This is my (almost) exact copy of the Lusitania.  I need troop transport capabilities as well as the ability to transport immigrants to all my new colonies.

Another thing to note: at this point, our ports cannot build ships larger than 25,000 tons normal, so Lusitania, Titanic, or Imperator-sized ships are not allowed.

   Ship has slow, easy roll, a good, steady gun platform
   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Miscellaneous weight accounts for 6 (1 forward, 1 aft, 4 broadside) submerged 450mm/5m torpedo tubes and 12 reload torpedoes.

The armor scheme is laid out to provide 2m of main belt coverage below the water line, 4m above waterline, with the upper belt protecting the casemates of the 12" guns.

Switching the guns to 10" vs 12" will help the rate of fire issues that would arise from a casemate mounting (the 10" shells would be easier to handle).  Making this switch allows the draft to be reduced to 8m.
