The port of Mazara del Vallo (Port Code:ITMDV) is the only canal port of Sicily. It consists of three different basins: an outer port, a dry dock for fishing boats (also known as "new port") and the canal port. The history of the canal port has very ancient roots; raising at the mouth of the Mazaro river, it has always represented an essential reference point for maritime traffics in the Mediterranean Sea. The seabed depth is extremely variable. In the outer port, it is about 6-7 metres deep; in the new port, it is about 5 metres while, in the canal port, is ranges from 2 to 3 metres.
The port of Mazara del Vallo plays different important roles. First of all, it's an industrial port equipped with many shipyards involved in the construction of large vessels, mechanical and technical repairs and assistance. Then, the port guarantees oil supply thanks to a large fuel depot. Cruise and commercial ships dock at Mokarta and Ruggero II docks. Passenger transport services are carried out at Ammiraglio Francese and Giovan Battista Quinci quays.
