Question 5 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is C **Explanation for Option C (Correct):** Option C, "the nature of her work," is the correct answer. The definition of a vessel "restricted in her ability to maneuver" (RAM) is explicitly laid out in Rule 3(g) and Rule 18(d) of the International Regulations for Preventing Collisions at Sea (COLREGs). These Rules define a RAM vessel as one that, due to the **nature of her operation** (e.g., laying, servicing, or picking up a navigation mark; dredging; surveying; underwater operations; replenishment underway), is constrained in her ability to deviate from her course and is therefore unable to keep out of the way of another vessel. This status grants her special privileges and responsibilities under the Rules. **Explanation of Incorrect Options:** **A) her draft:** This describes a "vessel constrained by her draft" (CBD), defined in Rule 3(h). While a CBD vessel is also restricted in maneuverability, it is a separate and distinct category from a vessel "restricted in her ability to maneuver" (RAM). The limitation for a CBD vessel is physical (the relation between her draft and the available depth and width of the navigable water), not operational (the nature of her work). **B) some exceptional circumstances:** While vessels might be temporarily unable to maneuver due to exceptional circumstances (e.g., mechanical failure, extreme weather), this usually falls under the category of a vessel "not under command" (NUC) (Rule 3(f)), not a vessel "restricted in her ability to maneuver" (RAM). A RAM vessel's inability to maneuver is a planned and inherent part of her designated operation. **D) a danger of navigation:** This is too vague and does not define the statutory status of a RAM vessel. While navigation dangers might cause any vessel to alter course or stop, the RAM status is defined by the operational task being performed (the nature of her work), which systematically prevents her from taking the actions required by the Steering and Sailing Rules.
