So what do you think of these two ships? Are they too close to being semi-dreadnoughts?

KWorld

They look perfectly fine to me, classic predreadnought battleships.  It's really the Lord Nelsons, Dantons, and the Satsumas, with their 10-12 gun heavy secondary battery that are semi-dreadnoughts.

I see absolutly no problem with the 8" secondary main ship for 1895 (im doing much the same thing after all), I might question the 10" guns for the period however.  Post startup I however would see no problem with it, especialy since OTL the british went to 9.2" in around 1902. 

However you may want to play around with belt heights just a bit as you have almost 2' of unarmored freeboard (course they are tumblehome hulls which presents all its own known problems)

It's only a waterline area belt, typical of most battleships of the era.

A Russian version of the Connecticut class battleship. I imagine if drawn it would be quite the unusual looking warship.

Sneak home and pray that you'll never know

I'm interested in comments on this design, it is intended to be an early version of the type of hybrid armored cruisers/battlecruisers Russia built in the 1900s. In other words it is better armed and armored than an armored cruiser but not as well armed and armored as a battleship.

IMO, this is a well balanced cruiser for 1897
Powerfull armament, exellent protection & correct speed.
In a few years, with the technics progress; turbines , Dreadnought types, BCs...

She "ll be a correct 10000t AC with just 4 main guns.

An other choice is to have an AC with 6, 8 or 10 semi heavy guns - 8" for example.
2T2x8" + 6x8" in casemates.
I made that choice for my Marcillia type;1898-7500t-10x194+8x100-21kts

The shells for the 6" guns seem awfully light at only 80 pounds.  Other than that, the only question I'd have is the narrow hull: is a 54' hull going to be wide enough to fit a pair of 10" guns in the late 1890s?

Other than those two questions, though, she seems rather similar to my own USS Georgia design (yours trades some speed for more armor and heavier secondaries), or to the historical USS Tennessee or the Russian Rurik II.

The historic Russian 6 inch guns of this era used 80 pound shells, so I went with that. I'm not so sure about the 10 inch guns being able to fit on a 54 foot hull myself though, and there are not very many ships that mounted the 10 inch as a main armament to use as a pointer.

WHat I can find for period Russian 6"/45s says they used 91.2-91-.4 pound shells (http://www.navweaps.com/Weapons/WNRussian_6-45_m1892.htm).

I think I accidentally used the wrong weapon as the baseline. Looks like the shell weights are closer to those for a French 5.5 inch gun. I'll just go ahead and clean up the ships with the 6 inch later on, although it is almost all of my ships at least I do not have that many ship classes.

On another subject, I have a design for the torpedo boat destroyer of the Russian Navy. Being a Mahanian navy they are designed with improved seakeeping and range relative to the small ships of other navies.
