I find Garmin Bluecharts basemap off about 50% of the time. Not far most of the time but up to 200 ft occasionally. In the Okeechobee Waterway my boat is shown driving over land almost the whole length. The ICW, about 50-100 ft off in SWFL. Now items placed on the charts like daymarks and buoys are usually right on.
