Still toying around with a "Heavy" cruiser idea.

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     17,457 lbs / 7,918 Kg = 61.8 x 8.3 " / 210 mm shells or 1.9 torpedoes
   Stability (Unstable if below 1.00): 1.10
   Metacentric height 3.5 ft / 1.1 m
   Roll period: 15.6 seconds
   Steadiness   - As gun platform (Average = 50 %): 69 %
         - Recoil effect (Restricted arc if above 1.00): 0.52
   Seaboat quality  (Average = 1.00): 1.12

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.528
   Length to Beam Ratio: 9.49 : 1
   'Natural speed' for length: 25.62 kts
   Power going to wave formation at top speed: 53 %
   Trim (Max stability = 0, Max steadiness = 100): 62
   Bow angle (Positive = bow angles forward): 13.50 degrees
   Stern overhang: -3.28 ft / -1.00 m
   Freeboard (% = measuring location as a percentage of overall length):

      - Mid (50 %):      19.69 ft / 6.00 m
      - Quarterdeck (15 %):   19.69 ft / 6.00 m
      - Stern:      19.69 ft / 6.00 m
      - Average freeboard:   20.18 ft / 6.15 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 95.3 %
      - Above water (accommodation/working, high = better): 178.4 %
   Waterplane Area: 31,016 Square feet or 2,881 Square metres
   Displacement factor (Displacement / loading): 110 %
   Structure weight / hull surface area: 119 lbs/sq ft or 580 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.99

      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is adequate
   Room for accommodation and workspaces is excellent

I just test Guinness, the possibility to built 30kts  AC in a 170m SW.
If the 170m ship could'nt obtain 30kts with correct armament, I don't built her.

Actually, with the technos, it's very hard & perhaps impossible...


Jef

Not true, Jef. When I was Romania, I create plans for Romania to build a 30.3 knot cruiser on 10,000 tons. It mounted 6 9.2'' guns, and 8 5'' guns. It was built using 1912 engines. So yes, Jef, it is possible. The problem was that it had a very short range and a 6'' belt, but still.

Thanks Texan  ;)

Work is not finish...

*waves hand*
These 240mm weapons are the guns you're looking for.

:p

Is this a JMT (Jedi Mind Trick)?

[The Rock Doctor]

It seems the Force was weak in that one.

[Sachmle]

Well....

These are not the triple turrets you are looking for....

[TexanCowboy]

Bigger is not always better

[maddox]

Size of guns ain't everything.

A devestating salvo of torpedo's can achieve the same goal.

[TexanCowboy]

You didn't comment on the tri-color glow effect... :'( ;D ;D ;D

I would actually go out on a limb here and say that a heavy cruiser in the German battlecruiser style would be better.    Armour=Speed>Armerment
