The works were divided into a first underwater phase and a subsequent dry phase, made possible thanks to the delimitation of the entire area and the wrecks have been discovered in an exceptional state of conservation, perfectly protected by the mud of the lagoon. The galea is the most important type of "longship" of the Medieval Age equipped with both rowing and sailing propulsion and it represents one of the most important wrecks ever discovered, being the only one that can be certainly identified as a Medieval galley. The place of discovery and the archive documents confirm that it is a Venetian galley; one of those with which the Serenissima organized traffic to Greece, Black Sea, Eastern Mediterranean, North Africa, the coasts of Tyrrhenian Italy, Western Mediterranean, Flanders. The rascona was a large flat-bottomed cargo boat of the fluvial-lagoon type that navigate from Venice along the Po river to ports of the river cities, till to reach Pavia. A peculiar characteristic of this riverine ship was the two large lateral rudders, such as ancient ships. The type of rascona has experienced a very long survival over time, remaining almost identical from the Middle Ages until the early twentieth century. 
The two shipwrecks have been the subject of an extensive documentation campaign with photogrammetric survey and 3D reconstruction of the wooden elements.
