Immediately after the liberation of Thessaloniki, smaller coastal shipping companies were established to serve areas around the city and the prefecture (nomos). I am summarizing below a few of them, all from ads in Makedonia, Thessaloniki's prominent newspaper.
It must be noted (as it will be presented in other threads) that numerous nationally-known passenger ships were serving Thessaloniki and connecting her with Piraeus, Volos, Mytilene, Chios, Crete, Patras and even Corfu. They included Alkmini, Chios, Neilos, Popi and many others. Just to see the diversity of travel from Northern Greece in those days, please look at teh schedule of June 13, 1925 from Thessaloniki.
