Final answer:
The true statement about the Inland Navigation Rules is they list requirements for Traffic Separation Schemes. These rules are established by the US Coast Guard to prevent collisions. The rules do not define 'moderate speed' nor require radiotelephone communication for passing.
Step-by-step explanation:
The statement that is TRUE concerning the Inland Navigation Rules is 'C. They list requirements for Traffic Separation Schemes'. The Inland Navigation Rules are a set of regulations established by the US Coast Guard that provide guidance for the operation of vessels in inland waters. These rules, which are intended to prevent collisions between vessels, outline various requirements for navigation, such as conduct of vessels, lights and shapes, sound and light signals and exemptions, among others. One key aspect of these rules is the listing of requirements for Traffic Separation Schemes (TSS), which are measures established to separate shipping lanes for vessels traveling in opposite directions or crossing a given route. Statements A and B are incorrect; the rules do not explicitly define what constitutes 'moderate speed' nor do they require communication by radiotelephone for passing agreements.
