Which of the following is NOT considered restricted in her ability to maneuver?

• A. Vessel Dredging
• B. Sailing Vessel
• C. Vessel Servicing A Navigation Marker
• D. Vessel Mineclearing

Answer: (B)

The situation tests understanding of what it means for a vessel to be restricted in her ability to maneuver (RAM). A RAM vessel is one whose operations prevent easy or safe deviation from a planned course, typically because the work must be performed in a fixed area or with limited steering and speed. Dredging, servicing a navigation marker, and mine clearance all involve activities that keep the vessel in a constrained position or require careful, slow, or precise maneuvering, so those vessels are RAM and must keep clear of other traffic and take early action to avoid collisions.

A sailing vessel, however, is not restricted by the nature of her work in the same way. She can adjust course and speed as needed to avoid other vessels, even though wind and sail handling affect her maneuverability. Therefore, she is not considered restricted in her ability to maneuver, which is why this option is the correct answer. In practice, RAM vessels require other vessels to give way and take precautions well in advance.
