Fully extended berth showing head-first sleeping arrangement. Shown are two, queen size pillows. We bought two flannel sleeping bags, good to 40 degrees, for $136 at LL Bean. We unzipped them, using one for the bottom, which sat on top of our fiberbed topper, and the other was used as a comforter. Overall, this sleep space is roughly 6 feet long by 5 feet wide, with a slight decrease to 4.5 feet at the bulkhead. We slept better is this berth then we did at home. 9/26/12 comment. This berth is a lot larger than one would think. I can sleep across the bunker once past the bulkhead. The only issue with sleeping toward the bow is the deck is close to one's head, but that's OK after awhile, since you have a cavernous view of the cabin from that perspective as well as having the hatch overhead. Another thing that should be considered is that if any of you suffer from heartburn like I do, you know that it is infinitely preferable for your head to be higher then your feet. Sleeping with your head toward the bow achieves this.
