Venetian Galleasses (Galeazze) were military ships, whose build developed from large merchant galleys named “grosse”, and their purpose was to combine galley speed with the sea-worthiness and artillery of a galleon. The ship was equipped with a forecastle, aft castle, and two decks, one of which was used for rowers who guaranteed mixed propulsion alongside its large Latin rigs set on a long yard mounted at an angle on each of the three large masts.
