Another way to start is to
get out on the water with someone who sails. Try going down to a marina and looking for someone who is working on his or her own boat and talk (don't stop them from working) to that person. Explain your interest and offer to help them with their maintenance if you are handy at all or can at least take direction. I'm not sure about the seasons in LA if at all but most marinas in the Northeast are filled with people working from April till June.You'll learn alot right there and probably get an offer to crew. There is no substitute for actually getting out on the water and sailing with someone who knows what they are doing. You can learn more about what you need to know to get out on the water and sail in one afternoon than you can imagine. For example - apparent wind is an important concept but it makes alot more sense on a boat than in a book. Maybe it's me, I am a visual, sensory learner and doing works best.I strongly advise that you take a safety course from the Coast Guard or Power Squadron before heading out on your own.As far as costs go (based upon a 25' sailboat), other than the purchase price of the boat, you probably have winter hauling and storage - $400 - $1500, summer dockage - $1500 - $4500 or mooring $500 - $1500, paint and routine upkeep $500, engine winterization/spring tuning - $200 - $500, replace an outboard - $3000, replace an inboard $8000, new sails (main and jib - $2200 - infinity...), insurance - $50 - $300, forgetting about work and everything else for a day - priceless. It was running me about $5000 a year not including beer and ice...
