— JUST OUT OF INTEREST
A showboat, or show boat, was a floating theatre that traveled along the waterways of the United States, especially along the Mississippi and Ohio rivers, to bring culture and entertainment to the inhabitants of river frontiers.
WIKIPEDIA
Showboats were a special type of riverboat designed to carry passengers rather than cargo, and they had to be pushed by a small (and misleadingly labeled) towboat, also known as a pusher, which was attached to it.
Showboats were rarely steam-powered because the steam engine had to be placed right in the auditorium for logistical reasons, therefore making it difficult to have a large theatre.
