A friend had a Defiance lose the rig just recently. The damage looked superficial (apart from a missing rig) , but was structural around the chainplates and deck fittings. I never saw it up close, but the boat looks 99% fine from the outside. It was assessed, and the repair quote was about the same as the insured value. The insurance company offered a payout, which the owners took and sadly walked away from the boat. The boat is still on a mooring and will probably go to an insurer's auction shortly. This was a boat in otherwise good condition, and it just looks like it has no rig.
I'm not sure Aus if I'd ever think the boat was the same again, even if they did a good repair, it looks pretty extensive to my untrained eye.
It's probably not what you want to hear, but I think if I was in your unenviable position, I would probably take the insurance payout and move on.
I hope there's a bright side, and in 6 months you have found an even better boat, if that's what you choose to do.
