keelboat
Noun: A keelboat is a type of river boat characterized by a shallow draught (the depth of water a boat needs to float) and a keel (a central structural base or spine running along the bottom). It is designed to carry freight (cargo or goods) and is propelled by human power through rowing or punting (pushing with a pole), or sometimes by being towed from the riverbank. Unlike many boats, a traditional keelboat does not use sails for propulsion.
The word "keelboat" is used specifically to refer to this historical type of cargo vessel. It describes the boat's physical structure (shallow draught, keel) and its primary function (freight transport) and method of movement.
- In the 19th century, the keelboat was a vital link for transporting goods on inland waterways before the rise of steamboats.
- The museum displayed a replica of a freight keelboat, complete with oars and a long tow rope.
- Moving a loaded keelboat upstream required great effort, often involving a crew rowing or men towing it from the shore.
- The term is often used in historical contexts discussing early American river trade and exploration.
- "Keelboatman": (a related term) refers to a person who operated or worked on a keelboat.
- Keel (noun): The central structural base of a ship or boat, running lengthwise along the bottom.
- Flatboat (noun): Another type of shallow-draft freight boat, often without a keel, used on rivers.

- Cargo boat (for river use)
- Barge (a broader term; some barges are keelboats, but not all barges have a keel or are propelled in the same way)
- Sailboat (a boat primarily propelled by sails)
- Steamboat (a boat propelled by a steam engine)
