We've had some mention of sleeping on board the DSII, but not too many specifics. On the spur of the moment, I spent last night on the lake, and therefore am now an expert:
1. Space per se is not a problem. There's as much room as in a backpacking tent.
2. One person is not a problem: You move all the junk in the cabin to the other side of the mast. Two people would mean you have to put everything in the cockpit.
3. The cabin slopes aft. That's a good thing. It means it can drain. But it means that sleeping in it is like camping in a backpacking tent set up the wrong way on a slope. (You do NOT want your head in the forepeak, unless you wear a hard had to bed). Next time: Extra foam pad for the aft part of the cabin.
4. Mosquitos can be a problem (this has been mentioned on the forum), so I dropped anchor at the edge of the channel, where a 5 knt breeze cleared the bugs and rocked me to, um.... see the next bullet point.
5. Your ear is REALLY close to the water. Waves from 5 knt breeze ring like the gong of bell inside the cuddy. Next time: Earplugs.
6. There is nothing half so much worth doing as swinging at anchor late a night, sitting in the cockpit strumming a mandolin, hearing the breeze ruffle the rushes, and watching the moon rise. So what if you get back to the dock at dawn and drain the office coffee pot in an effort to not fall asleep at your desk?
