I second NightWing's suggestion. Fays Boatyard (
www.faysboatyard.com) is, I believe, the only marina on the lake specializing in sailboats. They will have the know how and the equipment. Moving a 23 ft sailboat off jack stands is not something you should do without safety precautions in place. Also, a trailer designed for a motor boat might not be sufficient, first for the keel design and second for the weight.
Good luck and have fun working on your boat!
