Re: Sleeping underway risk
If I laid in my rack worrying about hitting a container I'd not be sleeping anyway.
In the Navy you put you head where the light was in the coffin rack - didn't matter which way it was facing. We had belt straps to hold us in on submarines and the smaller ships.
I've only owned 4 boats - all of them had berths that were designed to be feet to bow.
Lessons learned are opportunities earned.
