Actually, the Stockholm Archipelago does. We have clear directions, starting from the entrances to the Archipelago and showing the route (fairways) into the harbors.
Here is the entrance to the Stockholm Archipelago at Söderarm. On the right hand side you can see how the route gets a direction with the red arrow and the two dots.

We can see one green lateral marker just north of the Rommargrund lighthouse, and one red marker to the WSW, marker "Fl R 3s"
Zooming out a little, we can see how the routes continue. In this case one route terminates at the port of Kapellskär, while another continues in SW direction towards Stockholm.

So the lateral markers are definitely in the Archipelago. I have sailed and motored the Stockholm, Åland and Turku ones, and have personal experience, as well as the charts.
Having said that, the image of Viking Sally that Vixen previously posted is definitely not at sea but inside the Archipelago. Most probably close to a port. It could be Mariehamn, or it could be Nådendal (next to Turku) - I can't really geolocate it. I'm almost be 100% sure it's not the Frihamnen in Stockholm, the background does not match at all, and it's an area I'm familiar with and have navigated in.
Given how the ship is moving, I'd say that the photographer is probably standing on land in the port.
Unfortunately I can't share any more details from the chart I just brought out, since it got invaded by a monster...
