Water churns under the circular red paddles of a massive, wooden wheel, and, as dusk falls, the green shoreline slowly waves goodbye. Strings of bright holiday lights shimmer on two wooden decks, reflecting in the water’s darkening surface. The moon looks on.

On both evening and day cruises, Tennessee Riverboat Company’s captains steer the Star of Knoxville and its passengers past the river’s shoreline foliage. Buffet-style meals and an ever-changing lineup of live entertainment captivate guests without forcing them to bunk with prop comedians. Seasoned captains pilot their ships through calm waters, pointing out spots of interest while passengers lounge in air-conditioned or heated interiors. Participants may also take to the dance floor as decks fill with gospel or country tunes on themed music cruises, where performers encourage participation to help expose stowaway Dolly Partons.
