Guy, your story makes me want to puke just thinking about it. I have a couple of questions, and you're welcome to blow me off.
What is with the underside of the flybridge? Is the boat supposed to come apart there for wire runs or something, or is this thing really constructed that poorly? Did the engines get flooded, and, if so, were they properly pickled prior to laying up?
And the last and toughest question, why don't you fix her up and keep sailing? You are selling her at a fire sale price, and she is a lot more boat than that. I know that she should have paid for by insurance, but it hasn't worked that way for you. Clean it up, there doesn't appear to be any structural damage, and go on with like and a new insurance company?
Please believe me, I'm not being critical, nor do I know what your skill set is, but I've burnt boats, sunk them, blown up engines, and done lots of bad things to good boats, but I've always re-built them and kept going. The damage to your boat doesn't appear to be that extensive (looking at the pictures).
