Is there any other information on these designs (dimensions, secondary armament, armor, speed)?

Thanks!

I took a shot at the high-speed cruiser, using the earlier but similar AC Bayan (same Main Battery but eight 6-inch guns in wet casemates). Will probably need some tweaking...

I think too high block coefficient. In real-Bayan at the sizes of 137x17.5x6.7 meters displacement was 7330 tons.
For tower cruiser with linearly elevated towers, I think we should increase the length of the hull to 150 - 160 meters.

Thank you! We tried

And other than speed @ 36,000shp it specs almost exactly as you've written. I had to guess at things like deck/belt heights, belt lengths, but IMHO not to shabby.

I'd say one raised mount at best.

Getting close to a full battlecruiser with that one! Add another turret and boost the speed to 27 knots and she'd be a full-blooded BC.

As per the Springsharp User Guide, ships such as Dreadnought and this, with a raised forecastle deck with the A turret at that deck height require that A turret be listed as raised as well.

Cross-decking aside, I'd say she's a pretty good match for Invincible as is and would destroy any other "armoured cruiser" quite handily.

User's Guide is correct, but that's pretty clearly the main deck, not a raised forecastle. Dreadnought had a very long raised forecastle, but it was under 40% of the ship's length. This ship has 65% of the deck length at that height, so it's the main deck, and C Turret is on a low quarterdeck. So one raised turret, not two.

Fair enough, fixed.
