Which of the following vessels would be considered "restricted in their ability to maneuver"?

Answer: C — vessel constrained by her draft

A vessel constrained by her draft is considered "restricted in their ability to maneuver" because its ability to move or change direction is significantly limited due to the depth of the water in which it is operating. This restriction typically arises when a vessel has a deep keel or is overloaded, making it unable to navigate safely in shallower areas. This designation is important under the COLREGs, as it establishes the vessel’s status in relation to other vessels and informs other mariners that special care should be taken when navigating in proximity to such a vessel. In contrast, a vessel operating in a wide navigable channel is generally not restricted in its maneuverability; it has ample space to maneuver. A vessel engaged in fishing may also have some limitations but does not automatically fall into the category of being restricted unless it meets specific conditions regarding gear or fishing methods. Finally, a vessel at anchor, while unable to maneuver, is not classified under the same requirements for restricted maneuverability as it can safely remain in place without the need to respond to navigational situations that require movement.
