Firstly, ask yourself these questions.
Why do I want a boat to live on?
Why do I want a sailboat to live on?
Why do I think a 20 foot saiboat might be a good liveaboard choice?
Who are you living with? Do you have a partner and one or more dogs?
How much stuff do you need to live?
I suggest that if you want a boat simply to live on because you like living on the water then get a barge on some nice waterway. You can watch the ducks all day in comfort from a large deck, then retire below to a spacious lounge, kitchen and bathroom.
I suggest that if you want a boat to live on and go sailing you think very carefully about how much sailing you intend to do. I have seen many a sailboat that clearly hasn't been to sea in years, festooned with bycycles, plants, swinging chairs etc and I always wonder to myself; "doesn't that mast and rigging really get in the way!"
If you only sail once in a while then any old boat will do to live on. You can go sailing on other peoples boats and not have to spend three hours stowing clutter before you finally cast off.
I have personally lived on my Flicka for 2 years and enjoyed it very much. However, I was single and didn't have too much gear and I still found it a struggle at times.
In my opion one person can live in reasonable comfort on a Flicka as long as there are showers at hand or the weather is warm enough to shower on deck. It is also possible for a couple to cruise in comfort and harmony for months at a time on a Flicka.
What really helps is having a garage or lock-up nearby where you can store all the stuff you don't need while you're living aboard: cleaning materials, tools, books, spare sails and cloth, anchors, dinghies etc. This can really make living on a Flicka so much easier.
As a long term live aboard option for a couple I would find it very difficult on a Flicka and in that case would look at larger options such as the Dana 24, Orion 27 and Crealock 31.
