This thread is where I will post my designs for the Rheinland Kaiserliche Marine.

Here is the first design a battlecruiser of 1909.
I have not given her a name as of yet.

Here is a small SSK.

This actually looks like a really good start! Keep it up! :)

Btw, did you draw those turrets? If so, they look mighty good!

Thanks. :)

And Garlicdesign has drawn the turrets for his Derfflinger class.

It seems that You are learning! That's an interesting start. :)

Thanks.

Is there any issues with the design so far?

Well, the armour belt could be lower. ;) If you can find and mention RL examples from the same time period and rough size, I'll be willing to withdraw this argument though, since it's not as thick as your earlier ones have been.
Other than that, it looks fairly well. What ship served as main inspiration for this one, and what's your intended speed, armament, armour and size? If you have the rough datas, and they seem reasonable, I could do a springsharp report. :)

the armored belt is from the Nassau/Helgoland classes and the gun layout is basically the Seydlitz class's gun arrangement but with an extra turret forward all of which are 12 inch.

Speed should be similar to the most of the German battlecruisers.

Overall survivability and seakeeping ability:

	  41 507 lbs / 18 827 Kg = 47,9 x 12,0 " / 305 mm shells or 3,7 torpedoes
	Stability (Unstable if below 1.00): 1,20
	Metacentric height 6,4 ft / 2,0 m
	Roll period: 15,6 seconds
	Steadiness	- As gun platform (Average = 50 %): 61 %
			- Recoil effect (Restricted arc if above 1.00): 0,58
	Seaboat quality  (Average = 1.00): 1,22

Hull form characteristics:
	Hull has a flush deck,
	  a ram bow and a cruiser stern
	Block coefficient (normal/deep): 0,594 / 0,601
	Length to Beam Ratio: 7,12 : 1
	'Natural speed' for length: 25,89 kts
	Power going to wave formation at top speed: 51 %
	Trim (Max stability = 0, Max steadiness = 100): 50
	Bow angle (Positive = bow angles forward): -11,00 degrees
	Stern overhang: 0,00 ft / 0,00 m
	Freeboard (% = length of deck as a percentage of waterline length):
				Fore end,	 Aft end
	   - Forecastle:	20,00 %,  20,34 ft / 6,20 m,  20,34 ft / 6,20 m
	   - Forward deck:	30,00 %,  20,34 ft / 6,20 m,  20,34 ft / 6,20 m
	   - Aft deck:	35,00 %,  20,34 ft / 6,20 m,  20,34 ft / 6,20 m
	   - Quarter deck:	15,00 %,  20,34 ft / 6,20 m,  20,34 ft / 6,20 m
	   - Average freeboard:		20,34 ft / 6,20 m
	Ship tends to be wet forward

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 75,3 %
		- Above water (accommodation/working, high = better): 154,0 %
	Waterplane Area: 45 902 Square feet or 4 264 Square metres
	Displacement factor (Displacement / loading): 104 %
	Structure weight / hull surface area: 168 lbs/sq ft or 821 Kg/sq metre
	Hull strength (Relative):
		- Cross-sectional: 0,97
		- Longitudinal: 1,30
		- Overall: 1,00
	Hull space for machinery, storage, compartmentation is excellent
	Room for accommodation and workspaces is excellent
	Good seaboat, rides out heavy weather easily

Note that the conning towers have extreme armour becouse armour inserted to the aft conning tower slot isn't calculated for some reason... the actuall datas are 300mm fore CT, 200mm aft CT.
