Thanks for the updated information. I had wondered what time of "day" the accident happened. Right after field day, that figures. Sometimes on my boats we had GMT at the start of the watch after a morning field day so at least 2 watch sections would have been up.
I wonder how many people sustained neck injuries from being thrown forward (or out of) in their bunk.
That's why I personally always slept with my feet towards the bow, if possible. I figured lots of things could bring us to a relatively rapid stop (never dreamed of anything like this, needless to say) - but the chance of getting flung aft by quick acceleration just wasn't gonna happen in a 5,000 or 10,000 ton displacement vessel!
