My wife and I have recently returned from our Russia river cruise via Viking.
We actually sailed on a combination of canals, rivers, and lakes from Moscow to St Petersburg on the Viking Helgi.
The Helgi is larger than the “longboats” we’ve sailed in previously on the Danube. Though longer, they have two decks, while the Russian river boats have four. The Russian boats are certified to sail in the ocean—but not too far from land. This was good, because some of the lakes we crossed were enormous. There are quite a few of these boats, all based on the same design. The Helgi was built in 1984. Viking acquired five of the boats in 2008 and completely stripped the interiors and rebuilt them to reflect the standards that Viking passengers are familiar with. The difference between the Viking ships and the other Russian boats is very apparent. The boats frequently dock side by side—you often have to walk through one or even two boats to get to yours, especially in the larger cities. There’s a dramatic difference when first walking through a Russian boat then onto ours. The Russian boats are quite drab.
Very comfortable, but sound from neighboring cabins can be heard
