R/B River Explorer, which carries 198 passengers on two interlinked 295-ft. long barges, traverses the Mississippi River and Intracoastal Waterway on fout-to-ten day excursions. With interiors designed by Bauer Interiors, convertability was the prime directive throughout much of the vessel to allow a multitude of uses within a single space. In the lobby area, each etched glass partition between the two-man booths is an engraving of a major bridge spanning the Mississippi River from Ohio to New Orleans. The interior of the Sprague Theater is outfitted to resemble the interior of the vessel by the same name, the largest cargo-carrying towboat on the Mississippi River in the 19th Century.
