A Sailing Directions
B U.S. Army Corps of Engineers Navigation Regulations (Blue Book)
C U.S. Coast Pilot
D Tide Tables
AI Explanation

The correct answer is B) U.S. Army Corps of Engineers Navigation Regulations (Blue Book). Vessels regularly navigating the Ohio and Mississippi rivers above Cairo, Illinois, and their tributaries are required to have a copy of the U.S. Army Corps of Engineers Navigation Regulations, also known as the "Blue Book," on board at all times. This regulation is specified by the U.S. Army Corps of Engineers, which is responsible for maintaining and regulating navigation on these waterways. The other options are incorrect because: A) Sailing Directions are not specifically required for these inland waterways, C) U.S. Coast Pilot is a more general publication, and D) Tide Tables are not relevant for these inland rivers.
