A cross track error of 1 mile can lead to unexpected rocks -unless you
know from the chart all; is well. Of course you are also sailing further...

So I take it that you only used the GPS on occasion to verify your chart
plot and rightly considered a cross track [drift] error of one mile in 20 as
not worth concern as long as you knew where you would be on arrival to
corrected waypoint?

Excellent Bob... this is what I was hoping to gently persuade you to discuss
in the first place.

I often find myself too lazy to tweak and set trim to compensate for this as
well... especially when I have dinner in the oven and the heel is perfect
for cooking while underway. Good Show!

NOT where we were sailing with miles of good water on either side of us. The
deviation did not go unoticed, nor did it effect our TOA.
