Firstly, most modern ships (especially ones that large carrying millions of dollars of goods) have automated systems to assess damage to the important parts and alerts engineers.

Speaking of Engineers, theres at least a few on a private YACHT, this is a huge commercial carrier which means most likely the majority of the crew are engineers, and they definitely have diving/SCUBA equipment on board to assess damage. What if something happened in the middle of the ocean? You wouldnt sit around twiddling thumbs hoping for a country to send a team out "next week."

Currently the ship is approx 2Nmiles away from the nearest part of the coast and if it managed to make it through the main canal and most of the lake then the likely call would have been for it to continue up the next (much shorter) branch canal so it could reach the Ismailia port for repairs.

Also on the location of the ship, if they were worried about the hull why would they not anchor up once they were immediately in the Great Bitter Lake (theres even a little gulf they could have gone in) and out of the way of traffic? Why continue almost to the other end of the lake before stopping?

Nothing this ship has done, or continues to do backs up your claim about potential hull damage. If it was severe enough to stop them moving they wouldnt just be sitting ducks in the middle of the lake, they would have been towed to the port, or at worst to the coast so the cargo and people could be salvaged. It's an intentional stop, nothing to do with damage to the hull.
