Niespodzianka - rysunek jest tylko moim zobrazowaniem autentycznego projektu z 1906 r. (wykonanym zresztą przy pomocy szkicu z jednej książki - dzięki Maciej3:) ). Faktem jest jednak, że wpływy "popowek" są w nim dość wyraźne - autor miał swój udział w projektowaniu m.in. carskiego jachtu Liwadia, który również miał nadzwyczaj dużą szerokość w stosunku do długości, i kształt jeszcze bardziej bliski "popowkom". Parę słów więcej na temat tego projektu napisałem na swoim blogu:
http://springsharp.blogspot.com/ Tam też obliczone w springsharpie przybliżone dane jednostki, dość dokładnie odpowiadające danym projektowym podawanym w literaturze. Odnośnie poruszanej tu kwestii napędu, to mamy 4 śruby i łączną moc ok. 40.000 KM, czyli dość sporą w porównaniu z innymi drednotami, choć tak na intuicję - nie jestem do końca przekonany, czy przy tych proporcjach kadłuba to by wystarczyło?
ps. cieszę się, że rysunek się podoba:)
ps2. o innych wariantach kolorystycznych też pomyślę:)

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
22 670 lbs / 10 283 Kg = 26,2 x 12,0 " / 305 mm shells or 4,0 torpedoes
Stability (Unstable if below 1.00): 1,44
Metacentric height 11,6 ft / 3,5 m
Roll period: 14,2 seconds
Steadiness - As gun platform (Average = 50 %): 42 %
- Recoil effect (Restricted arc if above 1.00): 0,13
Seaboat quality (Average = 1.00): 0,71
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,572
Length to Beam Ratio: 4,01 : 1
'Natural speed' for length: 21,45 kts
Power going to wave formation at top speed: 57 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -9,00 degrees
Stern overhang: 0,98 ft / 0,30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 17,45 ft / 5,32 m
- Forecastle (14%): 16,96 ft / 5,17 m
- Mid (50%): 16,01 ft / 4,88 m
- Quarterdeck (14%): 14,96 ft / 4,56 m
- Stern: 15,45 ft / 4,71 m
- Average freeboard: 16,04 ft / 4,89 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 122,8%
- Above water (accommodation/working, high = better): 128,9%
Waterplane Area: 37 657 Square feet or 3 498 Square metres
Displacement factor (Displacement / loading): 96%
Structure weight / hull surface area: 172 lbs/sq ft or 839 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,98
- Longitudinal: 1,79
- Overall: 1,04
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
