RE: [PSUBS-MAILIST] Need formulas please

Fly,

 

Thanks. I'll have to go back and find that posting. Perhaps I'm mistaken or misquoting.

 

Nonetheless, I'd like to have all of the formulas handy so that I can establish a greater level of confidence in my designs. Due to my lack of experience, trial and error gets more difficult. For example if my ballast tanks are too small, I've built myself strange surface boat :-)

 

Thanks,

Marten
