CEMT is a classification for European inland waterways and extends waterway=* (axis of river, canal, fairway). CEMT=* is used on the European waterways that make up its water-based transportation network.
CEMT=* should only be used in correspondence with the official CEMT classification of the waterway. For waterways that lack a CEMT classification, see the other water-based transportation tags in the access tree.

The unofficial classificiation CEMT=0 is often used when source data (such as government provided data on waterways) marks this as a waterway suitable for general recreational use. CEMT=0 implies motorboat=yes and canoe=yes, but also tends to strongly imply ship=no.
The presence of CEMT=* with value of I or higher, implies that an inland waterway is (within the size and draught constraints shown in the table above) for the purposes of water transport.

CEMT=* is not the only tag that can indicate navigability on waterways. Outside of Europe, ship=* may be used instead for shipping links. For waterways that lack a CEMT=* tag, boat=* and its descendants can be used to indicate navigability by smaller vessels.
