We only saw this in Cyprus. Father Iraklis made the established church service that for years now took place in the small church of Agioi Anargyroi in Kavo Greko, on a boat.
The original church on a boat was built because there is no longer any access from the steps to the church for the boat owners who are anchored in the Gulf of Cabo Greco.
So they were forced to bring Father Iraklis on a boat where the boat owners gathered to follow the established holy communion.
