I feel for you. That has got to suck. Nice boat, good money and it breaks all by itself. You did what most people do.You enjoyed your boat and put it way for the winter and it broke all by itself. Sure there are things you could of done that "maybe" could of delayed it, like move south, but there's no guarantee.There's nothing you could of done to prevent it, that's the part that sucks. Hunter should own up to their product and stand behind it 100%. I do hope you are keeping a log with names, dates with discussions and their outcomes and are considering a consult with an attorney. Good luck and don't back down. I'd post the pictures on every sailing site available and mention that this could happen to your Hunter too. Good luck and keep us updated. Some out here want to know Hunter did the right thing by it's customers.
Keep it up,
