Question 4 OSV01 - Master/Chief Mate - Offshore Supply Vessels

The Correct Answer is B A **Vessel restricted in her ability to maneuver (RAM)** is defined in Rule 3(g) of both the International Regulations for Preventing Collisions at Sea (COLREGs) and the Inland Rules as a vessel which, from the nature of her work, is **unable to keep out of the way of another vessel**. This inability is inherent to the definition and justifies her privileged status as per Rule 18(b). Here is why the other options are incorrect: * **A) Vessel towing:** A vessel towing is generally a power-driven vessel and is normally required to keep out of the way of many other vessels (such as sailing vessels, fishing vessels, and RAMs), unless she is constrained by her draft (CBD) or restricted in her ability to maneuver (RAM), which are separate categories. She is generally **able** to keep out of the way. * **C) Vessel engaged in fishing:** A vessel engaged in fishing is generally required to keep out of the way of a RAM or a CBD. While her nets or gear may restrict her movement, the definition in Rule 3 does not state that she is unable to keep out of the way of *another vessel*; rather, she is simply required to give way to vessels that are even more constrained (like RAMs). * **D) Sailing vessel:** A sailing vessel is often a burdened vessel required to keep out of the way of other sailing vessels (depending on the tack), a fishing vessel, or a RAM. She is generally **able** to maneuver and keep out of the way.
