IMHO a 40 foot boat is the minimum for
living aboard. That is, if you want a fairlynormal life. You will want a kitchen (galley) that has something like the minimal appliance at a normal working height. You will want a dining table and standing
head room. You will want stowage space for your
winter cloths in the summer and viceversa. You will want a
head with a
shower and sink. As for the small floor space, I have found that the limited boat
interior is compensated for by the unlimited exterior. And finally, the everyday expenses are quite managable even in a marina. I have lived on my
Columbia 41 for five years and really could not live ashore again.
