I lived on a Cal 25 years back, although narrow the morgan is fine, if you are? I too was single, not much"stuff" and traveled a lot for work. That was in Florida, when I moved to DC, I only lasted until January, before I found a warmer, less hostile situation.
Now I have a Sabre 38, and would not hesitate living aboard at all, year round and still on the bay.
best of luck what ever you decide.
