Hello,

This changeset attract my attention because seamark with vhf 20 accross the canal in Brussels usualy take place near lock or movable bridge and that's not the case here. 

So i made a survey this morning ; see pictures here : https://www.openstreetmap.org/note/3635087 and i don't find any seamark on the bridge or surroundings. So where do you : 

- See a seamark (or have a document mention it)
- Take the seamark:name ? Is it guessed ?
