She's designed well inside the limitations.  She's merchant standard.

Yeah, that's what I was assuming. I missed the costs line at the bottom of the report when I copy/pasted it though, which I fixed above.

The rules for auxiliaries(assuming you want to pay merchant rules $$$) are taking a bit more effort to get my head around.

Can I order a few of each too?

Maybe. :)

I need to figure out what I'm building in 1915-1916 now that the business in Africa is over...

[Guinness]

Two design studies for the next two classes of Confederate Torpedo Rams. The first is a study for a new class of leaders, designed to allow the commander of a TR squadron and his (meager) staff a little more room to work, and more importantly, large enough to ship a long-range wireless set. The second is the design for a successor to the E-Class fleet Torpedo Rams. Both would ship the new 4.75" 50-pounder gun, with the leader carrying twin mounts as well.

Armament:

     Quick firing guns in deck mounts

I'm guessing that's supposed to be A(Twin) X(Single) Y(Twin)?

I'm guessing that's supposed to be A(Twin) X(Single) Y(Twin)?

Correct, subject to whether or not I draw it and it looks funny :)

At least so far, Confederate thinking leans toward symmetrical armament fore and aft, with any extra gun or guns aft. The thinking is that the extra gun or guns would be of more use when turning away from a torpedo attack then when trying to fight through one.

I'm also thinking about designs with two singles in A and B positions superfiring, with a twin in X superfired by a single in Y, and something more like the classic US arrangement of 5 single mounts. Both would cost reserve weight and a little stability.

[The Rock Doctor]

Some Japanese designs did the twin---single/twin thing and looked okay.

What about the German layout of twin forward, three singles aft?

Both designs look good even though they aren't 1,500 t max-sized boats.

I'm not sure about three singles aft, as I suspect the arcs may be less efficient. I also did a 6 gun (3 twins with two mounts at either end, or 2 twins and two singles symmetrical) which is just barely (a hundredth of a knot) slower and 25 tons heavier. That feels like overgunning though.

As far as the 1500t limit: This started as an exercise to see how much boat I could get by modifying the E-class, so I see both as a natural evolution. I expect the CSA will nose up to the 1500t limit soon enough though. For now, saving 300ish tons or more a boat means I can build more boats :)

Twin mounts must be in mount and hoist:

Twin gun mounts requires hoists, and they are power operated.

This gives them more then twice the weight per barrel compared to singles, so IMO not worth it unless you want more then six guns.

[Guinness]

Bah! Another rule that's not 100% accurate historically...

The only reason I'd opt for twins here is to shorten length required to save some deck space and avoid superfiring forward. :(

   Stability (Unstable if below 1.00): 1.23
   Metacentric height 1.4 ft / 0.4 m
   Roll period: 11.9 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.20
   Seaboat quality  (Average = 1.00): 0.81

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 191.6 %
      - Above water (accommodation/working, high = better): 80.8 %
   Waterplane Area: 7,473 Square feet or 694 Square metres
   Displacement factor (Displacement / loading): 56 %
   Structure weight / hull surface area: 30 lbs/sq ft or 144 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 0.94
      - Overall: 0.53

If you want ahistorical gun arrangement, what's the problem with that?
