I'm from Aveiro, I lived in Porto for a few years, but as soon as I could I returned to Aveiro! I've always sailed on the Ria (estuary), my family has always had a boat, not for work, but for leisure! That's one of the reasons why there's no one doing this type of expedition, as it requires a deep understanding of the small channels among the old salt marshes!
In 2009 I started rebuilding the old ferry boat, built in 1945, naming it "Praia da Costa Nova," with the idea of developing tourist expeditions through the Ria and the Aveiro region for groups and individuals.
