A customer of mine has a Dell laptop running the latest Coastal Explorer. The boat icon on the laptop is off by about 50 feet, compared to the Garmin plotter where the GPS data is coming from, and also just by looking out the window.
The lat/lon numbers match EXCTLY between the Garmin and the laptop. Yet, the boat icon on C.E. is about 50’ to the east, compared to the Garmin, and the view out the pilothouse window. Also, other boats on AIS are showing on land, when they are actually in the water in the first slip in the marina. Raster and Vector charts both have this issue. It is like the chart is shifted about 50’ to the west. Any suggestions?
This happens with both a Keyspan serial to USB converter, and an Actisense NGT1 N2K to USB converter.
I have only observed this while the boat is stationary in it’s slip. I have not been out on the boat while underway to see if this error goes away when the boat is moving.
I have pictures but cannot see how to attach them.
