eBay is a good option if you simply want to be rid of it once and for all. Yes you can set a reserve and make sure it is realistically low or you might not get a bid over it. I feel it is good to get a bid or two early on. It increases interest. You need to get serious buyers to come see the boat.
Be sure to clearly state as is, where is. Look at other sailboat auctions for examples of what works and what doesn't. The only problem I see is your location. You are presenting to a limited market. If it were on the coast so the new owner could sail it home it would be worth more because there would be more interest.
Is it in the water
or on the hard
If the engine was already removed and in New Orleans
I could go $2000 for it and the prop. So it should be worth that to a local. But once again you are playing to a limited market.
