If there is the slightest wind at anchor, the cabin is cool all night. (At the
dock we
sometimes rigged a windscoop if we weren't facing forward, but hardly ever need
at
anchor.)

We slept aboard many times this summer. We never had a problem sleeping and it
was often cold at night when anchored. A 12 volt fan was used maybe twice.
We always use the main cabin's double.
The "cave" of the 34xl will have to be addressed with some alterations, but
it's better than a bunk that's too small!
