That's some really nice info! I've heard speculation on the wind speed / boat speed ratios but yours is the first actual data I've seen. Great job!
I don't log any sailing info for the most part, but do record certain pedaling distances and speeds, since I do quite a bit of that. It really makes a nice reference base so if you want to try something different, you have a good way to evaluate your efforts.
This is apparent wind speed? What are your general impressions about speed at different points of sail? Where do you typically pick up your maximum? It seems I get my best steady speeds on a close / beam reach (in light chop), but my max speeds come in if I bear off a bit when a gust comes along. With more chop, I seem to do better on a broad reach, but then a GPS makes a poor substitute foe a sailing partner!
