Unfortunately no outside deck on this vessel guys so the shots I got on it were fairly poor, however this is a very interesting route if you ever get a chance to do it.
This is the speedy ferry, "buque rápido", to Montevideo, with no outside decks. I almost always travel with the slow ones, to Colonia del Sacramento, and then to Montevideo with the bus. If the weather is good, I pass all the time in the outside deck. When you come back, perhaps you could visit Colonia too, it is a magic place.
I took Buquebus to Colonia and it didn't have an outside deck either, which was very disappointing because it was a nice warm day in October. I don't know if the other two ferry companies have outside decks on their ships, but they go only to Colonia. A lot of people take the ferry to Colonia and the bus to Montevideo because it's less expensive. I just took a day trip to Colonia, returning to Buenos Aires in the evening, and it was very nice.
It’s a very long way from where I live, I was there to visit BA and Montevideo both of which I enjoyed very much even though the video for my channel didn’t work out 😀
