The hull structue was inadequate to resist the bending moments imposed by the great swells. She literally broke in two
Interesting picture! Is that based on sonar images of the bottom of Lake Superior or just some artist’s imagining?
The only problem with the ‘broke in two’ theory is that the entire middle of the ship was ground to powder/vaporized. This would only have happened if the bow struck the lake floor with tremendous force [which it would have done, if the bow had gone under & the screw drove her down] such that the weight/momentum of the stern, driven down by the sudden impact of the bow, destroyed the mid-ship.
