That looks like an epic fail. Hope the remaining crew are found safe. 20 of 24 already rescued. 4,200 vehicles on board.
Apparently 4200 vehicles on-board https://www.gpbnews.org/post/cargo-ship-overturns-coast-saint-simons-island
Elsewhere it's reported that the ship is owned by Hyundai Glovis, which carries cars for automakers Hyundai and Kia as well as others.
Perhaps for parts but I suspect these were not EVs ... 'cash for clunkers' comes to mind. Speculation on my part but I'm wondering if the recent hurricane might have changed the channel and the harbor 'pilot' didn't pick it up. Poor loading may have also contributed to the problem. If they'd off loaded lower decks and the upper decks were full ... well that would also explain why it rolled. Regardless, that wreck is NOT in deep water. Bob Wilson
A similar event happened in 2006. 4700 Mazdas on board. Cause was a failure of water pumps in the bilge tanks. Exit pump worked, entry pump did not. Without sufficient water in the tanks, it floated unevenly the listed to the side. Then passed the point of no return.
