I think that 3x3,5 inches is more evolutionary upgunning from the 2x3" of my previous class, than 2x4". And fits the OTL KM GTB1913 which I base my designs on better ...

Besides the apparent need to develop a 3.5" gun (which would take two years), the ship design is on the poor side. Undergunned, slow, and short-ranged, especially for oil-firing. The cause is the 12' freeboard -should belong to a cruiser not destroyer.

An increase of cruising speed, and doubleing the bunkerage produces a drop in Light and Standard displacement ...

P3D · August 04, 2008, 03:48:39 PM

That 50t spare should go into increasing seakeeping to 1.00 - especially as you now have 2kts more speed, which is not bad. Lengthen hull and slightly increase forecastle - I'd also add a third 4", and some misc. weight.

Err.. What is strange about that?
As springsharp uses normal displacement as baseline, of course standard and light will drop if one increase the proportion of fuel (that do not count towards light) in the normal displacement.

This "faster ship weighting less" somehow reminds of the logic used by the Bard here:

Korpen · August 10, 2008, 10:00:54 AM

About all the designs: whould it not a be a good idea to raise one gun mount so that the forward gun can fire over the very high forecastle?

Borys · August 10, 2008, 10:19:54 AM

Ahoj!
You are correct about the original design.

However, as to the later ones:

QuoteHull form characteristics:
Hull has a flush deck
Block coefficient: 0,465
Length to Beam Ratio: 10,44 : 1
'Natural speed' for length: 16,94 kts
Power going to wave formation at top speed: 69 %
Trim (Max stability = 0, Max steadiness = 100): 81
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: 18,00 ft / 5,49 m
- Forecastle (5%): 15,00 ft / 4,57 m
- Mid (50%): 8,00 ft / 2,44 m
- Quarterdeck (15%): 8,00 ft / 2,44 m
- Stern: 8,00 ft / 2,44 m
- Average freeboard: 9,99 ft / 3,04 m
Ship tends to be wet forward

In SS I input the same freeboard for 12 and 11 - which gives me a flushdeck description. I believe this to mean a gradual decrease from 11 to 9.
And as the guns are never placed on the Forecastle (you pointed that out to me), I imagine the fore gun to be just aft of the "11" point, and thus capable of firing forwards.
This is what I think (hope) my ship looks like:
http://www.german-navy.de/kriegsmarine/ships/torpedoboats/flottentorpedoboot1939/t22/index.html

Am I doing something wrong? Should I repeat the "11" value at "9" as well, as to get a "break fore of midpoint" description? I believe the below design to be a "break fore of midpoint" ship?

Hope is a horrible thing. ;)
Going by the freeboard numbers the ship is not flush decked, and i have no idea why springsharp says so, might have something to do with the very short forecastle. If one is seeking a gradual lowering flush deck I think the best way to handle that is by simply set the one height for 11&12, a bit lower for 8&9 and lowest for 5&6 (or 2).
Basically go by the numbers and do not give a damm what springsharp say about raised or flushed. ;)

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 175,8%
      - Above water (accommodation/working, high = better): 80,9%
   Waterplane Area: 5 151 Square feet or 479 Square metres
   Displacement factor (Displacement / loading): 60%
   Structure weight / hull surface area: 24 lbs/sq ft or 119 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,50
