As of September 2020, if you are a national of a Schengen / EEA state, you can generally travel within the Schengen Zone, however there are increasing restrictions upon arrival, e.g. testing and self-isloation. It is on a country-by-country basis, so read carefully. Foreigners not belonging to the Schengen Zone / EEA are likely still prohibited entry and/or facing tight restrictions for entry. Read the fine details below before attempting a reservation.
If you are travelling for work, the regulations may be more relaxed.
Countries in the EU/Schengen are beginning to open their borders to external (non-EU/Schengen/EEA) countries on a country-by-country basis. As a foreign national of one of these external countries, it may be possible to take a ferry on the Baltic Sea, but you should surely research ahead of time. Citizens and lawful residents of the EU shouldn't face difficulties in taking a ferry for recreational purposes at this time.
Also note that ferry operators in the Baltic Sea have implemented strict social distancing and cleaning rules in order to continue operating. As a result, many common areas such as cafes, restaurants, and saunas have been closed for the time being.
