BOTH INTERNATIONAL & INLAND What is a "vessel restricted in her ability to maneuver"?

Correct Answer: Option A — A vessel laying revetment mats to provide bank protection along a channel

Rule 3(g)(ii) includes vessels engaged in dredging, surveying, or underwater operations within the definition of "restricted in her ability to maneuver." Laying revetment mats for bank protection is an underwater construction operation that physically limits the vessel's maneuverability under the Rules.
