Welcome Kim. Post here in the crew section for sailing opportunities in PR
. Also check out the World Cruiser's Forum on Yahoo, and CruisingNet. Many yacht clubs require membership to go in, or that you be an escorted guest. So try to make contacts first. Walk the docks at marinas and talk to sailors. Do be careful about crewing, a small boat on a journey with odd people can be very stressful (I know). Good luck in your adventures.
