Hello, I decide to report it on the forum, because it is still impossible to apply the mapping rules, I looked through the editions in other countries and they mark the coastline as breakwaters along with groynes and embankments. How should it be consistent with art? The breakwaters are not turned on at all, is the breakwater alone without the star blocks turned on, or is the entire breakwater and the embankment turned on? How to deal with the coastline???

Apparently it’s good according to the rules: Report: Polish internal sea waters (10188446) | OpenStreetMap3
