Another attempt at a "new age" armoured cruiser for 1905

I have been playing with 1905 style armoured cruiser designs for a long time. This version is rather like the Minotaur class, except for a uniform armament. I was able to achieve 24 knots, as well, thanks to turbines and oil fuel. I opted for superfiring guns, as well. Admiral Fisher had contemplated such a thing, but the very conservative navy rejected them at the time of the Dreadnought. This is my Springsharp report:

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   18,123 lbs / 8,220 Kg = 46.5 x 9.2 " / 234 mm shells or 2.9 torpedoes
