Which type of vessel is considered "Restricted in Ability to Maneuver"?

A vessel is considered "Restricted in Ability to Maneuver" if it is unable to follow the normal navigational rules due to the nature of its operation. A mine sweeping or clearing vessel falls into this category because it engages in activities that obstruct its ability to maneuver quickly or change direction, primarily due to the need to safely detect and remove underwater mines. This task often requires the vessel to maintain a steady course and speed to effectively conduct its operations, which can limit its navigational flexibility.

In contrast, vessels like cargo ships, fishing vessels, and passenger ferries may have operational constraints but do not inherently possess the same limitations in maneuverability as a mine sweeping vessel does when it is actively clearing mines. Hence, the designation "Restricted in Ability to Maneuver" specifically applies to those vessels engaged in specialized operations that require them to maintain certain courses or actions that limit their ability to respond to other navigational challenges.
