You could probably sell it for the price of the motor. The boat has negative monetary value as a sailboat. Replacing the spars and rig is going to be expensive. If you can find the rig off of a similar boat for cheap or free, that is your best bet at getting some benefit from the possession of the boat.
Negative value depending on the area. They sell between 8 and 11K here. I bought one a few years ago for $5500 that was quite dirty. I cleaned her up and did some varnishing and sold her 2 years later for $10500.00 They are great boats. Good luck selling, but don't give it away.
