horrible that this would have happened, but I guess with all this new stuff (technologies, materials, design) a catastrophic breakdown was bound to happen at some point.
Heck, even a "regular" capsize would put one hull almost 4 stories in the air. A fall from that (even on water) would likely cause serious injury.
Let's add about 40 knots of boatspeed to that equation and I shudder to think what "could" happen.
I recall something about "Drum of England" having a keel fall off and causing some injuries, and I'm sure I could bring up all kinds of fatalities due to boat breakdowns (mono and multi) if I searched, but it's still sad to read of tragedies like this..
What would really add insult to injury is if no recommendations are made to improve safety based on their investigation
