Rules for Vessels: Understanding Vessel Restricted in Her Ability to Maneuver

Which vessel is a "vessel restricted in her ability to maneuver" under the Rules?

A. A vessel engaged in fishing

B. A vessel not under command

C. A vessel mineclearing

D. A vessel at anchor

Final answer:

A vessel not under command is considered a "vessel restricted in her ability to maneuver" under the Rules.

The vessel that is considered a "vessel restricted in her ability to maneuver" under the Rules is a vessel not under command. This means that the vessel is unable to maneuver due to exceptional circumstances, such as being disabled or having a machinery failure. When a vessel is not under command, it is required to display the appropriate day shapes and lights to inform other vessels of its restricted ability to maneuver.

For example, if a ship experiences a steering failure and cannot be directed or controlled, it would be considered not under command. It is important for other vessels to be aware of this so they can take appropriate action to avoid a collision.
