Largo delight,
Tartan 37 (It can sleep one couple and a single),
Morgan 34 (very spacious for its size), If you are considering cats a
Gemini 30-33 (?), I stayed on one but don't remember the exact length. The
Gemini had three separate staterooms and sailed pretty good. There are a lot of boats that fit your criteria, good luck!
