Question 4 ONC03 - Master LT 500-1600 GRT

The Correct Answer is B **Explanation for Option B (Vessel restricted in her ability to maneuver):** Option B is correct because the entire definition of a Vessel Restricted in her Ability to Maneuver (RAM) is derived from the fact that she is *unable* to keep out of the way of another vessel due to the nature of her work. Under both the International and Inland Rules of the Road (COLREGs Rule 3(g)), a RAM vessel is 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." This definition grants the RAM vessel high priority in the hierarchy of privilege (Rule 18), requiring nearly all other vessels (including fishing vessels, sailing vessels, and vessels towing) to keep clear of her. *** **Why the other options are incorrect:** **A) Vessel towing:** A vessel towing is generally considered "hampered" or "constrained" because of her tow, and she has less maneuverability than a standard power-driven vessel. However, she is *not* legally defined as "unable" to keep clear. A vessel towing is required to keep out of the way of vessels that are Not Under Command (NUC) and vessels Restricted in their Ability to Maneuver (RAM). **C) Vessel engaged in fishing:** A fishing vessel is hampered by her gear and is granted certain privileges (power-driven vessels must keep clear of her). However, she is still defined as *able* to keep out of the way of a Vessel Not Under Command (NUC) and a Vessel Restricted in her Ability to Maneuver (RAM). **D) Sailing vessel:** A sailing vessel is one of the most highly maneuverable vessels and is required to keep out of the way of NUC vessels, RAM vessels, and vessels engaged in fishing. While privileged relative to a power-driven vessel, she is fully capable of taking action to avoid collision in all other scenarios.
