Jeanneau's from about 82 on have options for aft heads. The smallest that I know of are in the 27-28' deck length range. Arcadia is 28 on deck, hard to find, built from 84-86, sun dream 28 same hull, different deck for a couple of years, then named a sunway 28 for 2-3 yrs. 1000 or so total of these hulls. Size on par with a catalina 28, but 20-30 secs a mile faster, no shower/hot/cold water.
Attalia is 30' LOD, built from 83-88 or so, over 1000 of these built. Fairly common here in the states. again, no amenities as many boats in this range of yrs did and did not have.
If you can go to 36', the sunshine, a Tony Castro design as the Arcadia is, it has 2 and 3 cabin version.
There is another in the 34' range that at this time typing, I am not remembering the name. Of these 4 80's models, the Attalia and Sunshine models are most common.
