Can big ships and modern cargo vessels use the Corinth Canal?
Posted on Mar 01, 2026 / Travel
Not really — most large modern ships can’t fit through the Corinth Canal because it’s too narrow and shallow for heavy commercial traffic. The waterway’s width at sea level is only about 24.6 m and it’s around 8 meters deep, which is great for small boats and pleasure craft but too tight for full-size container ships and tankers. Because of this size limit, the canal never became a major commercial shipping route like the Suez or Panama Canals, and its yearly tonnage is much lower than originally expected. Even cruise ships generally can’t pass through unless they’re carefully piloted or assisted due to the tight fit; one notable exception was the cruise ship MS Braemar in 2019, which managed to squeeze through with minimal clearance. Most trade traffic still sails around the Peloponnese instead, while the canal itself serves mostly tourism, small cargo, and local transit. This unique mix makes the Corinth Canal more of a scenic historic route than a major global freight corridor.
