> There is no way out of the Baltic Sea without crossing the territorial sea of either Sweden or Denmark. Countries have full jurisdiction in those [...] I don't think it's as clear cut. Transit passage through straits is governed by special provisions in the UNCLOS; with a few exceptions, states can't just board vessels. What could further complicate matters here is if infrastructure of states A and B is damaged, but a vessel leaves the sea through a strait bordering states C and D. That's obviously only the theory, and it's unfortunately not like there is broad international consensus on matters of territoriality at sea at this point.
