A narrowboat is a type of canal boat, but not all canal boats are narrowboats. Canal boats are boats designed for use on canals, rivers, and other inland waterways. They are typically long and narrow, with a flat bottom and a shallow draft. Canal boats can be used for a variety of purposes, such as transportation of goods and people, leisure cruising, or even as permanent residence. Narrowboats are a specific type of canal boat that are designed to navigate the narrow canals of the UK. They are typically up to 7 feet (2.1 meters) wide and up to 70 feet (21 meters) long.

The term "canal boat" is a more general term that can include a variety of different boat types, including narrowboats, wide-beam boats, and Dutch barges, among others.
