Baltic Seasteading
Do you live in one of the 9 countries adjacent to the Baltic Sea? Check out the new Baltic Seasteading group. Their website states:
Probably the greatest challenge of living at sea is dealing with waves, and the Baltic Sea has some of the lowest waves in the world while still big enough to contain international waters. This makes it a great place for seasteaders to start out and experiment with new structures and a new way of living.
Baltic Seasteading is a group for people interested in working actively with seasteading in its current state.
