I thought we were in SA forum here, and not in a court. I expressed my "theory" here, which is nothing else than my guess.

It looks like the sail drive - not the keel stub

Possibly.
Another guess is : the tiny wedge snapped off (if it's made out of cast iron, it's not so ductile as forged steel to just bend without breaking), then bolts came off from the turtled hull...nothing to keep them in place without the wedged-in keel...unless some piece remained attached to the bolt threads.

Interior photo when boot in good condition shows a round plate with goop and two bolts (but even could be nuts).
Wreckage photo, it looks like no plate. But need a more close up photo to really make a conclusion.

It looks like the keel may be similar to the Farr 280 keel as far as how it is attached. Found this manual showing how it is attached:

I'm pointing to the little grey bumps forward of the sail drive.

Glad I have horizontal bolts across the keel head.

Indeed, you wrote your 'Guess' before stating we should not speculate.

Interesting there is 6 mm gap between keel and hull. Not a little play for the keel to wobble (possibly around +/-1°). This means significant bending for the bolts if not properly torqued (guide says 99 Nm)...loose bolts might be a possibility as Zonker saidIt looks like the keel may be similar to the Farr 280 keel as far as how it is attached.

Yeah but I meant "not torqued enough" in that sense. Or just loosened due to vibrations/impacts (hitting lots of waves). Interesting topic - transverse vibrations in a bolted joint (like a keel fin bouncing sideways) are MUCH worse than axial vibrations. Loc-tite or safety wire or cotter pin your mission critical bolts/nuts. Airplane and race car people learned this a long time ago. Marine people not so much.
You wouldn't want much of a gap between keel head and keel socket. Doesn't transfer the load very well.

Yeah, looks like 2 12mm SS bolts. that's about 16 ton capacity for a 900kg keel, should be sufficient.

Glad the crew are recovered. Job Well Done to the crew of HMAS Brisbane for the rescue.
Farr X2 Australia said "The boat was sailing into a building breeze and significant seaway when the keel attachment failed resulting in a capsize". (https://www.yachtingworld.com/news/...ed-hull-of-new-farr-x2-after-keel-loss-139333).
Interesting to note that Hull #2 which was slated to race in the Pac Cup withdrew, prior to the loss of Hull #1. Have to think they would have had to withdraw after this incident.
Finally, I note that the shitter is still intact in the boat. Which has to lead to the obvious conclusion that if the keel had been installed as well as the shitter was, this thread would not exist. (jkg).

Interesting that the quote above in that article seems to be the complete opposite regarding conditions to what the statement from Nexba earlier in the article says.

Presumably this, you silly bunt. “Around 1am on Saturday morning as the team made their way home to Sydney in light to moderate breeze and 1-2m seas, the boat capsized.

If you owned #2 or had one on order, you'd have to be very worried.

The bolts are possibly somewhere on sharkey beach . Possibly remained in the cabin until it got smashed

They would’ve known if the keel bolts were coming loose in a 1-2M swell . I’ve had two boats with lift keels and if the keel wasn’t bolted down snuggly even the smallest movement of the keel in a seaway is very noticeably transmitted through the hull . I reckon they pulled out of whatever they were tapped into or rather the keel did
