What do you mean by "badly delaminated" ? Where? How big?
Review the injection methods for repairing "soft-spots", as your hull could be repairable. Both this site and the Hobie Forums have detailed descriptions of repairing delaminations.
Though we have good and reputable dealers that frequent this site, I would not take the word of any run-of-the-mill dealer saying YOUR hull is complete toast.-They want to sell you a NEW boat or one of their consignment boats. Ask an experienced sailor to look at your hull.
