I have a Norman 23. On mine, the dinette has been removed and replaced with a single bench seat, so my boat sleeps three. When made up for three to sleep, there isn't much room left for all their things! (Where the dinette is still in place, the resulting double bed is narrow for adults, but it would be OK for 2 children, I think.) As built, the N23 had quite a roomy cockpit, as Chevron says, and many of them have been converted to give comfy outdoor seating which, depending on how it was done, could be used as sleeping space for smaller people. They are good, strong boats.
