Classification of European Inland Waterways
The Classification of European Inland Waterways is a set of standards for interoperability of large navigable waterways forming part of the Trans-European Inland Waterway network within Continental Europe and Russia. It was created by the European Conference of Ministers of Transport (ECMT; French: Conférence européenne des ministres des Transports, CEMT) in 1992.
This inland waterway classes agreed on by the commission are referred to as CEMT Class I–VII. These classes refer to the dimensions of ships that should be able to use a canal. For their height, the classification determines the minimum air draft of bridges on the waterway. The dimensions of structures like bridges, locks and boat lifts relate very directly to the size of vessels. However, for the canals themselves, this relation depends on local circumstances.
