Question 5 TV01 - Towing Vessels - Oceans or Near Coastal

The Correct Answer is C **Explanation for C ("the nature of her work"):** The definition of a "vessel restricted in her ability to maneuver" is explicitly provided in the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 3(g). This rule defines such a vessel as one which, **from the nature of her work**, is restricted in her ability to maneuver as required by these Rules and is therefore unable to keep out of the way of another vessel. Examples include vessels engaged in laying, servicing, or picking up a navigation mark, submarine cable, or pipeline; dredging; surveying; transferring persons or provisions while underway; and launching or recovering aircraft. Therefore, the inability to keep out of the way stems directly from the requirements of the task being performed. **Why other options are incorrect:** * **A) her draft:** A vessel restricted by her draft (a "vessel constrained by her draft" under COLREGs Rule 3(h)) is a separate category of vessel. While she is also unable to deviate from her course due to depth limitations, the definition of a *vessel restricted in her ability to maneuver* does not use draft as the defining characteristic. * **B) some exceptional circumstances:** While exceptional circumstances could lead to a vessel becoming "not under command" (Rule 3(f)—e.g., machinery failure), they do not define a vessel as "restricted in her ability to maneuver." The latter classification is based on ongoing, intentional operational activities (work). * **D) a danger of navigation:** This phrase is too vague and general. Specific dangers (like ice, heavy weather, or confined waters) might impact a vessel’s handling, but they do not automatically classify the vessel as "restricted in her ability to maneuver" under the strict definition provided by the COLREGs.
