I was going to ask how it was that you had a boat, and had never sailed it, but I'm starting to get the picture
. Hate to break it to you, but it's a terrible time to sell a boat (or almost anything for that matter) Good season, bad economy. If you have to sell it in the near future, I would think now is the time to do it (though I don't know the Florida market). Maybe you could consider taking on a partner with the boat (maybe they'd even know how to sail!
), via, Craig's List "Boats" or your local sailing publications (using all the precautions of course).
I'll be surprised if there isn't a crew list in your area. In fact, here is one (I found in a quick search) in Biscayne. Crew Lists
When I mentioned the crew list idea, I didn't realize you were the OP (Original Poster) who had the boat. You could reverse engineer the process. List yourself as a Skipper (in this case, boat owner), who needs crew who know how to sail. This is what I did when I got my first boat. I had extensive Windsurfing experience, and some experience crewing (through Crew List), but needed someone who was confident with a larger boat. Worked really well, in fact, I've had several people crew who teach at local sailing schools! All the respondents had a fair amount of experience or had owned boats of their own. If your boat has an Owners Association (check the Web) it might be very helpful as well.
All the best!
