It doesn't appear that anybody's noticed that the TBD is _way_ too thick and there is _no_ deck armor. Did a quick SS2 fixing these problems...

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
15,424 lbs / 6,996 Kg = 36.6 x 9.5 " / 240 mm shells or 4.7 torpedoes
Stability (Unstable if below 1.00): 1.03
Metacentric height 2.2 ft / 0.7 m
Roll period: 15.8 seconds
Steadiness - As gun platform (Average = 50 %): 65 %
- Recoil effect (Restricted arc if above 1.00): 0.66
Seaboat quality (Average = 1.00): 1.31
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.759
Length to Beam Ratio: 5.59 : 1
'Natural speed' for length: 17.65 kts
Power going to wave formation at top speed: 52 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 15.00 degrees
Stern overhang: 3.28 ft / 1.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 16.40 ft / 5.00 m
- Forecastle (20 %): 14.76 ft / 4.50 m
- Mid (50 %): 13.12 ft / 4.00 m

- Stern: 14.76 ft / 4.50 m
- Average freeboard: 13.95 ft / 4.25 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 63.6 %
- Above water (accommodation/working, high = better): 101.1 %
Waterplane Area: 14,672 Square feet or 1,363 Square metres
Displacement factor (Displacement / loading): 110 %
Structure weight / hull surface area: 102 lbs/sq ft or 498 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.92
- Longitudinal: 2.13
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate
Good seaboat, rides out heavy weather easily
Made the following corrections:
- Changed gun layout to match drawing
- Reduced TBD from 10-inches down to a more reasonable 2.5-inches
- The 3-inch DP mounts are now enclosed in armor
- Added a 4-inch deck (deck armor missing on all designs)
