Do people in
NYC sail in January? I don't think so!
Do what Boatie suggested. Triage the garbage into known junk, may be junk, known valuable. Latter two to garage, store room or whatever. Clean thoroughly. Then you can start fresh when and as ready.
But Don's right, you know, sail her the very first opportunity you can make. That's how you find out how to prioritize the jobs. All boats have jobs they want you to do. It's life.
