This category includes subcategories for propeller-driven, side-wheel driven, and sternwheel-driven steamboats. It's not necessary to use the subcategories, but they may help find related types of vessels more quickly. The images in the gallery below show examples of some of these vessel types. Steam ferries and steam tugs may be driven by propeller, side or stern wheels, so these categories can overlap.
