The Luder's 16
has a cuddy cabin big enough to sleep a couple adults overnight:
"The L16 is sloop-rigged sailboat. The "L" is for the designer, A. E. (Bill) Luders, and the sixteen represents the waterline length of the boat. L16s are twenty-six feet long overall and have a working sail area of 207 square feet. The boats have a small cuddy cabin with sitting headroom and, optionally, two berths for spartan overnight accommodations."
