The alternate very large German battleship

I used the alternative dimensions that I had proposed on March 3, 1999, except that I reduced the draft considerably. Instead of a bizarre 45ft draft, the design fit nicely with a 38ft draft, which is too much, but better. The specifications, as revised, are as follows:

Dimensions:
1128ft x 144ft x 38ft, with

Coefficients:
Cp=0.686  Cm=0.95

Armament:

9-21in/45, 12-6in/50 QF, 44-40mm AA guns, 6-20mm AA guns

Speed=31 knots

Protection:

Belt=17in
Decks=7in + 4in
