Chyba mi się ten skośny wirus na mózg rzucił... Efektem jest taki oto okręt – japoński krążownik Ibuki, ale ukończony w postaci ciężkiego krążownika torpedowego, uzbrojonego w 80 wyrzutni „długich lanc”. Wyrzutnie zostały rozmieszczone głównie w poczwórnych stanowiskach na sponsonach wzdłuż burt oraz na pokładzie – trzy stanowiska na rufie i trzy na dziobie. Uzbrojenie artyleryjskie w związku z tym ograniczono do 8 dział 203 mm, likwidując jedną z wież dziobowych.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
12 468 lbs / 5 655 Kg = 48,8 x 8,0 " / 203 mm shells or 1,9 torpedoes
Stability (Unstable if below 1.00): 1,03
Metacentric height 2,9 ft / 0,9 m
Roll period: 16,5 seconds
Steadiness - As gun platform (Average = 50 %): 22 %
- Recoil effect (Restricted arc if above 1.00): 0,37
Seaboat quality (Average = 1.00): 0,30
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,558
Length to Beam Ratio: 9,82 : 1
'Natural speed' for length: 25,50 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 31
Bow angle (Positive = bow angles forward): 16,50 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26,94 ft / 8,21 m
- Forecastle (20%): 16,47 ft / 5,02 m
- Mid (50%): 16,47 ft / 5,02 m

- Stern: 14,47 ft / 4,41 m
- Average freeboard: 17,16 ft / 5,23 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 152,2%
- Above water (accommodation/working, high = better): -101,8%
Waterplane Area: 30 288 Square feet or 2 814 Square metres
Displacement factor (Displacement / loading): 107%
Structure weight / hull surface area: 123 lbs/sq ft or 601 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1,10
- Longitudinal: 0,96
- Overall: 1,00

Room for accommodation and workspaces is extremely poor
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability
