Question 4 ONC07 - OUPV-Near Coastal

The Correct Answer is B A **Vessel restricted in her ability to maneuver (RAM)** is defined in Rule 3(g) of the International Regulations for Preventing Collisions at Sea (COLREGs) as a vessel which, from the nature of her work, is unable to keep out of the way of another vessel. This is the official definition used in both the International and Inland Rules. COLREGs also assign specific hierarchy of responsibility (Rules 18(a) and 18(b)) which prioritize vessels that are restricted in their ability to maneuver above all other types listed in the options (towing, fishing, and sailing vessels) because they are, by definition, unable to comply with the normal requirement to keep clear. **Why the other options are incorrect:** * **A) Vessel towing:** A vessel towing is generally a "power-driven vessel" (PDV). While a tow severely limits mobility, a vessel towing is generally required to keep out of the way of a Vessel Restricted in her Ability to Maneuver, a Vessel Engaged in Fishing, and a Sailing Vessel (Rule 18). Therefore, she is still defined as able to keep out of the way of certain vessels. * **C) Vessel engaged in fishing:** A vessel engaged in fishing is required to keep out of the way of a Vessel Not Under Command and a Vessel Restricted in her Ability to Maneuver (Rule 18). She is therefore defined as able to keep out of the way of certain vessels (like PDVs and sailing vessels). * **D) Sailing vessel:** A sailing vessel is generally required to keep out of the way of a Vessel Not Under Command, a Vessel Restricted in her Ability to Maneuver, and a Vessel Engaged in Fishing (Rule 18). Therefore, she is still defined as able to keep out of the way of certain vessels (like power-driven vessels).
