Question 4 GLI01 - Master-Unlimited Tonnage

The Correct Answer is B **Explanation for Option B (Vessel restricted in her ability to maneuver):** Option B is correct because the International Regulations for Preventing Collisions at Sea (COLREGs), which apply both internationally and in many adapted inland rules (Rule 1, Rule 3), specifically define a vessel restricted in her ability to maneuver (RAM) in Rule 3(g) as: > "A vessel which from the nature of her work is **unable** to keep out of the way of another vessel." This legal definition directly answers the question, establishing that the vessel's operational constraint makes it legally and practically incapable of taking avoiding action. *** **Explanation of Incorrect Options:** **A) Vessel towing:** A vessel engaged in towing is certainly constrained, but it is not defined as being *unable* to keep out of the way. It is expected to maneuver to avoid collision when required, particularly when encountering a vessel Not Under Command (NUC) or a vessel Restricted in Her Ability to Maneuver (RAM). **C) Vessel engaged in fishing:** A vessel engaged in fishing is restricted by its gear and has priority over power-driven vessels and sailing vessels. However, Rule 18 still requires a fishing vessel to keep out of the way of a vessel NUC and a vessel RAM. Therefore, it is *restricted* but not legally *unable* to maneuver out of the way of all other vessels. **D) Sailing vessel:** A sailing vessel is fully expected to maneuver and is required to keep out of the way of vessels NUC, RAM, and vessels engaged in fishing. While it has priority over a power-driven vessel, it is not considered constrained to the point of being unable to avoid other traffic.
