Viking is unusual among major cruise lines in that it operates both ocean ships and river ships. Despite this, it has one of the easiest-to-understand fleets.
The vast majority of Viking's river ships — at last count, there were more than 80 — feature the same design. If you've seen one of them, you've seen them all.
Ditto for the line's ocean ships. Twelve of Viking's 14 ocean ships are nearly identical. The two exceptions are two ocean vessels specifically designed for expedition cruising — a type of cruising that involves traveling to remote, hard-to-reach places on hardy vessels that carry their own landing craft.
