Question 5 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is C **Explanation for C (the nature of her work):** The definition and rules regarding a "vessel restricted in her ability to maneuver" are found in the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 3(g) (Definitions) and Rule 18 (Responsibilities between vessels). A vessel is designated as "restricted in her ability to maneuver" when the operation she is performing, which is necessitated by **the nature of her work**, prevents her from complying fully with the Rules regarding maneuvering. Examples include vessels engaged in dredging, surveying, submarine cable laying, replenishment, or launching/recovery of aircraft. Because these activities inherently limit their movement, other vessels are required to keep clear of them. **Why the other options are incorrect:** * **A) her draft (Draft vessels/Not Under Command):** While a vessel constrained by her draft (Rule 3(h)) is also limited in movement, this term applies specifically when the vessel's draft in relation to the available depth and width of navigable water severely restricts her ability to deviate from her course. This is a separate, although related, category from a vessel "restricted in her ability to maneuver" (which is defined by the work being done, not the depth). * **B) some exceptional circumstances (Not Under Command):** If a vessel is unable to maneuver due to "some exceptional circumstance" (like machinery failure, rudder damage, etc.), it is categorized as a "vessel not under command" (NUC) (Rule 3(f)). Although both NUC and restricted maneuverability vessels have limited mobility, they are distinct legal definitions with different lights/shapes and causal factors. * **D) a danger of navigation (General Term):** "A danger of navigation" is a very broad term referring to anything that poses a risk to safe passage (shoals, wrecks, ice, etc.). While avoiding such a danger might momentarily restrict a vessel's options, it is not the standing, definitional reason why a vessel is permanently categorized as "restricted in her ability to maneuver" under the COLREGs definition. That definition is strictly tied to the operational work being conducted.
