If you are an “experienced” cruiser (aka old person) you probably remember the days of Selective Availability (SA) and intentionally reduced GPS accuracy. The military only let us know our location within 100 meters. This continued for years, despite ongoing pleas from the FAA and USCG to provide everyone with the accuracy available from the GPS satellite system.
It took a jetliner being shot down to turn off this reduced-accuracy SA.
Today we could not live without accurate GPS information. At home, on the road, and on the water.
It’s been a long time coming but we now see tangible progress emerging to reduce our dependence on fossil fuel. If the U.S. Navy can prove that it works, isn’t it about time the concept of the modern cruising boat includes hybrid forms of propulsion?
