It looks really nice and suits this AU perfectly.

I've redrawn the torpedo tubes and K-guns that seem so prevalent on SB these days (despite the fact they are USN models!)

Use them if you like!

Thanks everyone :D

@PB - yeah I may have put effort into drawing scuttles that I should have put into drawing the prop shaft :lol: oh well...

@Colo - thanks for that, I'm too lazy to change this drawing at the moment but you may very well see them in future designs (I can just pretend it was too hard to source British equipment hence the USN models 8-) )

Given the scale, it could easily be a Thornycroft DC Thrower.

Miscellaneous weights: 75 tons, 3.6 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
624 lbs / 283 Kg = 11.9 x 4.7 " / 120 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.27
Metacentric height 1.7 ft / 0.5 m
Roll period: 11.7 seconds
Steadiness - As gun platform (Average = 50 %): 61 %

Seaboat quality (Average = 1.00): 1.21

Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0.332
Length to Beam Ratio: 10.15 : 1
'Natural speed' for length: 19.23 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 20.00 degrees
Stern overhang: 1.50 ft / 0.46 m
Freeboard (% = measuring location as a percentage of overall length):

- Stern: 12.46 ft / 3.80 m
- Average freeboard: 14.46 ft / 4.41 m
Ship tends to be wet forward

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 163.5 %
- Above water (accommodation/working, high = better): 117.4 %
Waterplane Area: 8,232 Square feet or 765 Square metres
Displacement factor (Displacement / loading): 83 %
Structure weight / hull surface area: 38 lbs/sq ft or 188 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.48
- Longitudinal: 1.79
- Overall: 0.54
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate
Good seaboat, rides out heavy weather easily

TT's in a quad centerline mount. Miscellaneous weight includes 2 DCT's and 2 DC racks.

Design works well with a little excess hull strength left over.

Thanks for that, I'm glad it works out well :)

In Wesworld we never design a destroyer in SS with a cross-sectional lower than 0.50. That is our minimum regardless of the overall.
Looks good otherwise though.

you guys go down to 0.5? I thought 1 was a good benchmark for everything except FACs and really flimsy craft

SS2 allows 0.51 hull strength for DD's and smaller without hull strain, getting a 1.0 for a DD is pretty much impossible...

The largest ships in the Recherche Navy at the outbreak of World War 2 - the Recherche class 'battlecruisers':

This one took me some time to arrive at a design I liked, I looked at concepts sizing from ~19,000t up to 28,000t with 12in guns before settling on a middle ground. I think I'm stretching the Navy a bit with these budget and manpower wise but I can justify it by saying it's an AU :lol:
