Re: GPS Accuracy - how much is actually needed

Back in the summer of 2001 I was sailing solo up the east coast of the US, somewhere around NJ the fog set in as I was heading for a small inlet to pick up a mooring for the night. There was a marker at the mouth of the inlet with a bell on it that I could hear but could not see in the fog. Because of the fog, I could not determine what direction the sound of the bell was coming from. The night before, as was my custom, I put all the way-points for the next days sail in my handheld GPS. So I turned the GPS on and followed it directly toward the buoy. The buoy broke out of the fog at 12:30 off the bow at about 50 yards away. With map in hand I safely navigated past the rocky shoreline into the inlet where I was met by the harbor master's assistant who escorted me to my mooring for the night. Without GPS I would have turned seaward and spent another night on the open sea - something I really would not want to do in the fog. That little GPS was the best $150 I ever spent.
