A stab at small ships. Based on USS Texas (1892) the United State's first battleship. I take any helpful suggestions other than making it bigger.

[Jefgte]

Not a bad ship for coastal operations

suggests:
- reduce the thickness belt to 102-127max
- increase the lenght of the belt
- increase slightly the speed (20kts are short in 1913)
- increase the Lenght to Beam ratio
- with 20' the freeboard is certainly too high
- ...

Since her main armament is already 8", I'd consider losing the 6" guns for something a little smaller and handier, if you are worried about anti-torpedo boat armament.

if ya got em id say use 5" for secondaries, they are about as big as im comfortable with as a QF gun

I have schoolwork to do, so I'll fix it up later.

Yea, I noticed that part after I finished the design. I was going to change the guns to 5"-4" QFs

I was thinking of a certain ship while making it. I'll reduce belt to 127mm and increase the belt length to say 200ft (Just noticed that it didn't cover minimal engineering spaces).
I was going with the Battleship Texas for the dimensions (Just rounded the figures up) I saw no problem with the L:B ratio as I have planned for it to go at a relatively slow pace. I will lower the freeboard.

[The Rock Doctor]

What are the intended functions of this ship?  What opponents is it expected to fight?

[Logi]

Basically its a small ship that is designed to sink cruisers. If it were surrounded by enemy ships, it had to withstand the barrage while firing her guns (for some time) before sinking.

Btw: Rocky does the L:B ratio impact it a lot at 20kts? I'll change it to around 5.5:1 if its no good. I just figured at that speed, it wouldn't have much of an effect.

The problem is with that speed she is some very bad issues in a fight.  She can only outrun old VTE warships not even all of those.  A modern BB could run her down and then pound her into a wreck, let alone the AC/BC's out there. 

Now lets look at your stated mission cruiser killer.  She has the firepower and armor to take on protected cruisers but she is 7 to 10 knots too slow for ships of this generation.  She can't catch them and if they come after her in numbers she can't outrun them.  What you have here is a very small coastal defence battleship; however, you don't have a huge amount of firepower.

If you improve the B:L it will increase the speed you get on the same SHP and displacement. 

What I suggest you do is look back at your mission.  You want to kill cruisers, cruisers are fast so thats your first requirement.  So want 28 to 31 knots if you want to be faster than the fastest cruisers on the drawing boards / that have been laid down.  That might be hard on that displacement and have anything left over for weapons and armor.  If you push the displacement up could you afford to build it? 

Also looking at your tech  you can't build this ship anyways.  It requires 1904 BB/AC tech.  Its the 8" gun on a turret.

If you want a cruiser I suggest you settle for a straight forward light cruiser, armed with 6" weapons, 28 knots and some torpedo's.  If you want a firepower edge I suggest 7.5" weapons.  You should be able to fit 3 or 4 on 5,500 tons and still get a good turn of speed.

There are few things to note:
1. I'm not Ireland anymore, if I was I would have put a H1 report already.
2. Its really a design study, let's not complicate it with discussions about tech levels
3. I don't want a cruiser, I want a pocket cruiser :-\ Also, if I wanted to catch up with the fastest cruisers, I would build a speed freak. (Which wouldn't have much firepower)
4.

   Oil fired boilers, steam turbines,
   Direct drive, 4 shafts, 26,428 shp / 19,716 Kw = 20.18 kts

   Bunker at max displacement = 1,781 tons

If I went with the CSa battleship of 1912, its not that behind in speed.

Also, what's B:L? I was only aware of block coefficient and length:beam ratio.
Reconsidering my mission, i think i'll opt for more firepower. The slug it out ship. I'm also trying to avoid upping my ships displacement too much.

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

Major Modifications:
   +increased belt length to 230 ft
   +increased L:B ratio to 5:1 (increased length of ship by 20 ft)
   +increased max speed to 22.5 kts (also increased range)
   +added 4x18" torpedoes tubes submerged (20 torpedoes aboard)
   +increased number of main guns to 8 (2x4)
   +increased number of secondary by double (twin mounts)
   +increased number of MG by double (twin guns)
   -reduced belt thickness
   -lowered freeboard
   -decreased floatation from 10.5k to 7.7k (not intentionally)
   -reduced beam by 1 ft

my advice on ships Logi (having developed 2 compleatly diferent fleets for the sim) would be look at your potential oponents, think about how they fight, and think about what your objectives would be in a conflict.

Ill give you an example using the NS (I Know who I could be at war with instantly)

DKD: Armor and speed over firepower (under the previous player)
Austria: armor and firepower over speed
Spain: armor and speed over firepower
France: armor and firepower over speed (fighting them would be a bad idea but it could happen)
Maoria: armor and Firepower over speed
Netherlands: speed and firepower over armor

I am atempting to strike a balance of armor and speed over firepower (without hurting firepower to badly).  I would advise you to compile a list like this then let it guide you.

Like all my advice this is free unsolicited and can be ignored

not a bad CDBB honestly.
