I would rate this book as a "must-have" for anyone cruising the Tennessee River. We've also used it to help transit the TennTom Waterway from the Tennessee River down to Mobile, and it was quite helpful there as well, although somewhat dated. When the TennTom portion of the book was written the waterway was quite new, and with the passage of 10-15 years some of the recommended anchorages have shoaled and become unusable for boats of anything but very shallow draft. Still, this guide helped us find more than one excellent anchorage that we likely would have missed otherwise.
