COOL DRAWING!


The Royal shipyards in Durban offer variants of either the Fenris or the Diana classes that feature the gun and torpedo calibers requested.

The drawing is very nice.

The forward 75mm mounts seem very cramped though.

Great Drawing. Unfortunately, i can't make drawings like this one. Perhaps Gravina would also draw chinese vessels ?

Btw, when looking at the picture more closely I noticed your side mounted torpedo tubes.

Well, the beam of your ship is only 11,5m but you´re using 24" TTs which are most likely about 8 to 9 meters long, their tubes a bit longer. So even if mounting the turntables at the very edge of that ships deck you will need about 5meters inboard to actually turn those tubes. With two such sets on either side that leaves you only 1 to 2 meter(s) of space between those launchers. That´s not very much room for your funnel uptakes or aft superstructure.... :o(

to tell the truth I didnt think about the TTs, I was just happy to have gotten a nice picture since I suck at drawing ships

Tried to modify the drawing, but again I suck at this


(Original drawing Gravina, modification by me)

A powerful little ship.

He has expressed his willingness but that it may take a bit of time to fulfill requests

On the Persian version, you have triple 6" with moderately armored gun houses using mount and hoist mounts. That's a great deal of weight not to have a turret and barbette mount. I think it was over on a Siamese ship the same issue came up, but that was for twin turrets. It seems there were historic mount and hoist twins- such as on the Omaha class, but with very light armor, while other twins were turrets.

Modified design posted

One other thing- just glancing at other cruisers, I am a little worried about the internal beam. Konigsberg was a triple 6, and had 15.3m, there were several twins about that etc.
Perhaps you can find a IJN or other vessel to serve as precedent for the 11m internal beam, don't have the tme to poke about more right now.

Did a quick look but couldn't find anything. Konigsberg's probably the narrowest you can find.

Stern overhang: 1.00 ft / 0.30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26.50 ft / 8.08 m
- Forecastle (20%): 20.15 ft / 6.14 m
- Mid (60%): 20.15 ft / 6.14 m (12.15 ft / 3.70 m aft of break)
- Quarterdeck (15%): 12.15 ft / 3.70 m
- Stern: 12.15 ft / 3.70 m
- Average freeboard: 17.46 ft / 5.32 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 153.9%
- Above water (accommodation/working, high = better): 74.1%
Waterplane Area: 13,913 Square feet or 1,293 Square metres
Displacement factor (Displacement / loading): 93%
Structure weight / hull surface area: 42 lbs/sq ft or 205 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.50
- Longitudinal: 1.04
- Overall: 0.54
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily

Both of those would be weak-hulled, the breakpoint for the 0.50 strength is 3,000 tons STANDARD displacement.

As far as I know, we were supposed to deal with LIGHT and not STANDARD displacements when it comes to the HS rules.

I'd submit that all of these designs are overkill for general-purpose escort functions - especially given your limited ability to repair ships larger than 120 m.

I'd be curious if the gang can put 3x2 130mm, eight fish, 34 knots, and the required range on a 120 m long hull of not more than 2,000 t light.

Actually, none of the hull strength rules (from the Design Rules for Gentlemen) are light displacement, they're all standard displacement. Here's a copy of them:

Point 1: Hull strength.
a) Relative composite hull strength should not drop below 1.00 except for the light fast combattants (<6000 tons standard; >24kn)
b) Relative cross-sectional hull strength of light fast combattants of 0-3,000 tons standard should not drop below 0.5
c) In general, light fast combattants of 3,0001-4,500 tons standard can have a minimum relative composite hull strength of 0.75 as long as it does not cross the limit as given in point 1b.
d) In general, light fast combattants between 4500 tons and 6000 tons standard can have a minimum relative composite hull strength of 0.9
