There's nothing I really disagree with in what you say, I always seem to learn something I didn't know about all this newfangled stuff, and it still boggles the mind the number of 'missed opportunities' to avoid this incidend, given the extent of the tools they had at their disposal...

Having said that, however, for an old dog like me, having both a paper chart of the Indian Ocean at my disposal, and a computer loaded with the requisite charts, the quickest and most foolproof method of discerning the existence of the Cargados Carajos Shoals is gonna be a quick glance at the chart... But again, perhaps that's just me...

My argument has always been, that this would have been the big advantage of paper in this particular incident, in both the planning stages of the passage, and the onboard navigation. Namely, that no matter what scale of the chart being used - or the 'level of zoom, in other words - the landforms and lighthouses on those islands would NEVER have 'disappeared':

According to the report:

"The paper charts would not have to be used for plotting and laying out tracks in order to have helped the crew avoid the grounding. They would simply need to have been viewed to identify dangers in the vicinity of prospective tracks. On paper charts of every scale that cover the area the hazard was clear ."

On the other hand, this is one of the 2 contributing factors of the cause of the grounding, per the report:

"Deficient cartography in presenting the navigational dangers on small and medium scale (or zoomed out) views on the electronic chart system in use. '

The photo below represents the sort of anomaly that I've often run across when using vector charts... At first glance, it would appear that the Nazareth Bank might constitute a greater hazard to a navigator, with it's indication of a number of underwater "Obstructions" and more detailed soundings... And yet, to the south there is no indication whatsoever of the islands, reefs, and lighthouses that exist there - which would seem to me to be of a bit greater import than the submerged obstructions on the Nazareth Bank... (grin)

I can't recall ever seeing anything like this on a paper chart, this sort of 'stitching' of hydrography from different scales, adjacent to one another on the same chart, which might lead to the mistaken assumption at first glance that the Nazareth Bank might actually the area of greater concern to a navigator...
