In a box or in a boat?!?!

So Lance, my friend that bagged me to move down here (Vero Beach) decided to bolt on me. He is no longer here living with me. Having this come up, leaves me without a "roommate". I do not really want to have a random roomie again, I've already done that....twice...and both times were a flop! Therefore, I am looking for a place of my own. (Should be a mini-adventure within the big adventure) But I am looking for different places and I have decided on one thing. If you think back to some typical movies you watch, you will be able to recall in some, a guy just climbing out of an old crusty wooden boat that he lives in. He has a little bunk/bed kinda thing, a little shower, mini kitchen and a "bathroom area" and thats about it. So remembering that....please close your eyes and think of me in that!!! Ok, so thats where I wanna live. I think "what an adventure that would be" Something totally different and fun! Something I can tell my kids years down the road, I was the fun kid who lived in a boat, and it was a blast! But those are just some thoughts. My only problem is that I do not know where or how to get "involved" with something like that. I mean, seriously, you cant just call up people selling boats and say, "Hi, Im now to town and I was interested in buying your boat, but I was wondering...could you live in it?!" I mean come on now...Let get real! So my question is...What do I need to do, who do I need to talk to in order to live in a boat? Thats what I wanna do!!!! Any suggestions?
