The tags with keys that are prefixed "seamark:" are explicitly direct 
equivalents to objects and attributes registered in the IHO S-100 
catalogues and have meanings defined by IHO. This enables direct 
conversion between marine ENC files and OSM tags (and vice versa). The 
imported data from WSV is encapsulated in IHO ENC files.

It is not a problem to have dual tagging of objects, indeed it is 
necessary to differentiate the vernacular/OSM meaning of terms from the 
marine navigation meanings of the same vocabulary.
