Question 5 ONC06 - Master 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) under the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 3(g) and Rule 18, explicitly states that such a vessel, by the **nature of her work**, is unable to keep out of the way of another vessel. This status is granted to vessels engaged in specific activities (such as dredging, surveying, submarine cable laying, etc.) where the equipment or process necessary for the work physically prevents them from deviating from their course or maneuvering readily. **Why other options are incorrect:** * **A) her draft (Incorrect):** A vessel constrained by her draft (CBD) is a separate category of vessel under COLREGs (Rule 3(h) and Rule 18) that is restricted due to the relationship between its deep draft and the available depth and width of navigable water. While a CBD vessel is also restricted in its maneuverability, the term "restricted in her ability to maneuver" (RAM) refers specifically to the limitations imposed by the **nature of the work**, not the physical dimensions relative to the waterway depth. * **B) some exceptional circumstances (Incorrect):** While unusual situations can restrict a vessel's movement (e.g., equipment failure leading to "not under command" status), "exceptional circumstances" is too vague and does not define the statutory category of a vessel "restricted in her ability to maneuver." The RAM status is based on the deliberate operational activity. * **D) a danger of navigation (Incorrect):** This phrase describes a hazard (like a shoal, wreck, or strong current). While navigating near such dangers can influence maneuvering, it is a navigational consideration, not the reason a vessel is legally defined as "restricted in her ability to maneuver" according to COLREGs.
