The Sabre was the first model to get the all fiberglass stringers, transom and floor. You can look in the back and see if the sides of the foam boxes are slick gel coat and finished. If so, then this is probably an all fiberglass model. Though some all glass models had a urethane composite 36 pound glass loaded transom. We chose to not og that way, and finished our all glass vacuum transoms by mid 1999. There is no way to know if it is an all glass model. Though if it is a rounded style boat without a fin, it has glass stringers and flooring.The Warranty technically dies on Lifetime Warranty if the second owner chooses not to Transfer it. The parties that be in the company will have to evaluate your rig and the history of that rig to reactivate that warranty if it was not registered.The Registration is intended to remain active to keep the boats under the policy. A 1999 Sabre has no warranty remaining, though may be built the same as those which have one. The Quest Membership will apply to all modelsBCB
