SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

But either way, it's either taking on water or it's poised to take on some more water.

And so being lower into the water, it's getting hit by these giant waves that we know are happening.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

And so it's hitting the back, which pushes the front down and that causes water to kind of cascade into the deck.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

But all this hemming and hawing, the jostling of the ship can cause what's known as hogging and sagging into an extreme case.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

These kind of things can crack a hull.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

So hogging, yeah, yeah, yeah.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

And obviously we know the ship is in half at the bottom of the lake.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

And so this theory does have an interesting point here.

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

So hogging, I believe, is where, you know, the crest of the wave is happening under the middle of the ship.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

This isn't to say that the ship is out of water or anything, but that the front and the back are less held by the water, which would mean that the middle would bow upwards, right?

SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

sagging is kind of the opposite.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

When the wave is first hitting the back, and maybe another wave is leaving off the front, the front and the back are being lifted up by the wave, but there might be a trough from the wave in the middle, which means that the middle of the ship would sag.

So to your very vivid picture, it's like if the waves are coming at a certain cadence, you almost hit, you almost, you know, this is definitely the wrong mechanism here, but you almost hit a resonant frequency where...

The middle of the ship is bending up and bending down and bending up and bending down just enough to create fatigue, right?

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

If you look at something like a paperclip and you bend it, okay, it bent.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

That's structural failure through fatigue.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

It's one of the first things you learn in structural engineering.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

And most of that has left my mind.

Red Web
SS Edmund Fitzgerald | What Caused This Tragic Sinking in the Great Lakes?

So don't quiz me.

But that's essentially what this theory is saying.
