Basically, it looks like the dust storm has caused an enormous sand bar. The Evergreen is a flat bottomed ship. It is literally sitting on land with some water around it.
The sand has to be dredged, but, actually the entire canal needs to be dredged because the wind is filling it with sand. The canal needs to be made deep again.
No one in Egypt will like this, but, the Suez Canal has been neglected. The region has been so unstable in conflict after conflict that the basic MAINTENANCE was neglected. The Evergreen is not in any significantly deep water. This event, in my opinion is not the captain’s fault.
Where is Israel in all this? They have the engineers to leverage an opinion and perhaps come up with some plans to return function to the canal. Unless, of course, they would rather the canal fill in to create a land bridge.
