We have a Legend 37 with the centerline/pedestal bed in the rear cabin. I loved the idea when we purchased the boat, and I don't dislike it, but probably don't like it as strongly as I thought I would.
On the hook or at dock, no complaints. But under sail, particularly going to weather, I could see the athwartship would be a better solution, especially if trying to sleep two people.
Our solution is to keep some packed spinnakers (dry of course) down the middle of the bed, to act like a lee cloth. Otherwise the 2 people end-up on the low-side... the high-side person pressing the low-side person into the cabinets and/or off the bed. Not so bad if you're married... but the wife and I don't sleep while sailing to weather... so that scenario is during racing... I like my crew, but not looking to be that close while off-shift. Stacked sails work really well to divide the bed!
Anyway, just my 2-cents... YMMV
