This post is an recent interview with Tom Ray, who had an incident on his 42 ft Cruisers Yacht, on May 17, 2015 during a cruise on the Tenn-Tom Waterway. While underway all the electronics at the helm suddenly went dead. The only way to continue navigation was his compass and a paper chartbook.
Duthie Learning now publishes five chartbooks covering all the rivers from Chicago to Cairo, IL and then to the Gulf of Mexico either via the Tenn-Tom Waterway or the Lower Mississippi. Details here.
