On the DDL, I'd suggest that if you have enough tonnage for 16 (!) 115mm guns, you should look at heavier weapons instead.

On the CL, I would suggest that 4 21cm guns is NOT a good choice in a design of this type.

IMO the first one with DP weapons makes for a cheap AA protection platform.

In the second one I have to agree they are too weakly armed to last too long vs the majority of the ships around.

Whats wrong with the 21 cm guns?

IMO not enough of them plus no protection for vitals.

And looking at the first design I would put a little bit of protection to the hull of the first design.

Slower rate of fire with 8" guns over 6" guns means that they could be killed by most 6x6" CLs (IMHO).

Much better. I'd be a bit concerned about the top weight on the DDL, it might work better to go to a Wyoming-style arrangement of the main battery, but all in all much better.

What is a Wyoming arrangement?

USS Wyoming had 6 main battery turrets, 2 forward and 4 aft, with 3 deck level and 3 raised turrets. See here for some pictures: http://www.maritimequest.com/warship_dir…yoming_bb32.htm

Makes sense. reduces the weight and helps the ship strength.

Makes sense for broadsides but wouldnt it lead to alot of dead angles for DP guns?

true but IMO makes for a better ship by reducing the top weight problem.

For low-altitude attackers approaching from directly ahead or astern, yes. On any other angle, not really. And, if there ARE low-altitude attackers (ie, torpedo bombers at this time period) executing a star-pattern attack on a ship of this size, the guns that are masked directly ahead or astern can engage targets on the beam.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
4 786 lbs / 2 171 Kg = 103,1 x 4,5 " / 115 mm shells or 0,9 torpedoes
Stability (Unstable if below 1.00): 1,06
Metacentric height 1,8 ft / 0,5 m
Roll period: 14,6 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0,51
Seaboat quality (Average = 1.00): 1,19

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0,435
Length to Beam Ratio: 10,00 : 1
'Natural speed' for length: 24,66 kts
Power going to wave formation at top speed: 62 %
Trim (Max stability = 0, Max steadiness = 100): 59
Bow angle (Positive = bow angles forward): 0,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 29,53 ft / 9,00 m
- Forecastle (20 %): 22,97 ft / 7,00 m
- Mid (50 %): 22,97 ft / 7,00 m (13,88 ft / 4,23 m aft of break)
- Quarterdeck (15 %): 13,88 ft / 4,23 m
- Stern: 13,88 ft / 4,23 m
- Average freeboard: 18,95 ft / 5,78 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 115,1 %
- Above water (accommodation/working, high = better): 116,7 %
Waterplane Area: 13 809 Square feet or 1 283 Square metres
Displacement factor (Displacement / loading): 114 %
Structure weight / hull surface area: 79 lbs/sq ft or 384 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,89
- Longitudinal: 2,80
- Overall: 1,00
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform

Actually, for ships of this size, under the Design Rules for Gentlemen, you can go down to 0.75 composite strength without ACTUALLY having a weak hull. So you can save some tonnage there.

Also, 150 shells per gun is probably not enough for a relatively rapid-firing gun like a 4.5". I'd suggest at least 270 rpg, probably more than that.

So you can ignore the caution strained hull warning?

As long as the composite strength is 0.75 or greater, yes, just like you can on destroyers and other smaller vessels.

OK, good to know
