I keep reading about GPS for boats and how innacurate it can be.
Why is the same not innacurate in cars?
My car GPS is so accurate it tells me I am on the white line at a
traffic signal stop light or in my driveway.
Why not the same for boats?
There are two parameters here - the accuracy of the GPS and the
accuracy of the chart or map that it is being tracked on.
When I have the tracking on the car GPS it sometimes has me parallel
to the road but off it by a considerable amount. Most of the time the
tracking on the boat is very good. If there is a discrepancy it is
often because the chart or map is off.
