Hello Roberto,
we went once uo to Porto Alegre during my time onbord. I think early 1970. What cargo we had I don´t remember but what I ´ll never forget was the trouble in the engine room with the sea intakes., the sea strainers. Due to the draft of the vessel and the low water on the Lagoa dos Patos we were more sliding through the seabed them floating. All engine crew, I was cadet, was permanentely over several hours cleaning the strainers full of mud, shells and other water spezies..... What a job. The engine room at the lower floor looked horrible with the mud and dirt everywhere. But we managed to get to Porto Alegre without stopping the engine and overheating. Years later I went up a couple of times with the Cosmo... ships of Aliança , but we never had any draft problems.
WEll, thats the story of the trip to POrto Alegre
BR Jürgen

Hello Jürgen,
It's a private postcard without any annotation in the back but the flag indicates that she is at Germany.
