Cruising Baltic Sea
The Baltic holds the greatest archipelago cruising on earth: tens of thousands of granite skerries threading the Swedish and Finnish coasts, where you nose into a rock cleft, run a line ashore, and have an islet to yourself. It is brackish with almost no tide, but the rocks are unforgiving and the season is short and bright. This region covers Sweden, Finland, Denmark, Germany, Poland and the Baltic states — from the Danish belts to the Gulf of Finland.

Questions
Are the skerries and rocks charted?
Yes — the rock-strewn archipelagos are exactly what this region is built for, with depth-aware routing tuned to the narrow leads and community-verified rocks and navaids.
Is there tide to worry about?
Almost none — the Baltic is nearly tideless and brackish. Water level shifts with wind and pressure, which the bundled data reflects.
Does it cover both Sweden and Finland?
Yes — the Swedish and Finnish archipelagos, Denmark, Germany, Poland and the Baltic states, all in one region.
