:lol: good comeback, matey! Just deepen the hull and increase draught and you'll also raise the metacentric height, thus making her more stable!

I can't see any wing 8" guns... they're 6". :) And a 6" shell is what is usually considered (to my minor knowledge) the biggest caliber shell to be effectively handled with only hands.

3) Yes, I felt so as well, but I have no idea of what to put on. Maybe a small CoA? If I knew the Wrangel family's crest I would smack it up there, but as it is now... yah. I'll figure something out. :)
Sorry about mistaking the bore of the gun, they looked mighty big to be 6"!
And yeah, the 100-ish pound shell of the 6" gun is the biggest that anyone believed that two men could manage.

AS far as the stack, I was thinking that they looked a bit bare- they needed funnel caps, some miscellaneous pipes, supports, etc on them... not so much that they needed artwork. 8-)

If you need one, I think I can get you one, that is badge, since I did a Swedish Type22 variant named Wachtmeister and Wrangel...look in personal designs...

1.) There is no anti-torpedo boat armament, and that would be a very bad thing to omit on this ship. A few (4-5) elevated 3" guns placed to fire on each beam would suffice.
Forgot to mention it... but...:

The red markings show you the ATBW armament. I will buff up the numbers, but there ARE some at least. :)

Much better hull proportions!

Updated, mostly the little 'walkway' at the stern and a new color scheme.

Looking good, think I'll take a stab at doing up an SS2 profile. Is there a laydown date or any other information? I'm thinking four 8.27-inch guns (twin turrets) plus 4 single 6-inch guns.

I haven't decided on an exact date, but say 1905-1910. FYI, there are only two 8.27"(single turrets). Otherwise, be my guest, and have fun. :)

Miscellaneous weights: 75 tons, 1.2 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
3,902 lbs / 1,770 Kg = 13.8 x 8.3 " / 210 mm shells or 0.7 torpedoes
Stability (Unstable if below 1.00): 1.18
Metacentric height 2.3 ft / 0.7 m
Roll period: 13.5 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0.76
Seaboat quality (Average = 1.00): 2.00

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.568
Length to Beam Ratio: 9.37 : 1
'Natural speed' for length: 21.43 kts
Power going to wave formation at top speed: 44 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -12.00 degrees
Stern overhang: -5.20 ft / -1.58 m
Freeboard (% = measuring location as a percentage of overall length):

Ship tends to be wet forward

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 145.2 %
- Above water (accommodation/working, high = better): 178.5 %
Waterplane Area: 15,975 Square feet or 1,484 Square metres
Displacement factor (Displacement / loading): 98 %
Structure weight / hull surface area: 82 lbs/sq ft or 400 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.91
- Longitudinal: 2.33
- Overall: 1.00
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Design works well but couldn't fit a torpedo bulkhead and the belt is shorter than I'd like. A bit more speed would also be nice.
