What does the term "restricted ability to maneuver" indicate in vessel hierarchy?

The term "restricted ability to maneuver" specifically refers to a situation in which a vessel faces limitations that impede its ability to change course or speed effectively. This can occur due to various operational constraints or environmental factors, such as being constrained by shallow waters, other vessels, or navigation hazards.

When a vessel has a "restricted ability to maneuver," it is important for other vessels to understand that this ship may not be able to execute standard maneuvers to avoid collisions or navigate safely. This status is crucial for ensuring safety at sea, particularly in congested waterways or during complex operations.

The other options relate to different statuses or activities of vessels. While the vessel being "not under command" means it cannot respond to the steering commands, that is a distinct maneuverability issue. A vessel "sailing" or "fishing" refers to specific operational activities, rather than its ability to maneuver. The focus on maneuverability in the context of this term underlines the nuances involved in maritime navigation and communication.
