The rabelo boat is a traditional Portuguese wooden cargo boat that was used for centuries to transport people and goods along the Douro River. It is flat-bottomed, with a shallow draught, which was necessary to navigate the often shallow fast-flowing waters of the upper Douro prior to the construction of dams and locks from 1968 onwards.

Native to the Douro region, it does not exist in any other place in the world. Its history is closely linked to the production and trade of port wine. Before the arrival of the Linha do Douro railway, the rabelo was the fastest and the most efficient means of transport between the Douro Valley, where port wine is produced, and the city of Porto, where it was traded and exported worldwide.
