I have been using them for eight seasons in the Bahamas because my boat came with a Raymarine plotter. I think I began posting
about Navionic's poor Bahamian charts in 2005 or so. Before I posted I corresponded with them and pointed out half a dozen geo-referencing errors. Their only response was that they relied on their own data and would not discuss the specific errors I had brought to their attention. Also they offered me my money
back or a discount on their "new" chip which I ultimately found from other Bahamas cruisers was worse than the "old" chip. Navionics 2004 Bahamas chip is better than later ones when they had to remove data that they had "borrowed".
A few years ago there was a petition going around Bahamas cruisers imploring Raymarine to get off Navionics charts. My reason for stating the facts about Navionics Bahamas charts is to give those that do not yet have a chartplotter
a choice; buy one with good charts or get one whose charts are unreliable. Unfortunately with electronic chart you cannot ascertain their accuracy except in situ. Playing with it at a WM store will tell you nothing about the accuracy of the chart.
As for my posting
being "harsh" I cannot see how highlighting poor charts can be termed harsh. Especially when some of the errors are known to the chart maker and they take no steps to correct it. As for your statement " There are lots of people cruising the Bahamas with Navionics charts and most of them are not running aground and dying" I hope it doesn't have to come to this before we can warn others that charts cannot be relied upon and have the warning termed "harsh".
