Don't rely on the gps for altitude. I recall sailing down the ICW
last summer and observing the gps telling me I was converted from a
sub (-40 feet) to a plane (+50 feet) within a few miles. I was seldom
at sea level.

My GPS has a 2D & 3D mode... it is suposed to be more accurate if you put
it in 2D mode telling it that your elevation is constant.
