Plotter Tide / Current data incorrect

[phantomracer]

Never noticed it til this weekend, the data on the Tide an Current on the plotter (B&G Vulcan 5 with a Cmap chip) is off about 45 mintues to an hour.

yes, the date is correct on the plotter

We were going through the Cape Cod canal, and thought we were late for the favorable current as the data on the plotter was ahead about 45 minutes. Thank goodness the NOAA, etc data was correct

The pic is of a tide station, with different times and tide heights as well.

Is there a setting that isnt set right, or is this an issue with the plotter or the chip?

Hi, same problem with mine: Vulcan7FS and C-Map area Europe West Coast. Tides and Current about one hour off. Also the plotter crashes after several hours if use and than asking for tide or current.
The chart is dangerously incorrect. Missing buoys, harbors and depth.
