I am sorry the blog is in Portuguese, but the images are multi-language.
These boats, the Rabelo sailboat, were and are the traditional boats of Porto, North of Portugal, and they were used to sail up and down the river to carry the PORT WINE skegs from the producers in the Douro river all the way to the city of Porto or Oporto in English.
Look at the images....amazing...really...no gimmics, no hardcore tools, no glass no st60 nothing...man and ingenuity
Have fun. See it here
Ahhhhhhhhhh Portugal do meu coração, e das gentes valentes e fortes......
