'87 here (#80). I suppose one could live aboard indefinately; with water stops as mentioned above. Two with a mild climate (no heavy clothes and lots of time in the cockpit). I've known bachelors who live year-round aboard smaller vessels - but you'd have to keep pretty spartan tastes and few hobbies.
We use ours as a lake daysailor and it excels at that. I wouldn't hesitate to take her coastal provided the rig is well inspected. Getting on 21 years for any remaining original equipment.
On the whole she's rugged, somewhat tender but has a good motion (she does not bob, slap or root like many "European" recent 30 to 36 foot designs) and is very well laid-out for livability. Very wide side-decks reduce the cabin volume but sure make sailing and fishing at anchor a better experience. Seems to have very good ventillation and is relatively light and cheery inside. Loading her up for a live-aboard would probably make a big difference in the tenderness as she'd be squatted on her lines.
