A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels.

Steamboat engines were routinely pushed well beyond their design limits, tended by engineers who often lacked a full understanding of the engine's operating principles. With a complete absence of regulatory oversight, most steamboats were not adequately maintained or inspected, leading to more frequent catastrophic failures.
