How the heck did they attach the bulb keel to the hull ?? Might have been dodgy far Eastern keel flange bolts, or even Monday morning layup blues causing serious delamination around the keel to hull joint or even metal fatigue of the hinge. All new boats should have a good ultra sound survery of the hull and rudder. Not a cheap job in surveyor fee terms.
I hope the boat is still under warranty, as it looks like a constructive total loss.

A bit like a dump truck might be more reliable than a F1 car round Monaco race circuit. But it wouldn’t win many prizes.
Race boat design, scan things and safety margins are very different, for specific reasons.

Actually, I think there is growing evidence that a long keel may contribute to capsizing boats in extreme conditions, where a narrow keel allows a boat to slip sideways and may be less prone to capsize (but clearly more prone to keel breakage).
Certainly there seems to be evidence that cats with daggerboards down trip more than ones without, but there are so many other correlated design factors that probably not able to prove anything yet.

Indeed, but no doubt there were others that did not - but we don't hear about them. Today we hear almost instantly about happenings the other side of the world and the focus is on that and not the thousands of boats sailing offshore that do not encounter any problems if this nature.

It was a "cassette" design with a section of the keel going up into a socket on the hull, then attaching at the top of the socket.
If you look at the photos, I'm pretty sure that the 2 holes on the aft end of the longitunal beam are the keel bolt holes. The fact that there are no bolts there, and no obvious signs of damage could mean that they fell out.. It could also mean that they were removed during salvage in order that they could retrieve what was left of the keel for analysis. Presumably we will find out in good time.
You can see them in happier times in this photo.

IF the two bolts shown in flaming’s photo #69 are the keel bolts supporting 895kg of ballast and subject to some pretty hefty latitudinal stresses then I for one wouldn’t even think about sail an X2 in anything other than a mill pond.
But there again I’m an old fogey still has a respect for traditional long keelers, even though I now sail a bilge keeler.

They wouldn't take the latitudinal stresses. The top of the keel is in the socket, which would take the lateral forces, or at least the majority of them... See picture, the top part goes up into the hull.
Note that the metal keel fin is the same size as the head, the rest is a fairing around it for better hydrodynamics.

I can see how the stresses would not be directly upon the bolts, but the whole arrangement seems to me to be what my engineering pals would describe as ‘insanitary’, but I am only expressing an opinion, it will be interesting to see what comes out of the enquiry.

Whatever else might go wrong with my old boat, I'm pretty sure her keel ain't going to drop off.

Just as well for the peace of mind of other skippers!

Could the keel be welded? Didn't something similar happen to Drum?
That wasn't down to Chinese manufacturing either.
Also, 2m is surely "moderate" swell. Not "extreme" nor even rough.

2m is simply normal, what you get with a F4 with any fetch.
My boat too isn't likely to lose a keel, as she was born without one.
