Understanding Inland Navigation Rules

Which term is NOT defined in the Inland Navigation Rules?

A. Underway

B. Restricted visibility

C. Seaplane

D. Vessel constrained by her draft

Answer:

The term 'Seaplane' is not defined in the Inland Navigation Rules.

The Inland Navigation Rules are a set of regulations aimed at preventing collisions between vessels in U.S. inland waters. Terms like 'Underway', 'Restricted visibility', and 'Vessel constrained by her draft' are clearly defined within these rules. However, the term 'Seaplane' does not have a specific definition in these rules.

A seaplane is an aircraft designed to land on and take off from water. Although this type of aircraft is not explicitly defined in the Inland Navigation Rules, it is important for operators of seaplanes to be aware of and follow the rules and regulations governing water operations to ensure safe navigation.
