I have to work and have a 15 year old son, so that's not an option for the next few years! I met someone once that lived on his friend's boat for a while- paid rent just like an apartment. I'm sure it's not common, but maybe there is someone out there!
Aloha and welcome aboard!
I hope you can find someone that needs a boat sitter. Try marina bulletin boards and crew lists at marinas. A lot of sailing clubs post ads and I suppose craigslist does too but I'm not certain about that.
