Re: [PSUBS-MAILIST] Hull Design Programs

[Ian Roxborough <irox@ix.netcom.com>]

I'd be interested to hear from anybody who thinks they are getting
useful results from those programs.  I tried them a while ago, but
the results I was getting from the programs where nothing like the
results I was getting from the formulas.  Since there wasn't any
source code to these programs I wasn't able to work out if it was
an implementations problem,  a unit issue (working in mm or inchs
and kg, instead of meters and kg, etc.), or if I'd done something
really wrong then working out the formula.
