Hello Michal,
I purchease SailfishYactAnalyser (1.07 ver) in december 2001.
I have some problems with the parametric analysis, the spreedshits and graph are wrong.
The speed polar have also some bad values( inflectio of the curve).
And it's also heavy to translate SI units in US units.
I send a mail to techsail, they promise a new release for the end of 2001 and it seems more difficult to do than they says...
I try to download PCSAIL to compare the answers, but it seems not possible, only online ?
Phil
