That’s Tight. Corinth Canal

The Corinth Canal is a canal that connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It saves the 700-kilometre (430 mi) journey around the Peloponnese, it is too narrow for modern ocean freighters as it can only accommodate ships of a width of up to 16.5 metres (54 ft) and a depth of 7.3 metres (24 ft). Ships can only pass through the canal one at a time on a one-way system. Larger ships have to be towed by tugs. The canal is nowadays mostly used by tourist ships; 11,000 ships per year travel through the waterway.
