Punt

A punt is a flat-bottomed boat with a square-cut bow, planned for use in small rivers or other shallow water. Punting refers to boating in a punt; the punter normally propels the punt by pushing beside the river bed with a pole.
Punts were initially built as cargo boats or platforms for fowling and angling but in modern times their use is almost wholly confined to pleasure trips on the rivers in the university towns of Oxford and Cambridge in England and races at a few summer regattas on the Thames.
A customary river punt differs from many other types of wooden boat in that it has no keel, stem or sternpost. In its place it is built rather like a ladder with the main structure being two side panels connected by a series of 4 in (10 cm) cross planks, known as "treads", spaced about 1 foot (30 cm) apart.
The first punts are traditionally linked with the River Thames in England and were built as small cargo boats or platforms for fishermen. Pleasure punts — particularly built for recreation — became popular on the Thames between 1840 and 1860. Some other boats have a similar shape to a traditional punt — for example the Optimist training dinghy or the air boats used in the Everglades — but they are normally built with a box construction instead of the open ladder-like design of a traditional Thames pleasure punt.

Narrow boat

A narrow boat or narrow boat is a boat of a characteristic design, made to fit the narrow canals in the British Isles.
In the context of British Inland Waterways, "narrow boat" refers to the original working boats built in the 18th, 19th, and early 20th centuries for transport goods on the narrow canals (where locks and bridge holes would have a maximum width of 7 feet) built in the English midlands during the industrial revolution. The term is extensive to modern "narrow boats" used as homes and for recreation, whose design is an explanation of the old boats for modern purposes and modern materials.
