A narrowboat, also known as a narrow boat, is a type of boat that is long and thin, designed to navigate narrow canals and waterways. However, there are numerous other synonyms used to describe this type of vessel. Some of the most common include narrowboat, longboat, and canal boat. Other terms that are often used include barge, a type of flat-bottomed boat typically used for cargo transport, and skiff, a smaller type of boat that is usually used for leisure activities like fishing or rowing.
