The report stated that they were using only the base world map of their CMap charts, and did not even load the actual charts into their computers
. They had those detailed charts, they just didn't load/unlock them. The picture shown is from the base world chart (basically, a plotting sheet).
They also deliberately turned off all the textual and visual warnings and safety
systems on their charting program that would have alerted them to the fact that land existed in that area, and that there was a more detailed chart available.
In addition to their 2 computers
(which they did not load detailed charts onto), they had 2 B&G chartplotters on board. The base world map on these chartplotters showed land existing on those shoals on all zoom levels. They were using one of the chartplotters to control their lights, and did not look at the other chartplotter
until they were on the bricks.
The CMap charts of that area are not the best, but they do contain information on that shoal sufficient to keep even an amateur, half-asleep, navigator from bricking on it.
As you show, Navionics
are even better, as are the official HO ENC
vector charts - which show that land at all zoom levels.
So to sum up, they were not even using their electronic charts - instead relying simply on a world base map plotting sheet. They had deliberately turned off all warning and safety-checking systems in their navigational software
. They had FOUR chart plotters on board, two of which clearly and unambiguously showed the dangers. They chose only to use/look at one of them (and picked the wrong one). They did not choose to use official HO ENC
charts on their software, which show these dangers at all levels, although it seems in hindsight that they wouldn't have been anymore successful if they did.
So, while I expect that most here will see in this report a damning of electronic charts, I see absolute navigational idiocy - lower than amateurish. If I were the navigator of this boat, I would be deeply ashamed and embarrassed by the findings. I certainly would not continue to hang on the "electronic charts were the problem" excuse.
Let me state this again: two of the four chart plotters on board clearly showed the land and shoals at all levels (on only their world base map, no less!), while they failed to even load the electronic charts they did have into the other two computers being used as their "main" chart plotters. Failed to load the charts!
One has to work very hard in contortions to blame this on electronic charts.
