Barcos Rabello
Rabello boats, unique to the Douro, were used to bring wine barrels downriver to Porto. Today they are used as wine company advertising props.
"The curious Barcos Rabello used for this purpose are flat-bottomed barges with an enormous rudder; and it requires no little skill to pilot them safely past the innumerable reefs, shallows, and rapids of the Douro".--Baedeker 1913.
