I can't find any information on the shipwreck of the Dimitrios, or even on the ship itself. If you know anything about it, let me know and I'll update this post.
The Dimitrios is beached near the city of Gytheio.
Gytheio : (Greek, Modern: G??e??, Ancient/Katharevousa: G??e???) (Meaning: Land of the Gods), also Gythio, Githeio, Githio or Yithion is a town in the prefecture of Laconia in Greece, long known as the seaport of Sparta some 40 km away. Gytheio used to be an important port for many centuries until it was destroyed by an earthquake.
