Previously we had a question about ferries between Ukraine and the Republic of Georgia. The answer was that the company UkrFerry has such a route but I'm unsure of the details and the site seems to be mostly in Russian.
What I'm wondering is if the ferry goes via Russia and if so is it possible to travel say from Kerch to Poti without the need to obtain a Russian visa? (Impossible for me anyway since I would have to apply in Australia and I'm already in Europe).
