Eric...
Thank you for pointing this out to me. Yes - it looks promising.
Main difficulty will be collecting data only when appropriate - avoiding data while tacking etc. and when the tide is distorting things. (Also I will need to thin densely-recorded data down before using in my published track log.)
I'll give it a go - in fact I have some historic track data I can use to develop the spreadsheet work. But for real data I will need to switch to true wind, which is trivial.
thanks, Tony
