Which vessel is NOT considered "restricted in her ability to maneuver" according to the Rules?

A sailing vessel is not considered "restricted in her ability to maneuver" under the USCG Rules of the Road. The term "restricted in her ability to maneuver" refers to vessels that cannot navigate normally due to specific operational constraints, such as those engaged in dredging, underwater operations, or towing another vessel.

A sailing vessel, while it may sometimes have limitations due to its reliance on wind and can be affected by sailing conditions, is generally able to maneuver and respond to navigational challenges without being classified as restricted in its ability. This classification is important because vessels that are restricted have particular rights concerning their navigation and the responsibilities for other vessels when it comes to avoiding collisions.

In contrast, a power-driven vessel could potentially be restricted depending on its operational status, vessels engaged in dredging are typically limited in their maneuverability due to their equipment, and a vessel towing another vessel can also face limitations due to the need to maintain control over the towed entity.
