Is a ferry a steamboat?
Not necessarily. A steamboat is a boat that is powered by steam (by propellers or paddle-wheels), so if the ferry is steam-powered, then it is a steamboat. Most ferries today have diesel engines and are not steamboats. Even if you can visually see a paddle wheel on a boat, it most likely still a diesel boat due to diesel being a lot safer. A lot of recreational river cruise boats have a paddle wheel added for show while the boat is actually being powered by a diesel engine. Most steamboats today aren't your classic "Mississippi Paddle-Wheel Riverboat" and are steam powered via propellers.
