Quick question: are the rules based on standard tonnage or normal? I assumed standard, but thought I should double check.

For a ´39er design she is rather heavily armed. Have you tried a deck plan to see if you can find enough deckspace for all those guns? Those large TT tubes eat up a lot of room and you have quite some AA mounts to place too. Add (two?) funnels, boats, searchlights, masts, bridge and enough room for her crew....
