Is the keel fully supported? You should be able to spot deformation by sighting down the hull over the cradle supports. If it was a good cradle to begin with you may be OK. Is the deck/hull joint straight? Or hogged or sway-backed?
Is it a factory lay-up staged boat? As long as the keel is well supported and there is no rig it may be fine. The deck should have protected the bulkheads of the openings were sealed.
Get it surveyed. A bare hull should be at a discounted rate.
