I have been lightly following this thread and agree that the enhanced accuracy of DGPS is not needed in off-road or recreational boating. The high accuracy has been developed for use in surveying and vessels that rely on GPS for dynamic positioning. I'm sure the military has a stake in it too.

GPS is fun and easy, but try not to rely too heavy on it. I have been aboard vessels on more than one occasion where the old LORAN or GPS signals we received were inaccurate, mostly because of equipment failure on the vessel. All GPS systems warn you at start up not to rely solely on their device.
