A small passenger ship with considerable history in the Greek Seas, Zatouna was built as the small Zara by M. Martinolich of Lussinpiccolo in 1890. It should not be confused by an 1891 yacht by the same name that was built by Fleming & Ferguson of Paisley and eventually became the Greek passenger ship Electra and Electra Stavroudi.. Marco U. Martinolich & Co. of Mali Lošinj (Lussinpiccolo) in the island of Lussino (Αψωρος in Greek) in the Northern Adriatic was a smaller but well known Austro-Croatian shipyard. In 1885 they began building iron ships. See http://zeljko-heimer-fame.from.hr/descr/hr-ship1.html
Zara had 172 tons, a length of 34.7 m and a width of 5.5 m. She was used in the Dalmatian trade, mostly connecting smaller Dalmatian islands with Zara (Zadar) and Spalato (Split).
In 1904 or 1905 she was sold and became Creta but it is not known if she was a Greek ship then.
She was sold to the Greek Atmoploia Damoulaki in 1909 and became Zatouna. Here is a Damoulakis schedule from 1916

After this, things get really confusing. Tzamtzis who is usually a good source of early information claims that the ship was still Zatouna of Atmoploia P Damoulaki in 1921 and she had 204 tons by that time. He also notes she passed to Atmoploia K Giafis & Cia in June 1921. He makes no mention of Mihail or subsequent incarnations!
*** It must also be noted that Tzamtzis notes the existence of one more Zatouna (in the 1890s) belonging to Anatoliki Atmoploia of Pantaleon.
My sources are significantly different.
Zatouna was definitely there in 1916 as you can see from numerous ads of that period. Here is one from November 14, 1916 when the ship did the usual coastal route in the Corinthian and Amvrakikos gulfs.

And then we find her on August 1, 1920 as Mihail going up the Evoikos, Pagasitikos and all the way north to Thessaloniki. In a 200 ton-ship, obviously the passengers were not sleeping in quarters, just sitting and catching a cold covered with blankets!

The naming of Mihail agrees with all the information from Lloyd Register.
Around 1925 comes the transfer to Atmoploia D. Seretis of Piraeus (Tzamtzis mentions her in 1929) and the renaming as Evanghelistria with a reduction to 172 tons. Finally, in 1938 she was bought by K. Filinis and rename Evoia. She was listed in Lloyd all the way to 1945
