Shriff,
Nothing whatsoever is wrong with your idea or desire to live a-board a boat. (I have been living on mine full-time since 1993.) Furthermore, I have always been a lover of big (live a-board size) boats, boating and the sea... Thus my life has revolved around it. I have for over 40 years, had one or more such boats.
Tip #1 Live a-boards are an odd lot. We come from all backgrounds, and incomes. In my marina right now, there are doctors, lawyers, teachers, airline pilots, one preacher, one college student, several retired couples and singles, two families with small kids, and two (very popular I might mention) marine engine mechanics. From there, we also have a range of live a-boards including a couple of retired older then salt boat bums. While our incomes vary dramatically, the one thing we all have in common is a love of the water, and respect for mother nature and each other.
We have all seen many - many "live a-board wannabes" come and go. Most arrive thinking it is:
1. a "cheap" lifestyle or 2. a party lifestyle - both of these are very far from the truth.
Live a-board marinas are very much like middle to upper class suburban neighborhoods. People go to work every morning, and return in the evening to a quite, peaceful life on the water. While our friends on land have yards to mow, we have woodwork to finish, brass to polish, engines to tune...
So... my first tip is that if you think it is a "cheap" way to live - it is not. People that move on to their boats thinking they will improve their financial conditions - are the one's that hate living on their boat the most, and move out ASAP.
After that... Those that think living a-board full-time is the same kind of "party life" that the see on those weekends at the lake that God made for boaters... they are the first to go.
TIp #2. Finance - What makes "living a-board" so financially appealling to so many of us, is the fact that we have "paid for" vessels. It is then, (and only then, in my opinion) that living on your boat makes any sense at all financially.
Most Marinas will charge you a minimum of $10 per foot (boat length)... Therefore, if you have a 30' vessel, you are out $300 a month in slip rental... You also have utility hook-ups (water, electric, cable, etc. and in some cases sewer or pump-out). That will quickly add up to another $200.
Now that's not bad at all... until you add boat payments, boat insurance, and boat maintenance.
Regardless of what anyone says, if you seek a live a-board size and seaworthy vessel in good enough shape to sail and live a-board the day you buy it... you can expect to pay at least $20,000.
If you find anything cheaper (in California) in a live a-board size vessel that is ready to live on, I would be shocked and amazed - if indeed - it is also seaworthy.
The Marina will want 2 months deposit (mine now, requires 3), plus you will have all your utility deposits... as most boat slips are now individually metered. Cabin heat will not be near the problem or expense as air conditioning for your boat... and I promise you this... Nothing on earth gets hotter inside then a small sailboat's interior cabin space. You will not be able to sleep, or anything else inside during the long Los Angeles summers. Your air conditioning will cost you upwards of $300 a month just to stay comfortable at night.
Now... there you have it. I would give this same advice to my son, except he is now 42 years old and living on his boat and spends most of his time in the Caribbean.
So what I am saying is that it is a wonderful dream - if that is what you really want. It is a great lifestyle - if that is what you really want... And, I certainly encourage you... But to be "successful at it, you have to go into it with your eyes wide open, and for all the right reasons.
Good luck,
John
