I always advocate CBI ("community boating, inc") for meeting people, which is a non-profit sailing organization - they have volunteer opportunities, but I know no details: [http://www.community-boating.org/get-involved/volunteer/](http://www.community-boating.org/get-involved/volunteer/)

(especially if you already know how to sail, you might be able to get an instructor role)
