Vessel restricted in her ability to manoeuvre?

A vessel restricted in her ability to maneuver refers to a ship that cannot change its course or speed as a result of the nature of its work or the conditions it is operating under. This may include vessels engaged in activities such as towing, dredging, or laying pipelines. Such vessels are typically marked with specific signaling equipment and are given precedence in navigation to prevent collisions. Other vessels must exercise caution and provide assistance if necessary when navigating near these restricted vessels.
