Garmin Anomaly

[GordyP]

Probably won't affect many folk. There is an anomaly on Garmin plotters when going through the Cuan Sound between Seil Island and Luing, just at the point where you have to keep well off the Seil shore (to avoid the rocks)and stay in fairly close to the wee island with the marker on it - the plotter shows the boats position to be to far to the SE. If you take the correct line the plotter shows you sailing over the island, i would therefore imagine that if you followed the plotter it would in fact take you over or very close to the submerged rocks. Maybe not to much of an issue in a shallow draft rib but i wouldn't want to test it out.

Anyhoo, if you are passing through and have a Garmin plotter bear this in mind, I have to also say that this is the only place that i have found it to be off.

The GPS we have on the Atlantic is spot on just about everywhere apart from the harbour we use!
You could enter Whitby and go alongside just using the GPS. Going in and out of Staithes it shows you running through the pier!

I had something very similar a few years back and notified Garmin about it. They confirmed my observations and said that the chart had been embedded slightly out of sync when originally scanned by the Chart supplier

Gordy is that just as you are going round the dog leg thru the channel when you swing to the north?

Yes exactly that, just conveniently where the rocks are to avoided on the Seil shore.
