Good thread BR. Always a bit of thought goes into your threads. It is appreciated.
It does strike me that as boats get bigger and having all the comforts of home becomes more important that many of the issues raised get shifted sideways or ignored altogether.
If you'll pardon a bit of old fartiness I'd suggest that some of you have a look at the interior of the older crusing boats such as the Hiscocks Wanderer III. While by today's standards she is small, cramped and lacking in many of the bare necessities of life (Good Lord the thing doesn't have air conditioning or a TV, let alone hot showers, positively barbaric conditions
) she does have as central to the accomodation two decent sea berths and plenty of handholds.
I was once sailed across the top of Australia in a 26'er that in almost every respect I found unbearably cramped but she had port and starboard quarter berths, fit for a single body only, that enabled me to sleep like a cat all the way across with nary a bruise or a bump.
Then again, as someone mentioned, most people never spend more than the very occasional night at sea so all that se berth, small cockpit, gumph matters nowt to them.
