other Options are Incorrect:** * **A) her draft:** This describes a "vessel constrained by her draft" (CBD), which is a separate category defined in Rule 3(h). While a CBD vessel is also limited in its ability to maneuver, it is restricted by the physical relationship between its deep draft and the available depth and width of the navigable water. It is not the definition of a vessel "restricted in her ability to maneuver" (RAM). * **B) some exceptional circumstances:** While exceptional circumstances could temporarily limit any vessel's maneuvering ability (e.g., machinery breakdown), this phrase is too broad and does not specifically define the *status* of a vessel that is recognized and protected under COLREGs as "restricted in her ability to maneuver." The RAM status is defined by the ongoing nature of the work, not a temporary, exceptional event. * **D) a danger of navigation:** This describes a situation where a vessel might take action to avoid immediate peril (e.g., following Rule 2, the General Prudential Rule), but it is not the defining reason why a vessel is given the specialized status and hierarchy of a "vessel restricted in her ability to maneuver" under the Rules.
