Greece. Corinth Canal. Tourists sailing on cruise ship through the isthmus of Corinth, using the Corinth Canal. The Corinth Canal is a canal that connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnesian peninsula from the Greek mainland, thus effectively making the former an island. The builders dug the canal through the Isthmus at sea level; no locks are employed. It is 6.4 kilometers in length and only 21.4 meters wide at its base, making it impassable for most modern ships. The bow is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. 1.06.92 © 1992 Didier Ruef
