Insurance for a wooden boat, new or used can be a problem. Especially given a decades old design...which most likely uses fasteners as opposed to coldmold and epoxy or new construction methods.
In the past things as mundane as fasteners and the process were mandated by insurance companies, even going so far as to have a surveyor assess every one as we re-fastened. The monel ones required had to come out of the box new, and if bent, dropped or damaged in any way, was tossed - could not be used.
Most yards have no way (railway) of moving or launching a wooden boat of this size. You may try Tiffany's yachts of Wicomico Church, VA. There work is impeccable. And they are a pleasure to work with.
Getting a yard to sign up for this scrutiny and the many thousand's of hours may be problematic, unless they know your situation personally. Many have been left hanging on very expensive, resourcematerial hogging unfinished boats, with no means of getting rid of them.
