It appears many of the big Russian rivers have passenger ships going along the river, in areas where roads and railways do not reach. What I have found so far:
- On the Yenisey river via PassazhirRechTrans, such as from Красноярск to Дудинка
- On the Pechora river, with RTK Komi: connectinng Усть-Цильма (Ust-Tsilma) with Ермица, Чаркабож with Щельяюр, Печора (Pechora) – Аранец (Aranets) – Усть-Щугер (Ust-Shchuger) (location of the European cold record at -58.1°C) – Вуктыл (Vuktyl), and Печора (Pechora) with Озерный.
- On the Lena River by Lenaturflot, such as from Yakutsk to Tiksi, between Усть — Кут (Ust-Kut) and Пеледуй (Peleduy).
- On the Ob River by Severflot, such as between Омск (Omsk) to Салехард (Salekhard), and also routes on the Irtysh, Konda, Kazim, Severnaya Sosva, Lyapin, Nadym, and Vakh rivers.
It seems such boats could be a suitable way to connect from the Trans-Siberian railway to (even) more remote locations (such as the vicinity of Lake Vivi), where roads and railways do not reach. However, I find it difficult to find information about such boats, routes, schedules, etc.. Where can I find an overview, preferably a map, of long-distance boats in Russia? By long-distance boats I mean boats that run along the river for at least some dozens of kilometres, but preferably for several days, as opposed to ferries that simply cross the river from shore to shore.
Note that I'm looking for regular passenger ships, not special tourist cruises. Specifically, I'm looking for areas where travel by river is the only way of transportation, such as in the examples I've shown; there are no roads or railways in these areas.
I don't think this map from Wikimedia Commons shows actual passenger ship routes, just old used routes:
So, a map like this but with actually trafficated routes would be nice to see!
