-- Some states have free or inexpensive boating safety classes
-- Libraries will have books
, maybe also sailing/boating videos.
-- Some yacht and sailing clubs have weekly / monthly/ annual open houses; occasionally they might even put boats in the water
for people to ride
-- Clubs might be a good place to ask "Are there any owners who'd sail more if they had crew?"
-- Volunteering to help the race
committee is another way to meet people and see sailing up close, and maybe get some good commentary
-- Community sailing programs and some clubs may offer relatively low-cost sailing time
-- Hanging around boat ramps and hoists, as well as walking docks where accessible, could be productive.
-- Of course you will sign up for yacht/sailing club crew lists (mostly on each club's web site) and be honest about your experience and stress your dependability and punctuality plus ability to listen and learn.
-- Perhaps a charity that takes kids
or special needs people sailing, or a community sailing program, could use volunteers.
