Fictional Canadian Passenger Liner Design

After looking through the 'merchant ship designs' section of Wesworld, I have been tweaking around with SpringSharp to try to figure out how to sim my passenger liner with more "accuracy" by looking at other people's designs. This is my latest effort.

MS Canada, Canadian Proposed Passenger Liner laid down 1950

Displacement: 24,058 t light; 24,690 t standard; 31,610 t normal; 37,146 t full load

Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
(805.05 ft / 775.00 ft) x 89.00 ft (Bulges 89.50 ft) x (29.00 ft / 33.03 ft)
(245.38 m / 236.22 m) x 27.13 m (Bulges 27.28 m) x (8.84 m / 10.07 m)

Machinery:
Diesel Internal combustion generators,
Electric motors, 4 shafts, 120,000 shp / 89,520 Kw = 31 kts
Range 8,421nm at 27 kts (service speed)
Bunker at max displacement = 12,456 tons

Complement: 592 - 770

Cost: £9.725 million / $38.902 million (1950)

Distribution of weights at normal displacement:
Armament: 0 tons, 0.0 %
Machinery: 2,871 tons, 9.1 %
Hull, fittings & equipment: 9,887 tons, 31.3 %
Fuel, ammunition & stores: 7,552 tons, 23.9 %
Miscellaneous weights: 11,300 tons, 35.7 %
- Hull below water: 5,000 tons
- Bulge void weights: 800 tons
- Hull above water: 2,500 tons
- On freeboard deck: 2,000 tons
- Above deck: 1,000 tons

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
7,726.7 lbs / 3,504.8 kg = 71.54 x 6 " / 152 mm shells or 0.54 torpedoes
Stability (Unstable if below 1.00): 1.23
Metacentric height 6.2 ft / 1.9 m
Roll period: 15.1 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 2.00

Hull form characteristics:
Hull has low quarterdeck , a normal bow and a round stern
Block coefficient (normal/deep): 0.550 / 0.568
Length to Beam Ratio: 8.66 : 1
'Natural speed' for length: 27.84 kts
Power going to wave formation at top speed: 49 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 21.60 degrees
Stern overhang: 15.00 ft / 4.57 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 15.00 %, 38.00 ft / 11.58 m, 36.00 ft / 10.97 m
- Forward deck: 30.00 %, 36.00 ft / 10.97 m, 33.50 ft / 10.21 m
- Aft deck: 45.00 %, 33.50 ft / 10.21 m, 33.50 ft / 10.21 m
- Quarter deck: 10.00 %, 26.00 ft / 7.92 m, 26.00 ft / 7.92 m
- Average freeboard: 33.62 ft / 10.25 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 56.4 %
- Above water (accommodation/working, high = better): 263.3 %
Waterplane Area: 48,137 Square feet or 4,472 Square metres
Displacement factor (Displacement / loading): 185 %
Structure weight / hull surface area: 121 lbs/sq ft or 589 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.93
- Longitudinal: 1.99
- Overall: 1.00
Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, rides out heavy weather easily

Notes:
* Actual bunkers 4976 tons normal, 8456 tons max.
* Cruising range with normal fuel load is 6000 nm
* Damage and crew values divided by 10 for merchant service
* Actual full-load displacement: 35,591 tons (Cb = 0.563)
* Fulll load draft is actually 31.9 ft, corresponding with previous "actual" full load displacement figure.
* 4000 tons low-stowed cargo simmed as extra fuel (8456 + 4000 = 12456)

misc weight breakdown:
* 11,300 tons allocated for passengers and public facilities on the liner

If anyone can give me tips to help me sim liners better, I would love to hear them :)
