was made using my Garmin tracks, AutoCAD 2000, and some notes taking during
the sail.

Why are you doing so much better
on Port tack than Starboard???

Difference if probably due to inexperience and me paying more
attention to speed than direction


Gotcha. Most boats sail a little differently on one tack than the
other. Not usually *that* differently though without extenuating
circumstances.
Seawards are nice looking boats. I've never sailed one though.
Maybe I'm wrong but I think there are GPS's on the market that will do
what you'd like to do in real time. IOW, plug in your windward mark as
a way point and the GPS will take speed and heading into account to
figure out velocity made good towards the mark. I don't know if you
can find one that'll take wind direction into account though so you
may need a steady wind direction, depending on what exactly you're
trying to analyze.
Joe's right though about just getting more time under sail. There's no
substitute for that. A little high tech help here and there can't hurt
though.

Thanks Rick
I'm looking into a new gps, good to know what capabilities the new
models have.
