A common feature on UK rivers is a 'barrel line' approaching a weir, to prevent boats passing over the weir by accident and damaging themselves: see here. That particular barrel line has been mapped by dzizek23 as a barrier=chain, with a description to explain the feature. That seems quite good, and it renders nicely (*ducks for cover). As a water user I would quite like barrier=floating-chain or barrier=barrel-line as that would be specific for the water feature rather than repurposing a land feature for it. It would be useful for canoeists and others planning what barriers they may be able to pass over/under. But maybe that's just adding complication? Does anyone know if these are mapped elsewhere? Are there views on whether they should be a barrier=chain or something else? Or should this question be asked elsewhere? Thank you. PS substitute _ for - (underscore confuses the markdown) |

I believe the correct name is barrier=boom for a linked set of buoys around prohibited areas, though wiki does not seem to document this as expected. Maybe barrier=buoy is another choice 2
There's OpenSeaMap documentation for

Thanks both. I've updated the wiki at Key:barrier, and will hopefully produce the page Tag:barrier=boom at some point soon. I would suggest barrier=buoy should be avoided as a buoy is generally a point object.

Just for info, I've now found this related question from 2014: https://help.openstreetmap.org/questions/37418/tag-line-of-floating-buoys-near-weir-or-dam |
I think the underscore will not confuse the markdown if you wrap your tags in backticks `.
Hi eteb3, see this one I made as newbie, https://www.openstreetmap.org/#map=19/52.23591/5.05936
In the Nordic countries, it also is common to have barriers that look similar to those that @eteb3 refers to, but they are intended to stop floating pieces of ice well ahead of a hydropower station. They consist of a set of buoys linked with heavy wires.
