I've been looking at the pictures and I see a few problems.
Even at $18,000 I'm not sure the rotted core replacement and fiberglass work would be worth it.
waterlogged rotting decks (flybridge, and other?)
marine head gone, some type of "composting" head instead
no bow thruster
no windlass, cheap anchor
swim platform crushed in the middle (backed hard into a dock piling?)
What other problems do you old salts see?
