Have a look at TacticTool at http://www.nauticis.com/html/tactictool.html

Willem,
seems really something very usefull and very near to what I'm looking for.
I've big trobles on my pc (hope monday I can have che HD changed) so I'm not
downloading the beta.

Can it be feeded with nmea prerecorded file?
I know it's quite punishing but... wind data can be fed manually?

Pls, can I know the price in email?

Thanks.
Alberto.
