Hi,
the groyne markers are not beacons and should also not be rendered like beacons. They are small stone plates showing the ref and the length of the groynes like this one (https://commons.wikimedia.org/wiki/File:Buhnenstein.jpg). I didn't find anywhere else where these are mapped, but I think using a new tag like seamark:groyne_mark similar to seamark:distance_mark makes more sense than reusing beacon_special_purpose. -

Within the S57 object catalogue there is no such object as a "groyne_marker". The type "beacon_special_purpose" is a carch-all for any kind of marker. This tagging is the only way to make these objects visible in nautical charts. If this is not important to you, an alternative would be to replace all the seamark tags with "man_made=groyne_marker" or similar.

I have no idea about whether these marks have any importance for nautical charts. I live near the river and just found out what these stone markers actually mean a few days ago. As I didn't find any tagging for these things, I thought it is best to adapt the seamark:distance_mark for this purpose. I didn't know that the seamark tagging scheme should only be used for elements defined in the S57 object catalogue. As these are clearly no beacons, I think it's best to use some tags like man_made=groyne_marker which do not interfere with the seamark scheme.
