What kinds of vessels are included under the definition of "vessel restricted in her ability to maneuver"?

The definition of a "vessel restricted in her ability to maneuver" includes specific types of vessels that, due to their work, cannot easily keep out of the way of other vessels. This encompasses vessels engaged in activities such as dredging, underwater operations, laying or picking up navigational buoys, and certain other types of marine work that require them to be stationary or to move with restrictions.

Vessels like those involved in dredging often have equipment extending over the side that restricts their ability to change course or speed. Similarly, vessels performing underwater operations might have divers in the water or equipment deployed that compels them to maintain a specific course. This operational aspect makes it essential for such vessels to be given the right of way in navigation to prevent accidents.

Other options do not fully capture the range of vessels that fit this definition. Only focusing on commercial fishing vessels does not represent the breadth of vessels that are considered restricted in their ability to maneuver. Recreational boats can vary widely in design and purpose, and many do not engage in operations that limit their maneuverability. Finally, the restriction applies to a wider category of vessels beyond just motorized vessels with crew; it includes non-motorized vessels when they are engaged in similar operations that limit
