Hi, a little help please... and just to let you know of something potentially dangerous if navigating in limited visibility by electronic chart alone.

Here's a screen shot of my chart software when zoomed to 0.2m viewing a region around the SW of the river Dart (note the pink highlighted zone):



Here's a zoomed in view of what's in the pink highlighted bit from the above image:



Anyone tell me why there's the error where the chart boundary is? It's suggesting to me that one side of the boundary is shifted and hence not accurate... got to be at least an error in one or other of nearly 100m!!

Location is: N50 19.487 W3 35.222

Is this normal?

PS. This is from Garmin Mapsource running the latest (9.5) BlueChart software for the channel.

Update. I called Garmin tech support and got through to the marine charts section. The guy at the end of the phone admitted to me that this is definitely not meant to be like this, and that it's definitely a mistake in the charts. He said they'd call me back, but that was over a week ago now, so I guess they're not going to

The fact that the error is there in the first place doesn't bode well for the chances of them ever getting back to you. Thankfully I don't think I'll be sailing that area, bit far for me
