I have not lived on board. However, I have spent a lot of time on the water and in a few different marinas. I was going to mention that it is always safer on the boat when you are not solo. If you have a mate life is a lot easier (as long as you get along). The other thing I'd mention is there are marina communities where if you rent a hook you get access to the amenities, like bathrooms, showers, laundry, repair services, etc. I am not sure how mobile your life is but this is worth looking into. I hope you fall in love with the sea.
