Software for ship modelling

[NickD]

Hello,
a long time ago, i've saw a little program, which can be used for WW2 ship modelling.
You can input dimensions, armament, engines, armor etc... and this software calculates displacement of the ship, seafaring characteristics, speed etc...
Everything was in text only.
The problem is i totally forgot the name of the software, and now it is impossible to find it.
Is someone seen such program? Or something similar?
