What does "experimental" hull mean?

[Peksern]

Question is probably self explaining. I'm simply curious, what these hulls mean. Are they made by some ships that were never completed in history? Historical studies, that were never built? Or what is the difference and sense of the experimental battleships/dreadnoughts (or cruisers, if there are any ingame?)

I'd say experimental hulls have two meanings here as far as I can tell. Either they pertain to paper designs never built or they are arbitrary designations made by the developers to explain weird layouts for the aforementioned hulls.
