Which scenario is NOT to be regarded as restricted in her ability to maneuver?

• A. A vessel towing another with a rope
• B. A vessel sailing without engine
• C. A vessel pushing and a vessel being pushed when connected in a composite unit
• D. A vessel idle at anchor

Answer: (C)

The concept tested is when a vessel is considered restricted in her ability to maneuver (RAM). RAM applies to vessels whose current work or condition naturally limits how quickly or easily they can change course or speed, so other vessels must take early action to avoid them. In a scenario where two vessels are pushed and pulling a third as a single connected unit, they are treated as one unit for maneuvering purposes. The combined movement is planned and controlled as one motion, so there isn’t an inherent restriction on each vessel’s ability to maneuver separate from the unit. That’s why this composite-pushing arrangement isn’t regarded as RAM. By contrast, towing a vessel with a rope imposes limits because the towed vessel’s behavior directly affects the tug and the line, requiring the towing vessel to manage tension and steering in a constrained way. A vessel sailing without engine depends on wind and current, which can limit her ability to steer or speed up on demand. An idle vessel at anchor cannot maneuver at all while anchored. All of these involve restrictions on immediate maneuverability, unlike the connected-pushing unit.
