Anyone using Excel for working out their submarine math? I don't use excel, but open office, a freeware package that is very similar to Microsoft office (downloadable online). The excel equivalent part of the package is called calc, and it looks and works almost identically to the Microsoft package, only you don't have to line Mr Gates pocket. The attached image shows a few formulas for different parts of model sub design which I punched in from Norberts book, Model Submarine technology. Takes away the grind, especially if you want to quickly try different materials, volumes etc. It's very much a case of rubbish in rubbish out, so you need to be careful you are punching in the right numbers, but considerably less room for error than using a calculator I think.
