an attempt to develop a tacking analyzing system
 
I know I can do better to windward.
I'm hoping to develop a means of analyzing my boat's performance. The chart
was made using my Garmin tracks, AutoCAD 2000, and some notes taking during
the sail.

A J33? (or am I reading that wrong?) Why are you doing so much better
on Port tack than Starboard??? (or am I reading that wrong too?)
Rick ----just curious

Thanks Rick
Seaward 26RK.
Difference if probably due to inexperience and me paying more
attention to speed than direction (was hitting 5 knots with wind on
stb side as opposed to 3 knots on port - although I suppose I had
better VMG at 3 knots). It's part of the learning curve for me to look
at my track and see what tendencies I have that I didn't consider
while doing the actual sail. Plus, it let's me feel like I'm still
sailing even though I'm at work :)
When I get back out there, I'll be more diligent about pointing,
paying attention and trimming the sails.

Good lord Scout...IMO yer ****ing up trying to figure out your boats
preformance on autocad. What's this world coming to?

Proper salt spray in your face as waves impact the bow perfectly,
shape of your sails, and the feel of your helm, and the deck below
your feet is what you need more of.

Tweaking and shaking down on a computor...gawd I'm going vomit.

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.

Joe,
First thing - I'm 100 miles from my boat and need something sailing
related to do! (besides posting here).
Secondly, Since the angles of my tacks are gps accurate and since I
have AutoCAD, and since I recorded the direction of the wind, why not
use all that info to improve my understanding of sailing? I've spent
hundreds on navigation equipment where others spend thousands - why
not make the best use of what I have at my finger tips? Even without
any input from the group, I can see where I was f-ing up. If I did use
just the wind in my face approach, I haven't gotten any better because
the most exciting sailing was when I was going furthest off course!
So, puke if you must, but hang on and I'll check the AutoCAD drawing
to make sure it doesn't blow back on you! :)

I'm just messing with you Scout.
And if you are not going anywhere just sailing around I can relate to
the having fun parts and running on a broad reach no matter the course
made good. Now if you were going somewhere up wind, your charted, or
plotted, or computed , or was it designed course was awlful bad.

100 miles inland...that's as bad a commute as Rob has to his boat.

it much.

wow, your tacks sure make nice sharp angles!

Without the relative speeds at the various angles, looking at the
pointing angle alone will not provide any useful insight. I'm sure the
boat can point higher.

What you need is a polar diagram
http://www.newavesys.com/sailprod.htm
I bet Nick Hake has them for your boat.

Then comes the fun of learning to sail the boat to it's predicted or
potential velocity at the given angle.

Yeah, like a badly misadjusted rig or a keel that's been bolted on
slightly sideways.

Yep, pretty much any GPS should be able to do this. Might have to do
some hunting thru the menus.

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.


Just about any instrument package can spit outthat data too. You just
need a a wind speed & angle input.

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.


The best way is to sail with a good racing skipper... or sail
alongside one in the same class of boat....

IMHO until you've learned to sail the boat well, technology is only a
distraction. Speed is not a number, just like the angle of the boat's
course to the wind is useless info without further info on the boat
speed & the conditions (for example, a pointing angle that is really
good in light air and/or chop is a very poor pointing angle in flat
water & good steady wind).
