I still find it strange to prefix everything with "seamark", e.g. landmark or harbour, objects for which there is also standard tags in OSM (what do we gain in duplicating them in different namespaces?).
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.
