Voici une autre étude réalisée en 2005
avec SpringSharp.
Le but étant d'installer 3 tourelles triples de 28O sur la coque du Graf Spee
pour en faire un navire plus puissant... C'est POSSIBLE!!!

Fuel, ammunition & stores: 2 636 tons, 18.6 %
Miscellaneous weights: 40 tons, 0.3 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
20 053 lbs / 9 096 Kg = 29.9 x 11.0 " / 280 mm shells or 3.3 torpedoes
Stability (Unstable if below 1.00): 1.17
Metacentric height 4.1 ft / 1.2 m
Roll period: 14.9 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.83
Seaboat quality (Average = 1.00): 1.25
Hull form characteristics:
Hull has low quarterdeck
Block coefficient: 0.501
Length to Beam Ratio: 8.33 : 1
'Natural speed' for length: 24.42 kts
Power going to wave formation at top speed: 50 %
Trim (Max stability = 0, Max steadiness = 100): 56
Bow angle (Positive = bow angles forward): 6.00 degrees
Stern overhang: 11.65 ft / 3.55 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 23.29 ft / 7.10 m
- Forecastle (19 %): 20.67 ft / 6.30 m
- Mid (50 %): 18.70 ft / 5.70 m
- Quarterdeck (19 %): 10.70 ft / 3.26 m (18.70 ft / 5.70 m before break)
- Stern: 11.35 ft / 3.46 m
- Average freeboard: 18.12 ft / 5.52 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 111.0 %
- Above water (accommodation/working, high = better): 139.5 %
Waterplane Area: 28 434 Square feet or 2 642 Square metres
Displacement factor (Displacement / loading): 112 %
Structure weight / hull surface area: 142 lbs/sq ft or 693 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.96
- Longitudinal: 1.41
- Overall: 1.00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
