Basically I'm tagging general characteristics of waterways. It seems the categories will be: *maintained for deep draft ocean vessels *maintained for shallow draft barges and pleasure boats *not maintained, possibly open to pleasure boats I don't see any such values in the Seamark Tag Values table. The closest is depth_max (shouldn't this be maxdepth, to match such tags as maxheight?), but there don't seem to be legal depth restrictions on most waterways here.
The seamark tags are aligned on the IHO-S57 Object & Attribute catalogue and are aimed at the generation of navigation charts, so are unlikely to provide for your needs.
I have not come across tags more detailed than "boat=yes" for general waterway data. Even that tag is ill-defined - nobody is sure whether it is an indication of permission or of navigability.
