In later models, the rear berth runs across the boat from port to starboard. I intentionally chose the older 88 model 37 Legend BECAUSE the bed runs fore to aft because I knew I would frequently sleep while underway sailing. When taking a trip with mixed crew I have them stow their baggage along sides of bed making a dam to keep from rolling out and I made a simple net that stretches tightly down the centerline of the bed to semi-separate it into 2 berths. No matter which way the boat heels one person rolls downhill to the baggage dam on their side while other person rolls downhill to the net divider. All folks who are able to sleep well on a boat can then sleep through rough sailing, storms, etc. w/o rolling on the floor and nobody has all the blood draining into their head. BUT< if my main sleeping time was at a dock, I might prefer the side to side arrangement. So, how do you intend to use your boat? Take your pick.
