I think that you will find that there are plenty of caveats about the use of the data on charts and as far as I remember, this applies to the US Chart data as well as UKHO.I wonder how true that may be with the litigious society that is the usa
If the charts were that bad then there would be hundreds of lawsuits
You certainly can't sue the UKHO for duff data, as all they have to show is due diligence. In other words that they have done their best, and the data is the best that there is etc. UKHO even tell you when and by what method the data was collected so that you can make a seamanlike decision about how to treat the charted data for a particular area.
How the data is collected by US authorities is another matter!
