Hey guys, thanks for all the helpful suggestions. I did call Jamie at the Yacht Shop in Halifax that Fitjaraid mentioned, and he was very helpful and even dug up the quote for the mast that they built in 2005, which I forwarded to the surveyor. It's like they say, Canadians are just the nicest people!
I got word today that the replacement value estimate will well exceed the insured value of $20K, so it looks like they'll total my boat and take possession of it soon. We're taking it on one last weekend for the cross-Long Island Sound race, where we'll be race committee (obviously, since we can't compete!) It will be bittersweet to give up Full Tilt after 20 awesome years with her.
The good news is there are some turn-key boats in our price range available right in my home port, so with a little luck, we'll have a boat soon and we'll be back racing in the Thursday around-the-buoys races! Possibly in a J30!
Thanks all! I'll update when we get our next boat.
