I'd just like to say I've just last year gone through a similar problem.
I had a 460 with ingress in the balsa core in most of below the waterline hull. - a little in the sides of the hull as well. The finding of such an extensive problem with delaminating was sickening. Mine was a demo boat 2000 model but delivered to me 03. After a few heated conversations and me airing my frustration Searay really came to the party. They sent people all the way out to Fremantle in Australia at their cost to inspect the problem. They then spent the next 3 months putting a whole new bottom on the boat and reglassed the sides. It looked brand new when completed and I could not fault any of the work that was carried out locally and inspected by Searay. During this process I decided that I didn't want a boat that had such extensive repairs and they traded it back at fair market value and I purchased a 48 Sundancer at a price that was too good to refuse - there happened to be a demo 48 in town- they really looked after me on the price. I can have nothing but praise for Searay and the local dealer as well. Neither walked away from the problem and they still have one very happy customer - me. This is my 5th Searay.
Good luck - I hope it turns out as good as mine did.
