Re: spent my life savings on a boat, looking for work.
I think good for you. Your priorities are in order. Sail first look for work second. Walk around the boatyards and ask the people bottom painting and doing maintenance if they need help. Or you could buy wax and polished and stuff and offer to clean people's boats.
Get either a scuba tank or an air compressor and walk the docks telling people you will clean their bottom for 20% less than they normally pay.
Find a tourist sailboat that takes people on sunset sails and ask the captain if he needs a deckhand willing to work.
Find a charter tourist fishing boat and learn to be a deckhand.
These are all things I have done and started with no experience. You've got to walk the docks and yards. It's actually not that hard. Put an ad on the for sale sailboats of craigslist offering your services. Be positive all the time even when you don't feel like its so they want you to come back and like having you around. Good luck you'll be fine.
