Openseamap
I recently found openseamap.org
I really like it as it’s pretty detailed in Europe, and I regularly go to lakes and rivers which are either bad in C-Map or I have to buy another area just for that.
I have found they have some downloads, but again they only cover part of Europe.
Is there any way I can get their online map or get that data over to Exp?

I haven't tried them, but they say they have BSB (.kap) charts.

Re: Openseamap
If anyone has tried this and made it work with Expedition, let us know - I for one would be very interested. The charts seem reasonably good and cover the west of Ireland which is what I am looking for.

Also, many of the European Inland waterways are available as ENCs, see the Exp charting web page.

Hmm for some reason I’m not getting notifications about answers. Good thing I come here a lot! 
Yes I found the bsb files. For some reason they have not packaged all of Europe in them. Naturally the missing part is what I need.
Does MBTiles work?
Also, they say they have world coverage in B&G format in .at5 files. Can we use that?
On this site they list more formats:

Re: Openseamap
Exp doesn't support MBTiles. They are just BSB charts in an SQLite database. NOAA is ceasing RNC production, so they won't be added.

Re: Openseamap
Are at5 files RNC?
