Re: How to sleep
I sailed back from Bermuda on a Beneteau with a big queen bed aft. Only the aft side of the bed was against the hull, so there was walking space along the other three sides. After a midnight to 3:00 am watch at the tail end of tropical storm Curtis, with the boat tossing and heeling horrendously I found it almost impossible to sleep on the bed without sliding or rolling off. Finally I hung my arms, head and upper torso over the side, positioned like I was about to pull myself over a wall, and managed to sleep some, due to sheer exhaustion. They clearly weren't thinking of big seas when they designed this boat.
The skipper said he didn't want us sleeping on the settees in the saloon, because his wife didn't want sweat stains on them or something like that. After 24 hours I rebelled and jammed myself between some gear on a settee and slept like a baby.
