Please remember to put your non-Wesworld designs in the proper folder.

Here are my two new passenger ships I designed for the White Star Line, the RMS Tectonic and RMS Jurassic . They are basically enlarged versions of White Star's 1907 Adriatic. (picture below)



******************************

I intended these two ships to team with the Olympic , so I designed them to make 21 knots with a potential maximum of 23 knots.

Here is the design report from Springsharp.

Operator: White Star Line

Builder: Harland & Wolff, Belfast, Ireland

Gross Tonnage: 34,000 gross tons (est.)

Displacement: 36,162 t light; 36,962 t standard; 39,990 t normal; 42,413 t full load

Dimensions: Length (overall / waterline) x beam x draught (normal / deep)
(759.00 ft / 732.00 ft) x 89.00 ft x (33.00 ft / 34.70 ft)
(231.34 m / 223.11 m) x 27.13 m x (10.06 m / 10.58 m)

Machinery:
Oil fired boilers, steam turbines,
Geared drive, 3 shafts, 55,000 shp / 41,030 kW = 23 kts max speed
Range 4,000nm at 21.00 kts service speed (@ 39,292 shp)
Bunker at normal / max displacement = 3,028 tons / 5,451 tons

Complement: 706 – 919

Cost: £3.628 million / $14.512 million (1920 dollars)

Distribution of weights at normal displacement:
Machinery: 1,923 tons, 4.8 %
Hull, fittings & equipment: 21,710 tons, 54.3 %
Fuel & stores: 3,828 tons, 9.6 %
Miscellaneous weights: 12,529 tons, 31.3 %
- Hull below water: 4,810 tons
- Hull void weights: 500 tons
- Hull above water: 4,590 tons
- On freeboard deck: 2,179 tons
- Above deck: 450 tons

Overall Survivability and Seakeeping:
Survivability (Non-critical penetrating hits needed to sink ship):
10,423.8 lbs / 4,728.1 kg = 96.52 x 6 " / 152 mm shells or 0.75 torpedoes
Stability (Unstable if below 1.00): 1.25
Metacentric Height: 6.3 ft / 1.9 m
Roll Period: 14.9 seconds
Steadiness - As gun platform (Average = 50 %): 61 %
Seaboat Quality (Average = 1.00): 1.96

Hull Form Characteristics:
Hull has a flush deck, a normal bow and counter stern
Block coefficient (normal/deep): 0.651 / 0.657
Length to Beam Ratio: 8.22 : 1
'Natural speed' for length: 27.06 kts
Power going to wave formation at top speed: 41 %
Trim (Max stability = 0, Max steadiness = 100): 31
Bow angle (Positive = bow angles forward): 4.50 degrees
Stern overhang: 24.40 ft / 7.44 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 20.00 %, 33.00 ft / 10.06 m, 29.00 ft / 8.84 m
- Forward deck: 30.00 %, 29.00 ft / 8.84 m, 27.00 ft / 8.23 m
- Aft deck: 35.00 %, 27.00 ft / 8.23 m, 27.00 ft / 8.23 m
- Quarter deck: 15.00 %, 27.00 ft / 8.23 m, 27.00 ft / 8.23 m
- Average freeboard: 28.02 ft / 8.54 m

Ship Space, Strength and Comments:
Space - Hull below water (magazines/engines, low = better): 42.5 %
- Above water (accommodation/working, high = better): 184.9 %
Waterplane Area: 49,955 square feet or 4,641 square metres
Displacement Factor (displacement / loading): 244 %
Structure weight / hull surface area: 279 lbs/sq ft or 1,361 kg/sq metre
Hull strength (Relative):
- Cross-sectional: 2.25
- Longitudinal: 3.21
- Overall: 2.33
Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Excellent seaboat, comfortable, rides out heavy weather easily

*Note : crew and damage values modified for merchant service.
