This Tanzer model does not do it for me aesthetically but that is neither here nor there. I think Tanzers are well-regarded and the price point leaves some room for fixup. Also, since it is a well-known make it will be a bit easier to resell at some point. None of the issues you mention should be particularly costly to fix other than the sails and you know where you stand with that. You can get some decent used sails pretty cheaply as well. I would consider an offer in your shoes.
Heading back to Lake Ontario for this summer. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.
