RE: [PSUBS-MAILIST] Hull Calc Spreadsheet
As the
author of that spreadsheet, let me be the first to say there are guarantees!
I did however enter data in the spreadsheet that was calculated
independently by other individuals, and found the results
matched quite closely. However, bear in mind that most of the formulas are
empirical and have significant deviations. Then there's things like fabrication
problems, material imperfections, etc. Bottom line, I'm using a safety factor
of 3 in my design, which is well above what would be used in the commercial
or military field.
If you
are interested in the formulas behind the spreadsheet, contact me offline and
I'll get you scans.

How accurate has anyone proved
the spreadsheet to be that is available for download on PSUBS ? I am just
curious if anyone has REALLY run any tests on it. Also I am not basing my sub
on its results and yes I am having it engineered I was just curious if an
engineer has checked it out.... I ran some interesting results on the CBUG II
Im working on so thats why Im asking.....
Thanks
