german battleship laid down 1934

this is my 2nd ever spring sharp design posted here for your consideration and scrutiny

took most of the armor values from the real life battleship bismarck with some slight adjustments as well as some hull form characteristics

simmed in ss3b3

soooo you want to make hull strength lower? that seems counter intuitive?

and freeboard would improve seakeeping i assume?

decrease torpedo bulkhead wat would u recommend?

ah i see i wasnt sure what average hull strength would be so i assumed anything less than 2.00 a was weak

as for torpedo buldge i couldnt find the specific figure in my design charts of bismarck so i just guessed

my revised verision of Bayern 1934 with the improvements suggested by desertfox

still a tad big and high hull strength but i trimmed it down a little and added another set of dual 4.10" secondary DP mounts, trimmed down torpedo bulkhead, increased freeboard, buffed up armor protection in all areas, speed remains the same as this is a battleship

hehehe thanks for the tips guys i will take this into consideration on my next design

cheers
