Which term is not defined in the Inland Navigation Rules?

Towing light
Vessel constrained by her draft
In sight
Restricted visibility

The correct answer is: Vessel constrained by her draft

The term "vessel constrained by her draft" is not specifically defined in the Inland Navigation Rules. This term refers to a situation where a vessel's ability to navigate is hindered due to its deep draft when in shallow waters, but it does not receive a direct definition in the Rules. The other terms mentioned do have specific definitions within the context of the Inland Navigation Rules. For instance, "towing light" is a signal used to indicate that a vessel is towing another vessel. "In sight" refers to one vessel being visible to another, which can be critical for understanding right-of-way situations. "Restricted visibility" indicates conditions where visibility is limited, which influences navigational decisions. Understanding these definitions is essential for applying the rules effectively during navigation.
