Yeah, I mean, the funny thing is that m- this is racing.

The truth is these are very technical boats.

So that was a, what's called a, um, um, a fabricated keel.

It was a steel keel, so we'd gone away from the carbon.

We'd gone a steel fabricated keel, supposedly a very safe and light solution.

Um, and what had happened is some point in the Southern Ocean or at Cape Horn, it had developed a crack filled with water, and then there'd been a thing called, uh, some special fast corrosion, because it's very aerated, the top of the keel.

Mm.How do you know where that is?
