A little paint and polish and that will be good to go......
Seriously, many have seen real wood restoration projects..... sometimes all that's left after demo is the keel, all or part of stem and stern, some or most of the ribs, rarely any of the planks and hopefully most of the deck frame and the frame of the superstructure and the interior, and that's on a boat that didn't spend too much time under water.
There's tens of thousands of hours and hundreds of thousands of dollars of work there, IF there is enough sound wood to work with.
Of course all of the systems, and much if not most of the hardware need replacing.
Edit: This boat has quite the history, but it appears we're dealing with John Steinbeck here and not Hemingway...
