As long as you're not going long distance, this really isn't a big deal.
If you do stray off course, the little arrow will always point towards
your target. I use one all the time, and find that once I reach a
destination, my "bread crumb" trail will be a bit curved from point A to
B.


Which I assume is fine, unless that curved course is too big. In which
case
you are traveling a longer distance than you need to or, much worse,
getting
into an area of the water that you don't want to be in (say shallow or
such).
Yes?


Yea, I don't usually use the GPS in shallow areas, I've been though
them enough that I just use landmarks (because Im usually close
to land). I only use it once I get out into the open ocean to find
fishing reefs. Also, I notice that sometimes the bouy is not
exactly where my GPS waypoint is, but that is of no consequence
because you can usually see the bouy once you get within a
mile or two. I don't know that I would want to use the GPS
to nav through shallow areas because the thing (at least mine)
just isn't *that* accurate. Mine doesn't have WAAS. Its a few
years old.

I have the Garmin e-map. I think we paid about $150.00 a few years
back. Nothing to write home about but it gets the job done.
Its fun to take up in the plane on business travel too. It gives
you altitude and such. A couple years ago I was flying back
from Dallas to NC on an older 757 and noticed we had
passed 700mph. I thought it was way off but just
then, the captain came on the intercom and announced
our speed as 700mph+. We must have had a helluva
tail wind that night.

But generally we'll just be going short distances so you're right,
it probably isn't a big deal. Just like to think it all through anyway.

Have fun.
