Ok, I just read more about the ongoing investigation.
Apparently, there may have been a series of failures (human and technical) that allowed the yacht to take on water and sink so fast.
It's all in an Italian news article that isn't worth linking as it's mostly behind a paywall. However, the main points are:
1) A bridge hatch that was left open;
2) the boat's swing keel left up, basically a mobile keel that can be raised and lowered. The boat was anchored, so the keel should have been down; with it raised the vessel was less stable and more susceptible to yawing and rolling;
3) the yacht's positioning. No details on this aspect, but I imagine that it should have been pointing in the general direction of the wind;
4) a delay in the ship's automatic lock-down (seal-all-the-hatches sort of thing) in cases of emergency.
I'm sure more information will come out in good time.
