This is historical. At the beginning of nautical navigation mapping, it 
was buoys, beacons, lights, etc that were being mapped. As is usual with 
OSM mapping, feature creep set in to include all objects listed in the 
IHO catalogue. In retrospect, a broader term than "seamark" would have 
been better, but like many other ill-fitting tag keys, we are stuck with it.
