I did not dispute that, just your point #1.

"1. Any raster electronic chart is identical to a paper chart. The paper/electronic argument doesn't exist with raster charts...."

It very well could be that the islands in the Vestas wreck show up on a Game Boy. But generally, the display of a raster chart on a computer screen vs. offset lithography is not equivalent for me or by any objective measure. I am typing this on one of the highest resolution (the highest?) laptops on the planet. A 30" wide printed chart displays something like 3 times as many pixels. Maybe 12 times as many as the average laptop, and 16 times as many as a largish chartplotter. You can't throw out that much information (95%?) without losing something. Yes I can zoom in and see all of it - little at a time. Not the same. You put blinders on a horse not so they can see more, but so they see less.

I will say once again that I am not anti-electronic charts, I have more electronic chart plotting on my boat than almost anyone here (and apparently more than Vestas). I don't look at paper charts frequently but I typically do have them for the area I travel. And I do look at them for various reasons at various times. Because they tell me something more, or more quickly, than the computer display.
